Cell Differentiation: Definition and Importance

Why Cell Differentiation Is So Important

Cell differentiation is the process by which a single cell splits into two different cells. In other words, it’s how we grow from a zygote to a human being. Differentiation is important for all living things because it ensures that each body part has the right number of cells and that no one cell gets … Read more

Epithelium: Definition, Characteristics, Types and Functions

The animal body consists of the some elementary tissues.  The tissue which forms a limiting and lining membrane (epithelial membrane) and covers the free surface of an organ is known as epithelial tissue or epithelium. Characteristics of Epithelium Presence of basement membrane on which the epithelial cells are set; In this case, basement membrane is … Read more

Difference Between Plant Mitosis and Animal Mitosis

The cell division is the process by which organisms generate new cells. By this process, a single parent cell divides and creates identical daughter cells. During cell division, the parent cell duplicates its genetic material (DNA) and transmits to the daughter cells.  There are three types of cell division such as amitosis, mitosis and meiosis. … Read more

Meiosis: Definition, Types, Stages and Significance

Dividing cell is one of the important events in our life which divide each day, each hour, each seconds. In this process, a single cell divides to form two cells and again two cells produce four cells and so on. This process is known as cell division or cell reproduction.   The cells of the … Read more

Mitosis: Definition, Stages of Mitosis and its Significance

The old cells divide to produce new cells. In this case, a single old cell divides into two cells and these two new cells again divide to produce four cells and so on. Generally, this process is known as cell division where a parent cell divides into two or more daughter cells.The capability of cell … Read more

RNA: Definition, Types, Structure and Functions

Johannes Friedrich Miescher (a Swiss physician and biologist) first discovered the Nucleic acids as ‘nuclein’ from the nucleus in 1869. Severo Ochoa de Albornoz (a Spanish-American physician and biochemist) discovered the RNA synthesis mechanism in 1959. He won the Nobel Prize jointly with Arthur Kornberg in Physiology or Medicine for his discoveries. In 1965, Robert … Read more
