Bio Organelles
Quiz on 10-20-05
| Organelle Name | Function | Structure | Picture |
|---|---|---|---|
| Cytoplasm/Cytosol | contains all organelles | geltain-like fulid | 1 |
| Nucleus | where nucleic acids are synthesized and activites of cell are directed | surrounded by the nuclear envelope | 7 |
| Ribosomes | synthesis proteins | large complex of protein and RNA | 2 |
| Cell Wall | suports/protects cell and has pores | made of long chains of cellulos | 15 |
| Smooth ER | biosynthesis of macromolecules used to construct other organelles and involved with lipid metablism/detoxification | membrane continuous with outer membrance of nucleus | 10 |
| Golgi Apparatus | director of traffic | composed of sets of smooth surfaced cisternaeL located near the nucleus | 8 |
| Mitochondria | responsible for carrying out aerobic respiration | double membrane, folded into cristaes, mixture of enzymes | 14 |
| Lysosomes | involved with lipid metablism/detoxification | sacs filled with 40 different enzymes | 3 |
| Chlorplasts | contains chlorophyll for photosynthesis/found in green of plants | vary in structure but all are membranc-bound organelles | 11 |
| Chromoplasts | synthesize/stores pigments | vary in structure but all are membranc-bound organelles | 20 |
| Leuoplasts | stores food and found in most plants(root of plants) | vary in structure but all are membrane-bound organelles | 19 |
| Rough ER | used to constrcut other organelles and abundant in celll for protein secretion | membrane is continuous with the outer membrance of nucleus, ribosomes | 9 |
| Microtubules | make up part of cytoskeleton; aid in movement of chromosomes in cell division | slender prootein tubes | 4 |
| Microfilaments | make up part of cytoskeleton; cytosplamic streaming | fine protein threads | 5 |
| Cilia | helps movement of cells, and is also found in female reproductive system | cross section which shows 9 pairs of microtubules and short hair-like extensions which cover cell | 13 |
| Flagella | helps movement of cells, and is also found in female reproductive system | cross section which shows 9 pairs of microtubules and long whip-like structures occuring in pairs or singly | 6 |
| Nucleolus | synthesize ribosomes | structure found within the nucleus | 18 |
| Cell Membrane | supports/protects cell | lipid bilayer | 17 |
| Vacuole | store water, waste products and enzymes | fluid filled sac-like structure | 12 |
| Nuclear Envelope | allows structure that allows RNA to pass in and out | has pores that allow molecules in and out of nucleus(such as RNA) | 16 |
