Cell function/job
| Question | Answer |
|---|---|
| Cell wall | made of cellulose in plants, made of chitin in fungi. gives cell structure, keeps cell from bursting. NOT IN ANIMAL CELLS AND SOME PROTISTS CELLS. |
| cell membrane | lets some things in and out (selectivly permiable). controls what goes in and out of the cell. |
| Cytoplasm | in eukariatic cells, jelly like substance. cytosol + organells= cytoplasm. mostly water. |
| nucleus | enclosed in double membrane. controls all the of the cells activity.Only in Eukaryotic cells |
| Neclear enevelope | protects neucleus. pores allow matetials to move in and out of neucleus. |
| Chromatin | thin strands of DNA and protein contains genitic code for directing cells activities. |
| Necleolus | makes ribosomes |
| Cloroplasts | oval shapped,has green sacs double membrane contains chlorophyll. found in pants and some Protist cells |
| Mitochondria | oval shaped Cellular resperation. double membrane, tiny folds in second membrane. |
| Ribosomes | small roundish made of RNA and proteins some in cytoplasm and some are on the rough ER |
| Endoplasmic Reticulum | Rough ER: series of membrane bound passage ways dotted with ribosomes Smooth ER Does not have Ribosomes |
| Golgi bodies | flattened out sac and tubes. can pinch of little ventricles that carry chemicals. Receive Protiens from ER. packages them and sends them out |
| Vacuole | water filled sac, larger in plant cells store food and waste and other mateials |
| Lysosmes | contains enzymes that break down food particles or cell parts ( clean up crew) |
