| ORGANELLE | LOCATION | DESCRIPTION | FUNCTION |
| cell wall | plant, not animal | *outer layer *rigid, strong, stiff *made of cellulose |
*support (grow tall) *protection *allows H2O, O2, CO2 to pass into and out of cell |
| cell membrane | both plant/animal | *plant - inside cell wall *animal - outer layer; cholesterol *selectively permeable |
*support *protection *controls movement of materials in/out of cell *barrier between cell and its environment *maintains homeostasis |
| nucleus | both plant/animal | *large, oval | *controls cell activities |
| nuclear membrane | both plant/animal | *surrounds nucleus *selectively permeable |
*Controls movement of materials in/out of nucleus |
| cytoplasm | both plant/animal | *clear, thick, jellylike material and organelles found inside cell membrane | *supports /protects cell organelles |
| endoplasmic reticulum (E.R.) |
both plant/animal | *network of tubes or membranes | *carries materials through cell |
| ribosome | both plant/animal | *small bodies free or attached to E.R. | *produces proteins |
| mitochondrion | both plant/animal | *bean-shaped with inner membranes | *breaks down sugar molecules into energy |
| vacuole | plant - few/large animal - small |
*fluid-filled sacs | *store food, water, waste (plants need to store large amounts of food) |
| lysosome | plant - uncommon animal - common |
*small, round, with a membrane | *breaks down larger food molecules into smaller molecules *digests old cell parts |
| chloroplast | plant, not animal | *green, oval usually containing chlorophyll (green pigment) | *uses energy from sun to make food for the plant (photosynthesis) |
