photosynthisis and resperation card
| Question | Answer |
|---|---|
| autotroph | an organism that makes it's own food/ energy (Independent) I.E. Plants |
| Heterotroph | an organism that depends on other organisms to supply their energy/ food (dependent) I.E. Humans and animals |
| Chlorophyll | a green pigment in the chloroplasts |
| Stomata | opening in the underside of a leaf. lets out oxygen and brings in carbon dioxide. |
| photosynthisis | the process in which a plant captures energy from the sun - chlrorphyll absorbs the energy in the chloroplasts - (Stage one) and uses energy, carbon dioxide, and water to make sugars for energy/ food and oxygen (stage two) |
| Carbon Dioxide + Water -----> Light energy = sugar + oxygen | photosyntisis formula, oppisite for respiration |
| Respiration | Cells break down sugars and release the energy |
| Stage one | In cytoplasm molecules of glucose are broken down into smaller molecules |
| Stage two | in the mitochondria, the smaller molecules use oxygen to further break down the molecules which release energy |
| Respiration formula | Sugar + Oxygen -----> Light energy = Carbon Dioxide + water |
| Fermentation | when the body can't supply the cells oxygen anymore, this supplies the cells without sing oxygen There are two types Alcoholic and lactic Acid |
| Where does Alcoholic Fermentation occur? | in yeast |
| where does lactic acid Fermentation occur? | In Muscles |
