Ch.6:Cell Organelles
Cell Organelle Structure & Function
| Question | Answer |
|---|---|
| Provides additional support and protection for plant and bacteria cells | Cell Wall |
| Assist in cell division in animal cells only | Centrioles |
| Contain photosynthetic pigments used in photosynthesis; Plant cells and photosynthetic bacteria and protists | Chloroplasts |
| Surface hairs that brush material across cells | Cilia |
| Liquid matrix between cell membrane and nucleus; organelles are embedded in | Cytoplasm |
| Network of filaments that provide support, give cells shape, and contract to allow cell movement | Cytoskeleton |
| Whip-like "tail" used to move cells | Flagella |
| Modifies, sorts, ad packages proteins that are being exported from cell (pinched off as vesicles) | Golgi bodies |
| Digest unwanted materials (enzymes inside break down toxins etc.) | Lysosomes |
| Location of cellular respiration; "Power house" of cell; provides energy in the form of ATP | Mitochondria |
| Encloses DNA; Eukaryotes only | Nuclear Envelope |
| Dense, darker region of DNA in nucleus where ribosomes are being made | Nucleolus |
| Command or control center of the cell; houses DNA; Eukaryotes only | Nucleus |
| Acts as a boundary between the cell and its environment; regulates traffic in and out of cell | Plasma (cell) membrane |
| Make proteins | Ribosomes |
| Receives and transports proteins made by ribosomes attached to it. | Rough Endoplasmic Reticulum (ER) |
| Synthesizes lipids; no ribosomes attached | Smooth Endoplasmic Reticulum (ER) |
| Membrane-bound sacs that transport materials into and out of cell | Transport Vesicles |
| Stores water and dissolved materials; Huge storage areas in plant cells | Vacuoles |
