| Question | Answer |
|---|---|
| Autotroph | an organism that CAN make its own food (ex. plant) |
| heterothroph | an organism that CANNOT make its own food (ex. animal) |
| chlorophyll | the main photosyntheticic pigment (green) that captures light energy and uses it to power stage 2 of photosynthesis |
| stomata | small openings on underside of a leaf that lets CO2 enter and O2 exit |
| chloroplast | organelle in plants that contains chlorophyll |
| respiration | the process by which organisms use food and oxygen to make energy stage 1 – cytoplasm stage 2 – mitochondria |
| mitochondria | where stage 2 of respiration takes place. broken down pieces of glucose along with oxygen create a release of energy |
| photosynthesis equation | plants make food from sunlight 6 CO2 + 6 H2O – SUNLIGHT – C6 H12 O6 + 6 O2 |
| respiration equation | C6 H12 O6 + 6 O2 ——-> 6 CO2 + 6 H2O + Energy |
| Water | H2O |
| Glucose | C6 H12 O6 |
| Carbon Dioxide | CO2 |
| Oxygen Molecule | O2 |
|
What happens during photosynthesis? |
Stage 1 – chlorophyll captures light energy from the sun
Stage 2 – light energy transforms water and carbon dioxide into glucose and oxygen |
|
What happens during respiration? |
Stage 1 – glucose is broken down into small molecules in the cytoplasm. tiny amount of energy is released
Stage 2 – broken down glusose along with oxygen enter mitichondria release energy CO2 and H2O |
| Reactants needed for photosynthesis | 6 water (h2o) and 6 carbon dioxide (co2) |
| Reactants for Respiration & Products of Photosynthesis | 1 glucose and 6 oxygen |
| Products of Respiration | 6 carbon dioxide, 6 water and Energy |
