To function properly, cells must be kept turgid. To function properly, a well-watered plant will grow and produce fruits and flowers. A plant that is not watered for several days will wilt and eventually die. This happens because water leaves the cell and causes the cell to lose its turgidity. Based on the concentration of … Read more

What is An Autotroph? Definition of Autotroph An autotroph is an organism that can produce its own complex organic compounds (like carbohydrates) using simple substances such as carbon dioxide, typically through processes like photosynthesis or chemosynthesis, without relying on external sources for carbon or energy. Types of Autotrophs Autotrophs, which are organisms that make their … Read more

What is Heterotroph? Definition of Heterotrophs Heterotrophs are organisms that rely on eating other living things for their nutrition and energy, as they cannot produce their own food. Types of Heterotrophic Nutrition In the natural world, living things use different ways to get their food when they can’t make it themselves. These are the main … Read more

They are distinct from flatworms and higher segmented anelids. Characteristics of Phylum Nematoda  Classification of Phylum Nematoda  Nematoda is one of the most diverse phyla. At present, there are approximately 15,000 species. … Read more

Definition of binary fission (What is binary fission?) Binary fission can be described as a kind of sexual reproduction in which one living cell, or organelle expands twice its size, and then splits into two identical cells, which means that each of the daughter cells can be expected to grow to what size as the … Read more

What is Monera? Definition of Monera Monera is a historical biological kingdom encompassing prokaryotes, which are unicellular organisms lacking a distinct nucleus. This kingdom primarily included bacteria and archaea, and its members are characterized by the absence of membrane-bound organelles. Over time, taxonomic classifications have evolved, and the term “Monera” is less commonly used today. … Read more

The study of embryology, also known as embryos, is a key element of evolution in biology and can identify the commonalities and differences between different species. The embryo of an organism refers to the fertilized egg that it progresses through the stages of development, which are unique to the particular species. In examining how the … Read more

What is Facilitated Diffusion? Facilitated diffusion Definition Facilitated diffusion is a passive transport process in which specific molecules move across a biological membrane with the aid of specialized transmembrane proteins, following their concentration gradient without the direct use of energy. Principle of Facilitated diffusion – How does facilitated diffusion work? The principle of facilitated diffusion … Read more

Definition of Simple diffusion  Simple diffusion is one of the types of passive transport that is, as the name implies is the simple movement of solute that happens when the electrochemical potentials of one side of the permeable barrier differ. Principle of Simple diffusion/How does simple diffusion work? In free diffusion across a membrane, solute … Read more
