endocytosis | goes in |
exocytosis | goes out |
Phagocytes | cells that protect body by ingesting harm |
prokaryotsis | before nut. Bacteria, Algae, Glucose |
Eukaryoles | true nut (nucleus) |
Hypertonic | high osmosis pressure, water loss |

MEOSIS | me egg sperm only takes place for gametes |
cell membrane | thin membrane permeable |
nuculeus | site of ribosone production |
cytoskelton | forms supportive frame work made of protein rods n tubles |
cytoplasm | plasm has em.. supports n protects organelles. liquid around nuculus |
