Question

Draw a well labelled diagram of animal cell and mention one function of the main cell organelles.

Answer 1

Following are the main cell organelles:
(i) Nucleus: It controls all the metabolic activities of a cell and regulates the cell cycle.
(ii) Endoplasmic reticulum: They provide skeletal framework to the cell and are concerned with the production of lipids and proteins.
(iii) Ribosomes: They play an important role in protein synthesis.
(iv) Mitochondria: They are the powerhouse of the cell as they provide energy to the cell by performing cellular respiration.
(v) Golgi apparatus: It is involved in the synthesis of cell wall, plasma membrane, and lysosomes.
(vi) Lysosomes: They are the cellular housekeepers and form a kind of garbage disposal system of the cell by removing worn out or damaged cellular organelles.
(vii) Vacuoles: They help in maintaining the osmotic pressure in the cell. and also in storing excess nutrients and molecules.
(viii) Peroxisomes: They carry out certain oxidative reactions (detoxification) and remove the toxic substances from the cell.
(ix) Centrosome: It helps in cell division in animal cell.
