What is Ecological Succession? Ecological Succession Definition Ecological succession is the systematic and predictable process by which species composition in an ecosystem changes over time, progressing from initial colonization to a mature and stable community. Characteristics of Ecological Succession Ecological succession is a fundamental concept in the realm of ecology, delineating the sequential transformation of … Read more
What is Pyramid of Number? The Pyramid of Numbers is a graphical representation used in ecology to illustrate the distribution of various species in different trophic levels of a food chain. This pyramid provides a quantitative analysis, showing the number of individual organisms present at each trophic level. Unlike other ecological pyramids which might consider … Read more
What is Prokaryotic Cell? What is Eukaryotic Cell? Difference Between Prokaryotic and Eukaryotic Cells Feature Prokaryotic Eukaryotic Nucleus Absent; genetic material located in a nucleoid region. Present; genetic material enclosed within a nuclear envelope. Membrane-bound organelles Generally absent (e.g., mitochondria, chloroplasts, endoplasmic reticulum, Golgi apparatus). Present (e.g., mitochondria, chloroplasts in photosynthetic cells, endoplasmic reticulum, Golgi … Read more
What is Bacteria? Bacteria represent a category of microscopic, unicellular organisms that are classified as prokaryotes, characterised by the absence of a membrane-bound nucleus and organelles. These organisms are found in a wide range of habitats across the planet, including extreme environments such as deep-sea vents and arctic ice, as well as more common settings … Read more
What is Bright Field Microscope? What is Dark Field Microscope? Difference Between Bright Field Microscope and Dark Field Microscope Feature Bright‑Field Microscope Dark‑Field Microscope Image Background Bright Dark Specimen Appearance Dark/stained specimens appear visible Unstained specimens appear bright against dark Illumination Transmitted white light through specimen Oblique/scattered light; direct light blocked Contrast Mechanism Light absorption … Read more
What is Holobasidium? What is Basidium? What is Phragmobasidium? Difference Between Holobasidium and Phragmobasidium Holobasidium and Phragmobasidium are two distinct types of basidia, which are reproductive structures found in fungi belonging to the division Basidiomycota. These structures play a crucial role in the life cycle of these fungi, particularly in spore production and dispersal. Understanding … Read more
Difference Between Virus and Viroids In this article we will discuss about Differences Between Viroids and Prions. Virus Viroid Difference Between Virus and Viroids – Virus Vs. Viroids Feature Virus Viroid Genetic Material DNA or RNA, single- or double-stranded, linear or segmented Small circular single-stranded RNA molecule Capsid/Coat Protein coat (capsid); some have additional lipid … Read more
In some places, phycology is also called algology. It is the study of algae, which are part of the plant kingdom.
Biosafety refers to the practices and precautions taken to prevent harmful biological agents—like viruses, bacteria, or toxins—from accidentally harming people, animals, or the environment. Think of it as a set of rules and tools scientists use to stay safe while working with dangerous germs. To organize these safety measures, experts created biosafety levels (BSL), which range … Read more
What is Southern Blot? What is Western Blot? Southern Blot vs Western Blot Here is a detailed comparison between Southern blotting and Western blotting: Feature Southern Blotting Western Blotting Target Molecule DNA Protein Purpose Detection of specific DNA sequences within a complex DNA sample Detection and analysis of specific proteins in a sample Developed By … Read more
What is Northern blotting? Northern blotting is a technique in molecular biology that allows for the detection of specific RNA sequences in a complex mixture, offering valuable insights into gene expression patterns. In 1977, James Alwine, David Kemp, and George Stark at Stanford University introduced a method that was cleverly named “Northern blot,” referencing … Read more
Southern Blotting is a molecular biology technique used for the identification of a specific DNA sequence in a collected DNA sample.
