Animal Cells

Animal cells are found within every animal. The main difference between an animal cell and a plant cell is that animal cells are not able to make their own food. There are trillions of cells in the animal body and each one is different depending on its function and type. Most animal cells have at least the three main parts: nucleus, cell membrane, and cytoplasm.

The nucleus of the cell gives the cell direction. It directs all activity of the cell. You can think of the nucleus as the brain of the cell for without it, the cell could not function. The nucleus has the ability to make other cell organelles as needed. The nucleus of animal cells is bound by a membrane.

Cell membranes protect animal cells. They keep harmful objects out of the cell and allow helpful objects to enter. You can think of the cell membrane as a guard for the cell.

Cytoplasm is what fills the majority of an animal cell. It helps give the cell shape and keeps organelles in their correct place. When organelles need to transport materials around the cell, cytoplasm allows this process to occur smoothly. It also helps to break down cell waste.
