Answer:
c. sunlight
Explanation:
Chlorophyll is a green pigment found in the plants present in the organelle known as chloroplasts.
Chlorophyll is important for photosynthesis as it allows the plants to absorb the energy from the sunlight.
Sunlight is an essential factor for photosynthesis to occur because it is the energy derived from the sunlight that helps the plants to carry out the photosynthetic reaction to make food.
The reaction is as follows :
6CO2 + 6H2O ---sunlight---> C6H12O6 + 6O2.
carbon dioxide + water -----sunlight---> glucose + oxygen
