What are some facts about cells

Although there are different types of cells, most cells have the same components. A cell consists of a nucleus and cytoplasm which is contained within the cell membrane. The cell membrane regulates what passes in and out of the cell. Inside every cell are mitochondria. Mitochondria are tiny structures that provide the cell with energy. The main purpose of a cell is to organize. Cells hold a variety of pieces and each cell has a different set of functions. Some cells move throughout the body, like blood cells. Others are attached to one another like muscle cells, and they stay in one place. Some cells, like skin cells, divide and reproduce quickly. Nerve cells, do not divide or reproduce except under usual circumstances.

All living things are made up of cells.

Cells are made up of proteins and organelles.

Groups of cells form tissues and systems.
