Question

How much is the percentage of solar radiation absorbed by all the green plants for the process of

photosynthesis ?


​

Answer 1

Answer:

It is the part of electromagnetic radiation that can be used as the source of energy for photosynthesis by green plants. Percentage of photosynthetically active radiation (PAR) that is captured by plants in synthesis of organic matter is about 1-2 % of incident solar energy.

Answer 2

Answer:

Most solar energy occurs at wavelengths unsuitable for photosynthesis. Between 98 and 99 percent of solar energy reaching Earth is reflected from leaves and other surfaces and absorbed by other molecules, which convert it to heat. Thus, only 1 to 2 percent is available to be captured by plants.
