What is Mitosis and Where does it Occur?

Mitosis is a kind of somatic cell division in which the mother nucleus (n or 2n) divides into two daughter nuclei passing through a series......

Define Amitosis with the Mechanism Process with Diagrams

Amitosis:  The process, by which a cell divides directly producing two daughter cells without following any intermediate stages like mitosis or meiosis, is called amitosis.......

Describe Chromosome with Kinetochore

Every chromosome essentially has a primary constriction or the centromere on the sides of which disc shaped structures called kinetochores are present (Figure). Based on......

Describe on Nucleus

Nucleus as a cell organelle was first described by Robert Brown as early as 1831. Later the material of the nucleus stained by the basic......

Describe on Centrosome

Centrosome is an organelle usually containing two cylindrical structures called centrioles. They are surrounded by amorphous pericentriolar materials. Both the centrioles in a centrosome lie......

Functions of Lipid

Explain on Different Types of Lipid

Here explain some common types of Lipid: Tri-glyceride (Fats & Oils): Tri- glyceride is a lipid, composed of fatty acid and glycerol. Triglyceride is formed......

Define and Describe on Cilia and Flagella

Cilia (sing.: cilium) and flagella (sing.: flagellum) are hair-like outgrowths of the cell membrane. Cilia are small structures which work like oars, causing the movement......

What is Cytoskeleton?

An elaborate network of filamentous proteinaceous structures present in the cytoplasm is collectively referred to as the cytoskeleton. The cytoskeleton is a composition that helps cells......

What are Ribosomes?

Ribosomes are the granular structures first observed under the electron microscope as dense particles by George Palade (1953). They are composed of ribonucleic add (RNA)......

Explain on Mitochondria

Mitochondria (sing.: mitochondrion), unless specifically stained, are not easily visible under the microscope. The number of mitochondria per cell is variable depending on the physiological......

Describe on Chloroplast

The chloroplast contains chlorophyll and carotenoid pigments which are responsible for trapping light energy essential for photosynthesis. In the chromoplasts fat soluble carotenoid pigments like......
