| The cell wall is found in plant cells, but not in animal cells. This is the outermost layer in the plant cell. It is stiff, rigid, nonliving, and made of cellulose. It provides support so that the plant can grow tall and protection. Some materials like water, oxygen, and carbon dioxide can pass through it.[image] |

The cell membrane is found in both plant and animal cells. It is the outermost layer in the animal cell and is found just inside the cell wall in the plant cell. It has pores and is selectively permeable allowing the movement of certain substances into and out of the cell. The cell membrane also protects and supports the cell. |
