Cells EOC Review
Cell theory , cell organelles , cell transport
| Question | Answer |
|---|---|
| nucleus | controls the cell's activities ; holds DNA |
| nucleolus | dark area in nucleus ; makes ribsosomes within the nucleus |
| lysosome | has digestive enzymes for dissolving worn-out cell parts, food particles and foreign invaders |
| Rough ER | part of ER that makes proteins |
| Smooth ER | part of ER that makes lipids and detoxes the cell |
| cell membrane | selectively allows some particles to move enter & exit the cell |
| vacuole | used for storage of water, food, waste (is much larger in plant cells) |
| cell wall | made of cellulose ; provides support and structure for plant cells |
| mitochondria | makes chemical energy (ATP) ; powerhouse of the cell |
| golgi | sorts, modifies, packages and transports proteins |
| chloroplast | only in plant cells ; makes sugar by photosynthesis |
| centriole | only in animal cells ; helps separate chromosomes during cell division |
| ribosome | makes proteins (can be "free" or attached to RER) |
| cell theory | states that all cells come from pre-existing cells, cells are the building blocks of life & all organisms are made of cells |
| prokaryotic | cell without a nucleus or membrane bound organelles ex. bacteria |
| eukaryotic | cell with a nucleus and membrane bound organelles ex. plant and animals |
| cytoplasm | watery, jell-like fluid that fills the cell and holds the organelles |
| unicellular | means 1 cell organism |
| multicellular | means 2 or more cells organism |
| DNA, cytoplasm, cell membrane, ribosomes | 4 things found in all cells |
| flagella | long tail that allows bacteria cells and sperm cells to move around |
| chromatin , chromosomes (DNA) | holds genetic information |
