Write a short note on:
1. Mitochondria
2. Golgi apparatus [5 MARKS]
Each point: 2.5 Mark
1. Mitochondria: There are double membrane structures present in both plant and animal cell. Outer membrane is smooth and inner membrane is folded to form finger like projections called cristae. It is the site of cellular respiration. ATP is formed inside the cell. ATP is the energy currency of cell thus its called power house of the cell.
2. Golgi apparatus: It is formed of several flattened vesicles stacked one above the other. Synthesis and secretion of enzymes and hormones takes place here. They are called the post box of the cell.
