Question

Explain why temperature has little influence on the absorption of light by photosynthetic organisms. (2)

a) Photosynthetic organisms are not affected by temperature changes.
b) Temperature affects the color of photosynthetic organisms.
c) Temperature does not affect the availability of photons for photosynthesis.
d) Photosynthetic organisms have built-in temperature regulators.

Answer 1

Temperature does not directly influence the absorption of light by photosynthetic organisms. Photosynthetic organisms have pigments that allow them to absorb energy from a wider range of visible-light wavelengths, which is crucial for photosynthesis. While temperature can affect the physiology and growth of organisms, it does not affect the availability of photons for photosynthesis.

Step-by-step explanation:

Temperature does not affect the availability of photons for photosynthesis. Many photosynthetic organisms have a mixture of pigments that allow them to absorb energy from a wider range of visible-light wavelengths. The ability to absorb light is crucial for photosynthesis, and while temperature can affect the physiology and growth of organisms, it does not directly influence the absorption of light during photosynthesis.
