| A | B |
|---|
| Cell Membrane | Controls what goes in and out of the cell. It semi-permeable because only certain things get through |
| Cytoplasm | a gel like liquid found inside the cell membrane that contains things needed by the cell |
| Chloroplasts | contains a green pigment called chlorophyll. They make the leaves of the plant green. |
| Cell Wall | found only in the plant and provides support and protection |
| Mitochondria | supplies most of the energy. Cells that work harder need more mitochondria |
| Nuclus | control center of the cell |
| Vacuole | sac in the cytoplasm that stores water, food and other materials |
| Ribosome | small organelle where proteins are made from amino acids |
| Lysosome | special vesicle that digest food particles, wastes, and foreign invaders |
| Endoplasmic Reticulum | Membrane-covered organelle that produces lipids, breaks down drugs and other substances, and packages proteins for delivery out of the cell. |
| Plant cell has only | Cell Wall and Chloroplasts |
| Found on both Plant and Animal Cells | Cell membrane, Nucleus, Ribosomes, Mitochondria, Golgi Bodies, Lysosomes, Endoplasmic Reticulum, Vacuoles |
| Active Transport | Involves energy to move molecules |
| Passive Transport | no energy in required to move molecules |
| Diffusion | molecules moving from an area of high concentration to low concentration |
| Osmosis | Movement of water from high concentration to low concentration |
| Cells divide | in order to replace old cells that have died and to allow growth |
| Mitosis | a process in which a cell passes on copies of DNA to its daughter cells. |
| Stages of Mitosis | Prophase, Metaphase, Anaphase, Telephase |
| Prophase | DNA and protein forms, chromosomes move to opposite side of the nucleus, chromosome duplicate, and cytoplasm form spindles |
| Metaphase | Double chromosome line up in the middle of the spindles |
| Anaphase | Doubled chromosomes seperate. Single chromosomes move to opposite ends of the spindle |
