Photosynthesis and Respiration
Question | Answer |
---|---|
Autotroph | an organism that can create its own food Ex. plants |
Heterotroph | an organism that relies on other organisms to make their food Ex. humans and animals |
Chlorophyll | a green pigment in the chloroplasts |
Stomata | an opening on the underside of the leaf that lets out oxygen and takes in carbon dioxide |
Photosynthesis | uses sun |
Photosynthesis Stage 1 | the plant captures the sun energy by absorbing the energy into the chlorophyll |
Photosynthesis Stage 2 | the cell uses the energy to create oxygen and energy |
Photosynthesis Equation | 6 CO2 + 6 H2O uses yield C6H12O6 + 6 O2 |
Respiration | cells break down the carbohydrates and release the energy inside of them |
Respiration Stage 1 | in the cytoplasm, molecules of glucose break down into smaller molecules |
Respiration Stage 2 | in the mitochondria, the smaller molecules use oxygen to further break down and release energy |
Respiration Equation | C6H12O6 + 6 O2 uses yield 6 CO2 + 6 H2O |
Fermentation | when the body can't supply the cells oxygen anymore, fermentation supplies the cells with energy without using oxygen |
2 kinds of fermentation | Alcoholic and Lactic Acid |
