Animal cells are also known as eukaryotes. Some of the key eukaryotic organelles and their functions are:
- Nucleus: contains and protects the genetic material in a cell. The genetic information is needed to carry out all the activities of the cell. One can think of genetic material as set of instructions or rules that must be followed for all the functions of the cell.
- Mitochondria: also known as the powerhouse of cell. Mitochondria is responsible for production of energy in the form of adenosine triphosphate (or ATP) molecules. This is possible through the process of aerobic respiration which takes place in the mitochondria.
- Endoplasmic recticulum (or ER): provides sites (to ribosomes) for protein synthesis (rough ER) and is also responsible for lipid metabolism, detoxification and carbohydrate metabolism (smooth ER).
Hope this helps.
