| Leewenhoek | cloth merchant used microscope to examine living things |
| Hooke | Named cells |
| Brown | 1700's discovered nucleus |
| Schwann | 1830's german zoologist "all animals are composed of cells |
| Schleiden | Botonist , plants tissus ,"All plants are composed of cells" |
| Virchow | "Omuis cellu la ex cellulae" all cells come from cells |
| What does the cell theory state ? | 1. All living things are composed of cells . 2. The cell is a unit of structure and function of living things 3. All cells come from pre existing cells , |
| Decribe prokaryotic cells , Give example . | doesn't have a nucleus , no chloroplasts (*Bacteria ) |
| What is ment by surface to volume ratio ? | Things evering the cell will be equally distributed by what is outside , to be equal . |
| why is surface to volume ratio important ? | need area to volume so things can get in and out to survive . |
| What do contractile vacuoles do ? | Organell that take up excess water in cell body and contracts to expel water through a pour |
| (F) cell membrane | protect it from environment |
| cell wall | protects it from environment |
| Ribosomes | site of protein synthesis |
| Mitochodria | Produces energy (respiration) |
| Plastids | Membrane bound storage |
| Chloroplasts | Convert sunlight to ATP |
| cristae | floded membrane (repiration ,ATP) |
| Endoplasmic reticulum | membrane lined tunnels transports materials |
| Lysosome | digestion in cells |
| Nucleolus | assembly site of protein and RNA |
| Golgi Apparatus | Sorts pagages and ships proteins |
| Cilia & Flagella | function in movement , made of micro tubles |
| spindle fibers | made of microtubles |
| Centriole | involved in production of repiration |
| Microtubles | made of tublin |
| Microfiliments | made of actin |
| Chromatin | in the nucleus , DNA , Protein |
| cell coat | immune system , recognition proteins |
| vacuole | stores acid sugar iorns and toxins |
| Decribe differnces between Prokaryotic and a Eukaryotic cell ? | (P)-No, distinct nucleus , bare DNA , (plasmid ) no membrane bound organells DO have ribosomes . (E) nucleus membrane bound organells |
| decribe structure of cell membrane . | Bilipid layer with protein , semipermiable |
| diffusion | release of cells |
| osmosis | diffusion of one substance through a membrane |
| Active Transport | with energy |
| Hypotonic | more water under outside cell then inside |
| Isotonic | equal concentration of water |
| Hypertonic | more water in the cell then out |
