Equation for photosynthesis
Carbon + water --------> glucose + oxygen
1 of 10
Explain why chlorophyll is needed in photosynthesis
Chlorophyll absorbs the light energy needed to convert carbon dioxide and water into glucose (chemical energy)
2 of 10
What are the three limiting factors in plants?
Light intensity, carbon dioxide concentration, temperature
3 of 10
What is the glucose used for from photosynthesis?
1 - to release immediate energy through respiration in all plant cells
4 of 10
How do plants produce proteins for growth?
To produce proteins, plants also use nitrate ions that are absorbed from the soil to make amino acids that are then joined to make proteins.
5 of 10
How could you increase the rate of photosynthesis in a greenhouse?
Light bulbs
