Question
Write the main functions of atleast ten cell components.

Answer

The ten cell components are:
i. Plasma membrane: It acts as a semipermeable membrane and allows only selective substances to pass through it.
ii. Chromosomes: To carry hereditary characters of an organism from one generation to another.
iii. Lysosomes: Breakdown of unwanted macromolecules is the main function of these organelles.
iv. Ribosomes: These help in protein synthesis.
v. Nucleus: Control centre of the cell. It contains cellular DNA (genetic information) in the form of genes.
vi. Mitochondria: The main function of mitochondria in aerobic cells is the production of energy by the synthesis of ATP.
vii. Nucleolus: Biosynthesis of ribosomal RNA (rRNA) and acts as a platform for protein synthesis.
viii. Cell wall: It provides protection and rigidity to the plant cell.
ix. Chloroplasts: These are the sites of photosynthesis within plant cells.
x. Endoplasmic reticulum: Serves as channels for transport of materials.
