During a year,plants never use 100% of the incoming solar radiation for photosynthesis.What is a reasonable explanation for this?
I.Plants cannot photosynthesize as well during winter (in cold winter climates).
II.Plants cannot photosynthesize as well on cloudy days.
III.The pigments that drive photosynthesis respond to only a fraction of the wavelengths that are available.

Question

Quizplus · Accepted Answer

All three options are correct reasons why plants cannot use 100% of the incoming solar radiation for photosynthesis. Plants may not be able to photosynthesize well during winter or on cloudy days, resulting in reduced photosynthetic activity. Additionally, the pigments responsible for driving photosynthesis only respond to certain wavelengths of light and cannot use all the available solar radiation. Therefore, option D is the best choice.
