Cytoplasm:
The cytoplasm is the fluid content inside the plasma membrane with cell organelles embedded into it. The jelly-like fluid between the plasma membrane and nucleus, where many organelles float. It enables cellular chemical reactions and helps move materials around the cell.
- The cytoplasm helps in the exchange of material between cell organelles. It acts as a store of vital chemicals such as glucose, vitamins, etc.
- The part of the cytoplasm without organelles that stores essential substances like amino acids, glucose, and vitamins is known as the cytosol.
- The cytoplasm is all the contents inside the cell membrane, excluding the nucleus. And protoplasm includes the cytoplasm and the nucleus of the cell.
- In animal cells, the cytoplasm is thicker and denser, while in plant cells, it is thinner and pushed to the edges due to the central vacuole.
