| the basic unit of living things |
| eukaryotic cells- contains a nucleus and organelles |
| prokaryotic cells- conatains no nucleus and is more primative; bacteria |
| organelles |
| "tiny organs" or structures in the cell that keep it living |
| cell wall |
| made of cellulose for support and protection of plant cells; also found in bacteria |
| cell membrane |
| semi-permeable; controls what goes into and out of the cell |
| cytoplasm |
| "the gel in the cell that contains the organelles" |
| mitochondria |
| the energy producers of the cell; "powerhouses" |
| chloroplasts |
| found in plant cells, contain chlorophyll (green) that makes food from sunlight, carbon dioxide and water (photosynthesis) |
| ribosomes |
| small dotlike structures that make protein |
| lysosomes |
| round structures that break down materials for the cell |
| Golgi bodies or apparatus |
| flattened tubes or sacs that "repackage" food for use in the cell |
| nucleus |
| the control center of the cell; surrounded by the nuclear envelope that is porous |
| nucleolus |
| small dark center of the nucleus that makes ribosomes |
| chromatin |
| the genetic material in the nucleus that controls the cell (DNA - deoxyribonucleic acid) |
| endoplasmic recticulum - channels or tunnels through the cytoplasm used for transporation of proteins an dother materials in the cell (smooth ER - no ribosomes) (rough ER - contains ribosomes) |
| vacoules |
| storage areas for food, water, and some wastes (larger and fewer in plant cells) |
| Virus |
| nonliving particle with genetic material and a protein coast that requires a host cell to infect and reproduce |
| Protist |
| a kingdom living organisms that are animal like, plant like, or fungi like; most are unicellular |
| Fungi |
| a eukaryotic organism that lives on dead and decaying material |
