cell theory, cell types, cell structures
| Term | Definition |
|---|---|
| what do all cells posses? | contains dna, contains rna, contains ribisomes, filled with cytopasm, surroned by cell membrane |
| cell membrane | controls what ebnters and exits the cell bhelps maintian homestasis |
| nuclecus | membrane bound controls cell funtions, contains dna makes ribosomes |
| nucleous | makes ribisomes |
| mitochondria | membrane bound tranforms engergy in food to engery that the cell can use |
| ribisomes | bulds protein based on gentic code found in all cells |
| vesicles | membrane bound storgae, packeges stuff to move around in/out of cells |
| vacuoles | membrane bound storgae, packeges stuff to move around in/out of cells |
| lysosome | membrane bound stores digestive enzeymes to clean and recycle within the cell |
| rough e.r | membrane bound processes an breaksdown |
| smooth e.r | membrane bound processes and breakdown toxins and makes lipids |
| golgi appartaus | membrane bound packages proteins |
| cytoplasm | jelly like fluid |
| cytoskelteon | provides support for cell, tranport nd moverment |
| cell wall | rigid outer lyer of many cells |
| chloroplast | membrane bound where photosynthesis takes place, in eukaryotes |
| centrioles | participates in cell divison'(only animal cells) |
| cell theory 1 | 1. all organisms are made of one or more cells |
| cell theory 2 | cells are the basic units of structure and function in living things |
| cell theory 3 | cells come from prexistings cells |
| prokaryotic cells | no nucleus but has genitic material, no mebrane bound organleles, all types of bactria |
| eukatyotic cells | has a uvleus with dna inside, has organelles and internal membranes,highly specilized |
