kingdom Mona was first proposed by Ernst Heckle in 1866 as part of his three
0:05
kingdom classification system initially Heckel considered Mona a subkdom within
0:10
his kingdom protista which included all single-sellled organisms over a century
0:16
later in 1969 RH Whitaker elevated Mona to kingdom status in his five kingdom
0:22
classification system this significant change recognized the fundamental biological differences between
0:28
proaryotes and ukareots proariots which include all monerins lack a true nucleus
0:34
their genetic material floats freely within the cell in contrast ukarotes have their DNA contained within a
0:40
membrane bound nucleus a fundamental structural difference that justified separating these organisms into
0:47
different kingdoms in the 1990s Carl Wos made a
0:52
groundbreaking discovery that transformed our classification of life he analyzed the genetic sequences of
0:58
ribosomal RNA a component found in all living cells w's research challenged the
1:04
traditional five kingdom classification system that had been used for decades
1:09
based on his findings Woose proposed a new three domain system that replaced the traditional five kingdoms under this
1:17
new system kingdom mana was divided into two separate domains bacteria and
1:23
archa this reclassification was based on significant genetic differences between these two groups of
1:30
proarotes bacteria and archa show fundamental differences in their cell membrane composition with archa having
1:37
distinctive ether linked lipids they also differ in their RNA polymerase structure with archa having a more
1:44
complex structure similar to ukariots additionally unique genetic markers
1:49
distinguish archa from bacteria despite their similar cellular structures this reclassification was
1:56
revolutionary because it recognized that despite their structural similarities as proarots bacteria and archa represent
2:04
distinct evolutionary lineages today WOI's three domain system has become the
2:10
standard classification framework in modern biology replacing the traditional five kingdom
2:18
system monanss are proariots which means they have a simple cellular structure
2:23
that differs significantly from ukareotic cells unlike ukarotic cells
2:29
proarots lack a membranebound nucleus instead their DNA floats freely in the cytoplasm in a region called the
2:35
nucleoid proarotic cells don't have membranebound
2:41
organels such as mitochondria or chloroplasts this simple cellular organization was the first to evolve on
2:48
Earth making monines the most ancient form of life appearing approximately 3.5
2:54
billion years ago these simple cells were able to reproduce through binary fision a form of asexual reproduction
3:01
this simple structure allows procarots to be incredibly adaptable and successful thriving in virtually every
3:08
environment on Earth most bacteria in kingdom mona have
3:14
a distinctive cell wall structure the cell wall is a rigid structure surrounding the bacterial cell let's
3:21
examine the composition of this cell wall in more detail the cell wall of most bacteria is composed of
3:27
peptidoglycan a polymer consisting of sugars and amino acids peptidoglycin has
3:32
a net-like structure with sugar chains connected by amino acid bridges this mesh-like structure provides rigidity
3:39
and protection to the bacterial cell while maintaining its shape the cell wall composition is a key
3:46
characteristic used in bacterial identification and classification through techniques like grahamstaining
3:53
the Grahamstain technique differentiates bacteria based on their cell wall properties graham positive bacteria have
4:00
a thick peptidoglycin layer which retains the crystal violet stain appearing purple under the microscope
4:07
gram negative bacteria have a thinner peptidoglycin layer and an additional outer membrane they appear pink under
4:14
the microscope as they don't retain the primary stain the cell wall serves several
4:20
important functions for bacterial cells the rigid peptidoglycin structure provides critical protection and helps
4:27
maintain the cell shape the cell wall provides protection against external pressures and maintains cell shape and
4:34
integrity it prevents the cell from bursting in hypotonic environments and serves as an attachment site for other
4:41
cell components beyond its structural role cell wall composition is crucial for bacterial classification determining
4:48
antibiotic sensitivity and influencing pathogenicity
4:54
ribosomes are essential cellular structures responsible for protein synthesis in all living organisms in
5:00
monorins which are proarotic organisms we find a unique type of ribosome that
5:05
differs from those in ukareotic cells proarotic cells contain 70s ribosomes
5:11
while ukareotic cells contain larger 80s ribosomes this difference in size is a
5:16
key distinguishing feature bacterial 70S ribosomes are composed of
5:22
two subunits a small 30S subunit and a large 50S subunit these subunits come
5:27
together during protein synthesis to form the complete 70S ribosome during protein synthesis the
5:35
ribosome moves along messenger RNA reading the genetic code and assembling a chain of amino acids
5:42
the structural differences between bacterial 70S and human ads ribosomes
5:47
make bacterial ribosomes an excellent target for antibiotics many antibiotics
5:53
specifically bind to the 30S or 50S subunits of bacterial ribosomes
5:58
inhibiting their function without affecting human cells this selective targeting makes the
6:04
bacterial ribosome one of the most important targets for antibiotic development
6:11
the unique structure of bacterial ribosomes continues to be a focus of research for developing new antibiotics
6:18
to combat resistant bacterial strains monerins reproduce primarily through
6:23
asexual methods with binary fish being the most common binary fision is the primary
6:30
method of reproduction in bacteria in binary fishision a single bacterial cell divides into two identical daughter
6:36
cells the binary fision process occurs in three main steps first the bacterial
6:42
DNA replicates creating two identical copies of the genetic material next the
6:47
cell elongates stretching to almost twice its original length finally the cell divides in the middle forming two
6:54
identical daughter cells each with its own copy of DNA some bacteria also reproduce through
7:00
a process called budding in budding a small outgrowth or bud forms on the parent cell the bud grows in size while
7:08
remaining attached to the parent cell dna is transferred to the bud and eventually it develops into a complete
7:14
cell finally the bud detaches from the parent cell becoming a new independent
7:20
cell these simple reproductive methods allow for rapid population growth under
7:25
favorable conditions starting with a single bacterial cell let's observe how
7:31
quickly the population can grow through binary fision after one generation we have two cells after two generations the
7:38
population has grown to four cells by the third generation we have eight cells and by the fourth generation the
7:44
population has expanded to 16 cells all in a short period of time under optimal
7:50
conditions some bacteria can divide every 20 minutes allowing for exponential growth of bacterial
7:57
populations mons exhibit various forms of locomotion using specialized structures
8:04
fleella are whip-like structures that propel bacteria through liquid environments the fleellum rotates like a
8:11
propeller pushing the bacterium forward through its environment some bacteria use peely
8:18
which are hair-like appendages for a type of movement called twitching motility twitching motility occurs when
8:24
bacteria extend pyli attach to a surface and then retract the pyli to pull
8:30
themselves forward other bacteria glide along surfaces without visible
8:40
locomotist surfaces using mechanisms that are still being
8:45
studied bacterial mobility allows for taxis which is directed movement toward
8:50
nutrients or away from harmful substances chemotaxis is the movement of bacteria toward higher concentrations of
8:57
attractants such as food sources as bacteria detect chemical gradients
9:03
they adjust their movement preferentially moving toward beneficial
9:10
substances bacteria exhibit various forms of taxis including chemotaxis in response to chemicals photoaxis in
9:17
response to light and aerotaxis in response to oxygen to summarize bacteria utilize
9:23
diverse locomotion mechanisms including fleella pili gliding motility and directed movement through taxis
9:35
aria now classified under the domain archa are single-sellled organisms that
9:40
can survive in extreme environments where other life forms cannot archibacteria are classified into
9:47
different types of extreophiles based on the extreme environments they inhabit thermophiles thrive in extremely hot
9:54
environments like hydrothermal vents with optimal growth temperatures between 80 and 110° C halifiles live in highly
10:04
saline environments such as salt lakes and salt flats where salt concentrations can be up to 10 times higher than
10:11
seawater acetaphiles survive in extremely acidic conditions with pH levels between 0 and three such as
10:18
acidic hot springs and mine drainage methanogens produce methane as a metabolic byproduct and live in
10:24
oxygen-free environments like deep sea sediments and the digestive tracts of
10:30
animals archibacteria have distinct cell structures that set them apart from
10:35
bacteria archibacteria possess unique cell membrane lipids with ether bonds
10:40
instead of esester bonds found in bacteria they also lack the peptidoglycen cell wall that is
10:46
characteristic of bacteria the environments where ary bacteria thrive today are remarkably similar to
10:53
the conditions on early Earth 4 billion years ago this similarity suggests that
10:59
ary bacteria may resemble some of Earth's earliest life forms providing scientists with insights into how life
11:06
evolved on our planet and potentially how life might exist on other
11:11
worlds archibacteria represent one of the three domains of life separate from both bacteria and ukarotes genetic
11:18
studies show that archibacteria are more closely related to ukarotes than to bacteria their study provides crucial
11:26
insights into the nature of the last universal common ancestor and the early evolution of life on Earth helping
11:33
scientists piece together how all modern life forms came to
11:38
be uacteria or true bacteria are the most common and diverse group of monins
11:45
ubacteria come in various shapes and forms including spherical cockshi rod-shaped basilli and spiral-shaped
11:57
sporilla ubacteria have cell walls made of peptidoglycin a complex structure of
12:02
sugars and amino acids that gives them structural integrity this feature is unique to true bacteria
12:11
uacteria are found in virtually every habitat on Earth they thrive in soil where they contribute to nutrient
12:17
cycling in water bodies as part of aquatic ecosystems and within the human
12:22
body as part of our microbiome uacteria include both
12:28
beneficial species that are essential for ecosystems and human health as well as pathogenic species that cause
12:34
diseases beneficial bacteria assist in digestion nitrogen fixation and food
12:40
production pathogenic bacteria cause illnesses such as strep throat food poisoning and
12:47
tuberculosis ubacteria reproduce through binary fision a simple form of asexual
12:52
reproduction first the DNA replicates then the cell elongates finally the cell
12:58
divides into two identical daughter cells many ubacteria are motile using
13:05
structures like fleella to move through their environment the flegellum rotates like a propeller pushing the bacterium
13:12
forward to summarize ubacteria are the most common and diverse group of procariots their cell walls contain
13:19
peptidoglycin they exist in virtually every habitat on earth include both beneficial and harmful species and
13:26
reproduce through binary fision
13:32
cyanobacteria are a group of photosynthetic procarots formerly classified as blue green algae they have
13:38
a simple cellular structure with characteristic internal philyloid membranes where photosynthesis occurs
13:45
what gives cyanobacteria their distinctive blue green color is their unique combination of pigments
13:51
chlorophyll a for green ficoyanin for blue and ficoythine for red
13:57
cyanobacteria have played a crucial role in Earth's history through their oxygen producing photosynthesis like plants
14:04
cyanobacteria perform photosynthesis converting carbon dioxide and water into sugar and oxygen using sunlight energy
14:12
about 2.4 billion years ago cyanobacteria triggered the great oxygenation event transforming Earth's
14:18
atmosphere from oxygen poor to oxygen rich this fundamental change in atmospheric composition made complex
14:24
aerobic life forms possible paving the way for the evolution of animals plants and eventually
14:34
humans mons remarkable metabolic diversity unmatched by any other group
14:39
of organisms they can be classified into four main metabolic types based on how
14:45
they obtain energy and carbon photoroes like cyanobacteria use sunlight as their
14:50
energy source and carbon dioxide for building their cells chemroes obtain energy by oxidizing inorganic compounds
14:58
such as hydrogen sulfide or ammonia while still using carbon dioxide as their carbon source photoheterotroofs
15:05
use light for energy but unlike photoroofes they require organic carbon compounds finally chemoheterotroofs the
15:12
most common type use organic compounds as both their energy and carbon sources this metabolic versatility allows
15:19
monines to inhabit virtually every ecological niche on Earth from sundrenched ocean surfaces where
15:26
photoroofs thrive to deep sea hydrothermal vents where chea convert
15:31
sulfur compounds to energy from nutrient-rich soils where photootroofs capture both light and organic matter to
15:39
animal intestines where chemoherotroofs break down complex molecules this metabolic diversity is fundamental to
15:45
global ecosystem function monerins drive essential processes like decomposition
15:51
nitrogen fixation and carbon cycling their metabolic capabilities allow them to thrive in environments from deep sea
15:58
trenches to hot springs and even within other organisms monines play a crucial role as primary
16:05
decomposers in ecosystems among these bacteria like basillus and pseudomonus
16:10
are particularly important for decomposition processes the decomposition process
16:16
begins when bacteria secrete enzymes that break down complex organic matter these enzymes digest complex organic
16:23
molecules externally breaking them down into simpler compounds the bacteria then absorb these simpler compounds for their
16:30
own metabolism and growth through decomposition monerins
16:35
recycle nutrients back into the ecosystem these recycled nutrients become available for plants and other
16:41
producers to use when plants and other organisms die they become organic matter
16:47
that decomposers break down completing the nutrient cycle the decomposition activities of mons are
16:54
essential for ecosystem functioning in several ways without bacterial decomposers dead organic matter would
17:01
accumulate and nutrients would remain locked in complex forms unavailable to other
17:09
organisms nitrogen fixation is the process of converting atmospheric nitrogen into biologically available
17:16
forms such as ammonia nitrogen fixation is crucial because
17:22
most organisms cannot use atmospheric nitrogen directly nitrogen is essential for building amino acids and nucleic
17:29
acids making it fundamental for all life forms this process enables biological
17:34
productivity in ecosystems and contributes significantly to soil
17:40
fertility several bacteria in kingdom mana can fix atmospheric nitrogen two
17:45
important examples are riseobium and atobacttor riseobium forms a symbiotic
17:52
relationship with legume plants such as peas beans and clover the bacteria invade the plant roots forming
17:59
specialized structures called root nodules nitrogen fixation has
18:05
significant agricultural benefits it increases soil fertility naturally and
18:10
reduces the need for synthetic nitrogen fertilizers farmers often use crop rotation with
18:16
legumes to enrich soil nitrogen content making it a more sustainable farming
18:23
practice cyanobacteria are remarkable photosynthetic proarots that produce
18:28
significant amounts of oxygen for our planet unlike other bacteria cyanobacteria contain chlorophyll and
18:35
specialized structures called thyloid membranes where photosynthesis occurs
18:40
through photosynthesis they capture sunlight to convert carbon dioxide and water into glucose and
18:48
oxygen historically cyanobacteria played a crucial role in Earth's development
18:53
about 3.5 billion years ago Earth's atmosphere contained almost no oxygen over billions of years cyanobacteria's
19:00
photosynthetic activity gradually oxygenated the atmosphere eventually creating conditions suitable for aerobic
19:07
life forms today marine cyanobacteria continue to be vital oxygen producers
19:14
species like prochloric caucus are among the most abundant photosynthetic organisms on earth these microscopic
19:20
organisms contribute approximately 30% of the ocean's oxygen production prochloricus alone is estimated to
19:28
number around three octillion cells worldwide and can be found at depths of up to 200 meters in clear ocean waters
19:36
these cyanobacteria maintain a continuous oxygen cycle that sustains marine ecosystems and contributes
19:42
significantly to the air we breathe the human digestive system hosts
19:48

20:25
is crucial for blood clotting and bone metabolism and several B vitamins needed for energy production and nerve function
20:34
beneficial gut bacteria form a protective barrier against harmful pathogens they occupy ecological niches
20:41
preventing colonization by disease-causing bacteria they also produce antimicrobial compounds and
20:47
stimulate our immune system to fight infections the gut microbiome is
20:52
increasingly recognized as crucial for overall health about 70% of our immune

chalera caused seven major pandemics from the 19th to early 20th centuries
21:58
tuberculosis was known as the white plague and was a leading cause of death in the industrial
22:05
era bacteria cause disease through several mechanisms some produce toxins
22:10
that damage host cells others directly invade tissues multiplying and spreading
22:16
throughout the body many trigger harmful immune responses that cause inflammation and tissue damage
22:23
understanding these pathogens is crucial for disease prevention and treatment vaccines train the immune system to
22:30

to bacteria archa possess unique genetic and biochemical characteristics that
33:10
place them closer to ukariots in some respects their membrane lipids are ether
33:15
linked rather than est they possess histone proteins similar to ukariots and
33:21
they share more translational and transcriptional machinery with ukariots than with bacteria the unique position
33:27
of archa in the tree of life has profound evolutionary significance they may represent a crucial link between
33:34
bacteria and the more complex ukarotes although kingdom mana is now
33:40
taxonomically outdated it study remains fundamental to various scientific fields
