Question

based on a variety of experiments, it is known that the rate of photosynthesis is highest when wavelengths of light between 400 and 500 nm are used, and when wavelengths around 700 nm are used. what does this indicate about the relative importance of chlorophyll a and b in photosynthesis? multiple choice chlorophyll a and b are much less important than other pigments in the reflection, absorption and transmission of light relevant to photosynthesis reflection of light by chlorophyll a and b is essential for the process of photosynthesis transmission of light by chlorophyll a and b is essential for the process of photosynthesis absorption of light by chlorophyll a and b is essential for the process of photosynthesis

Explanation:

Chlorophyll a and b absorb light in the 400 - 500 nm range and this is when photosynthesis rate is high. Absorption of light by these pigments provides the energy needed for photosynthesis. Reflection and transmission do not provide energy for the process, and there is no indication from the given information that they are less important than other pigments.

Answer:

Absorption of light by chlorophyll a and b is essential for the process of photosynthesis
