Question

Approximately what percentage of solar energy falling on a plant is assimilated in photosynthesis?

Answer 1

`1%`

Explanation:

Out of all the sunlight energy that falls on a plant, only `1%` is absorbed by the photosynthetic pigments. This energy is then converted into chemical energy in order to form sugars in dark reactions of photosynthesis. The remaining `99%` of solar energy is reflected or transmitted which is then used to evaporate water, heat up soil etc...
