- Protoplasm is the living matter that makes up all living organisms. It is composed of a complex mixture of organic and inorganic molecules, water, and various ions.
- Protoplasm is found in all animal cells and is responsible for all of the cell's activities. It contains all of the cell's organelles and structures, including the nucleus, mitochondria, endoplasmic reticulum, and Golgi apparatus.
- Protoplasm is also responsible for the cell's metabolism, the process by which the cell converts nutrients into energy.
- Animal protoplasm is also highly organized, with different regions of the cell performing specific functions. For example, the nucleus contains the cell's DNA, while the mitochondria produce energy.
