Cell organelles
Unit 1&2 VCE Biology
| Term | Definition |
|---|---|
| flagella | whip-like structure, allows cell to move |
| prokaryote | primitive form of cell, does not contain a nucleus or membrane-bound organelles, eg bacteria |
| cytoplasm | everything between plasma membrane and nucleus (cytosol plus organelles) |
| vacuole | store food/nutrients/water for cell |
| cilia | slender organelles that project from cell body and either help the cell to move or help it to sense its surroundings |
| cytosol | fluid component of cytoplasm |
| nucleus | control centre of cell, contains DNA/chromosomes |
| smooth endoplasmic reticulum | site where lipids and steroids are produced |
| chloroplast | site of photosynthesis, produces glucose |
| vesicle | transports substances around, into and out of cell |
| lysosome | digest excess/worn-out organelles, food and bacteria and viruses |
| ribosome | site of protein synthesis |
| golgi body/apparatus/complex | protein is modified and packaged for transport/export |
| mitochondria | site of aerobic cellular respiration, produces ATP |
| eukaryote | complex form of cell, contain a nucleus and membrane-bound organelles, eg muscle cell |
| plasma/cell membrane | membrane surrounding cell, controls entry and exit of substances |
| cell wall | surround plant, fungi and bacteria cells, provides structural support for cell |
| DNA | deoxyribonucleic acid - genetic material of a cell |
| cytoskeleton | provides structure and support to cell, acting as skeleton |
| rough endoplasmic reticulum | protein is folded here and transported from ribosomes to golgi apparatus |
