- The site of aerobic respiration where ATP (cellular energy) is produced.
- They are 0.5-1.5 µm wide and 3-10 µm long.
2) Lysosome:
- Contains digestive enzymes which are kept separate from the cytoplasm by the surrounding membrane, but can be used to digest invading cells or break down worn out components of cell.
- Its size is 0.5-5 µm in diameter.
3) Golgi Apparatus:
- Synthesises and modifies proteins, lipids and carbohydrates. It also makes ‘Lysosomes’.
- Its size is 2.5 µm in length.
4) Ribosomes:
- The site of protein synthesis (or production of protein)
- Its size is 0.025 µm in diameter.
5) Nucleus:
- Contains the cell’s genetic material (DNA) and controls all the cell’s processes.
- Its size is 5-10 µm in
