| A | B |
| nucleus | the control centre of the cell |
| nucleolus | small circular structure(s) within the nucleus; may be involved in protein synthesis |
| chromosomes | genetic material found in the nucleus |
| mitochondria | where energy in the form of ATP is produced |
| ribosomes | where proteins are made |
| endoplasmic reticulum | transport system in the cell |
| golgi apparatus | packages up protein |
| lysosome | special type of vacuole that breaks down large molecules and cell parts |
| chloroplast | where photosynthesis occurs |
| cell membrane | semi-permeable; it controls what moves in and out of the cell |
| cell wall | protects and supports plant cells |
| eukaryote | cell that has a membrane-bound nucleus |
| prokaryote | a cell with no nuclear membrane and few (if any) membrane bound organelles |
| vacuole | stores wastes, water, food |
| active transport | cell energy is ued to move particles through a membrane |
| passive transport | no cell energy is used to move particles through a membrane |
| diffusion | movement of molecules from a high concentration to a low concentr |
| osmosis | movement of water throgh a membrane from a high concentration to a low concentra |
| equlibrium | molecules are balaced on both sides of the membrane |
| chloroplasts ans cell wall | two organelles in plants that are not in animal cells |
| out of the cell the cell | the way water would move in a cell put in salt water |
| into the cell | the way water would move in a one celled animal put in fresh water |
