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) |
