(b) Mitochondria: It is the site of cellular respiration or oxidation of food in a cell.

(c) Golgi apparatus: It is involved in the synthesis of cell wall, plasma membrane and lysosomes.

(d) Lysosome: It helps in intracellular digestion.

(e) Ribosome: It helps in protein synthesis inside the cell.
