|---|
| 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 |
| vesicles | transport sacs that move material through the cytoplasm |
| cilia | hair-like structures that move the cell |
| flagella | tail like structure that moves a cell |
| rough er | transports proteins made by the ribosomes |
| smooth er | break down toxins, create lipids and |
| centrioles | Structures that produce spindle fibers that move chromosomes |
| microtubules | Hollow tubes that makeup cilia and flagella |
| microfilaments | Tiny, solid tubes that move materials within the cell |
| peroxisome | Type of vesicle that contains enzymes that break down peroxide |
| leucoplast | A type of plastid that stores starch |
| chromoplast | A type of plastid that stores red, yellow and orange pigments |
| chromatin | Chromosome form where they are thin and stringy. |
| plasmid | Round DNA found in a bacterium that is used by humans for genetic engineering. |
| pili (pilus) | Small projection that helps bacteria attach to surfaces. |
| capsule | Thick cover on a bacterium that allows the bacterium to go dormant. |
| cytoskeleton | All of the interconnecting fibers, tubules and threads that allow to change shape and move. |
| cytoplasm | The jelly-like substance that stores disolved substances and wastes |
