photosynthesis/respiration
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 |
