(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.
