Metaphase – Definition, Stages, Applications
Metaphase is a stage of the cell cycle that occurs in both mitosis and meiosis cell division. During this stage, individual chromosomes cannot be observed in the cell nucleus.

Cytoplasm – Functions, Structure, Definition, and Diagram
The cytoplasm, a highly viscous substance (gel-like) that is enclosed within the cell membrane. It is composed of water (about 85%), proteins (10-15%), lipids (2-4%) and nucleic acids, inorganic salts, and polysaccharides in smaller amounts. Depending on the cell’s configuration, cytoplasm might also contain occasional inclusions (e.g. stored nutrients and pigments).
Plant cell – Structure, Definition, Diagram, Organelles
Animals, fungi and protists are composed of at least one eukaryotic cell. However archaea and bacteria are composed of only one prokaryotic cell. Plant cells differ from cells belonging to other organisms due to their cell walls, chloroplasts and the central vacuole.
Stroma in chloroplast and Stroma in Animal Tissue
Stroma, as a term in botany, refers to the transparent fluid that surrounds the grana inside the chloroplast. In the stroma, there are the grana (stacks of the thylakoid) and sub-organelles, or daughter cells in which photosynthesis begins prior to the chemical reactions being completed within the stroma.
Membrane Carbohydrate – Types, Structure, and Function
Membranes are made up composed of proteins, carbohydrates, and lipids that are held together with the help of binding forces.
Prokaryotic Cell and Eukaryotic Cell
In the previous article we learned about cell structure and functions. Now in this article we will learn about Prokaryotic and eukaryotic cells. Introduction Hey, if I told you, that you are surrounded by 100 trillion bacterial cells, would you believe? Yes, If you look closer than you will find trillions of bacterial cells on … Read more
Cell Structure and Functions – Cell Organelles
A cell is like the tiny building block that makes up all living things, from plants and animals to bacteria. Imagine it as a microscopic bag filled with stuff that keeps life going. Every cell has a thin outer layer called a membrane, which holds everything inside and controls what goes in or out. Inside, … Read more
Bacterial Transformation Protocol
Bacterial transformation is a process wherein bacteria naturally modify their genetic makeup by incorporating foreign genetic material into their own genome. This phenomena has significant ramifications for health care, agriculture, and environmental science and has evolved into a fundamental genetic engineering tool. Scientists can create life-saving medications, alter crops for improved features, and speed up … Read more
Archaebacteria – Definition, Types, Characteristics, Structure, Examples
What is Archaebacteria? Definition of Archaebacteria Archaebacteria, also known as Archaea, are a group of single-celled microorganisms that belong to one of the three domains of life. They are distinct from bacteria and eukaryotes in terms of their genetic, biochemical, and physiological characteristics. Archaebacteria are known for thriving in extreme environments such as hot springs, … Read more
Eubacteria – Definition, Structure, Characterisitcs, Types, Examples
What is Eubacteria? Definition of Eubacteria Eubacteria, also known as true bacteria, are prokaryotic microorganisms that belong to the domain Bacteria. They are single-celled organisms lacking a nucleus, with DNA organized in a single circular chromosome. Eubacteria can be gram-negative or gram-positive and have economic, agricultural, and medical significance. Examples include E. coli, Lactobacilli, and … Read more
