cell organelles
| Term | Definition |
|---|---|
| cytoplasm | semisolid substances making up the interior of the cell |
| golgi body | regulates the secretion of products out of the cell - post office |
| chloroplast | structures found only in plant cells - function in the production of food b the plant |
| nucleus | controls the activities of the cell |
| centrioles | found almost exclusively in animal cells - functions in the process of cell division |
| ribosomes | specific sites of protein synthesis |
| chromosomes | composed of DNA - carries the hereditary information of the cell |
| cell wall | found only in plant cells - rigid structure that gives support and protection to the cell |
| mitochondria | energy storehouse - sit in the cell where energy is stored |
| endoplasmic reticulum | "assembly line" of the cell - a network of tubes providing the cell with an internal transport system |
| cell membrane | regulates the passage of water and dissolved substances into and out of the cell |
| nuclear membrane | a double membraned structure opening to the E.R - regulates the passage of materials between the nucleus to the cytoplasm |
| cytoskeleton | composed of microtubules and microfilaments gives structure to the interior of the cell |
| central vacuole | store water (sap) - large structure found within plant cells |
| nuclear pore | openings in nuclear membrane |
| cilia | many small hair-like structures which aid in transportation and movement |
| lysosomes | digestive enzymes - contained within |
| vacuoles | storage compartments found in plant and animal cells |
| flagella | long tail-like structure which aids in movement |
| glycocalyx | cell sweater or coat which helps cells identify each other |
| nucleolus | structure within nucleus - special type of DNA |
| peroxisomes | condensation rxns - contain digestive vacuoles to disable toxins/ poisons |
