Photosynthesis takes place in the presence of chlorophyll and _________.
sunlight
The correct answer is sunlight.
Photosynthesis is the process by which green plants and some other organisms convert light energy into chemical energy. The overall reaction can be summarised as:
\[6CO_2 + 6H_2O \;\xrightarrow{chlorophyll,\;sunlight}\; C_6H_{12}O_6 + 6O_2\]
Photosynthesis requires four essential inputs: carbon dioxide, water, chlorophyll and sunlight. Since the question already specifies chlorophyll, the missing partner among the given options is sunlight, which supplies the energy absorbed by chlorophyll in the chloroplasts. Water and carbon dioxide are consumed as raw materials, and "nutrients" is too vague to describe the direct energy input needed for the light reactions.
