Photosynthesis is the process plants, algae and some bacteria use to turn light energy into chemical energy. It takes place mainly in the chloroplasts of leaf cells, where the green pigment chlorophyll absorbs mostly red and blue light. In the light-dependent reactions, which happen in the thylakoid membranes, water molecules are split, releasing oxygen as a by-product and producing ATP and NADPH. In the Calvin cycle, which takes place in the stroma, the enzyme RuBisCO fixes carbon dioxide from the air, and ATP and NADPH are used to build a three-carbon sugar that the plant turns into glucose. The overall equation is 6CO2 + 6H2O + light energy → C6H12O6 + 6O2. Light intensity, carbon dioxide concentration and temperature can all limit the rate of photosynthesis.
Question 2From sentence 2
Where does photosynthesis take place mainly in leaf cells?
- In the cell membrane of leaf cells
- In the mitochondria of leaf cells
- In the nucleus of leaf cells
- In the chloroplasts of leaf cells
Question 5From sentence 3
What is released as a by-product when water molecules split during the light-dependent reactions?
- Oxygen
- Glucose
- Water vapor
- Carbon dioxide
Question 8From sentence 4
What role does RuBisCO have in the Calvin cycle?
- It absorbs red and blue light.
- It splits water molecules.
- It converts light directly into glucose.
- It fixes carbon dioxide from the air.
