The intensity of light is more important than leaf surface area for photosynthesis.
a. true
b. false

Option A. True

Explanation:

Photosynthesis is the process by which most plants, algae and some other organisms synthesize their own food in the presence of sunlight, water and carbon dioxide.

Primary factors on which photosynthesis depends are-

Intensity of light

Concentration of Carbon dioxide

Temperature

Water

The intensity of light is directly proportional to the rate of photosynthesis, which means higher the intensity of light higher will be the photosynthesis.

Therefore, the right answer is "Option A".
