| cell wall | The cell wall is made up of nonliving material that supports and protects and it is only found in the plant cell. |
| cell membrane | the cell membrane acts like a door of cells it comes next after the cell wall, found in both plant and animal cells, it lets good materials in and wastes out |
| nucleus | the nucleus acts as the brain of the cell and it controls the activties of the cell |
| E.R | transports all proteins around to the parts of the cell that need them |
| ribosomes | many of them attach to the inner lining of the E.R and it is the protein making site of the cell |
| mitochondria | they are called ''Power Houses'' because they supply most of the energy for the cell. |
| vacuole | storage places for food and materials for the cell |
| lysosome | are involved with the digestive activities |
| chloroplasts | only found in plants cells; provide the green pigment chlorophyll for plants to make their own food and maintain their color |
| chromosomes | humans have 23 pairs of these; found in the nucleus and contains a person's genetic code |
| nuclear membrane | surrounds and protects the nucleus, allows good materials into the nucleus and wastes out |
| tissues | groups of cells make up these |
| organs | groups of tissues make up these |
| organ systems | groups of organs make up these |
| organism | a group of organ systems makes up these |
