Cell Notes
Structure/Function
| Structure | Function |
|---|---|
| Cell Wall | *Animal cells don't have one *Plants: Made of cellulose *Gives strength structure & rigidity to plant through turgor pressure |
| Cell Membrane | *Outside covering *Determines what goes in/out of cell *Flexible but supports cells |
| Vacuole | *Storage unit in cells that hold water *Large in plants, small in animal cells |
| Mitochondria | *"Power house of the cell" *Produces energy (breaks down glucose) * C6H12O6 ---> C)2 + H2O + Energy |
| Cytoplasm | * Gelatinous, semi-transparent fluid that fills the cells *Organelles are suspended in cytoplasm |
| Chloroplast | *Only found in plants *Site of photosynthesis: captures radiant energy and converts it to chemical energy (C6H12O6) AKA-glucose |
| Nucleus | *Control center of cell *Houses DNA *Controls cell growth and makes ribosome |
| Prokaryote | *A single-celled organism with no nucleus *Does have DNA *No other specialized organelles *Eubacteria & Archaebacteria |
| Eukaryote | *Has a nucleus that contains DNA *Single or multicellular *Has membrane bound organelles *Includes all living organisms other than the eubacteria and archaebacteria |
| Cell Theory | *All living organisms are composed of one or more cells *The cell is the most basic unit of life *All cells arise from pre-existing, living cells |
| Golgi Body | *Packages cell products for transport (like UPS) |
| Chloroplast | *Site of photosynthesis: captures radiant energy and converts it to chemical energy (C6H12O6) *Has chlorophyll-green pigment that absorbs light |
