| Excretion | removal of soluble waste materials |
| Secretion | release of biosynthesized substances |
| Homeostasis | maintaining the status quo |
| Reproduction | producing more cells |
| Cytology | study of cells |
| Cell Wall | rigid structure on the outside of certain cells, usually plant and bacteria cells |
| Middle lamella | thin film between the cell walls of adjaeent plant cells |
| Plasma Membrane | semipermeable membrane between the cells contents and either the cell wall surrounding |
| Cytoplasm | jelly like fluid inside the cell in which the organelles are suspended |
| Ions | substances in which at least one atom has an imbalance of protons and electrons |
| Cytoplasmic streaming | motion of cytoplasim in a cell that result in a cordinated movement of the cells contents |

| Waste vacuole | contains waste products of digestion |
| Pinocytic Vesicle | formed at the plasmamembrane to allow the absorption of large molecules |
| Golgi bodies | organelles where proteins & lipids are stored and modified |
| Nulclear membrane | highly porous membrane that seperates the nucleus from cytoplasm |
| Chronmatin | Clusters of DNA, RNA & proteins in the nucleus |
