| A | B |
| cell wall | 1 support (grow tall) 2. protection 3. allows H20, O2, CO2 to pass into and out of cell |
| cell membrane | 1. support 2. protection 3. controls movement of materials in/out of cell 4. barrier between cell and its environment 5. maintains homeostasis |
| nucleus | controls cell activities |
| nuclear membrane | contorlsmovement of materials in/out of neucleus |
| cytoplasm | supports/protects cell organelles |
| endoplasmic reticulum (ER) | carries materials through cells |
| ribosome | produces proteins |
| mitochondrion | breaks down sugar molecules into energy |
| vacuole | store food, water, waste (plants need to store large amounts of food |
| lysosome | 1. breaks down larger food molecules int smaller molecules 2 digests old cell parts |
| chloroplast | uses energy from sun to make food for the plant (photosynthesis) |
