Question

(a) Describe the effect on chlorophyll-containing photosystems when the chlorophyll molecules absorb photons of light.

(b) Identify an appropriate control that the researchers should use when they study the growth and photosynthetic ability of the plant with the mutant enzyme.
(c) Scientists claim that a plant that has more than one type of photosynthetic pigment has greater fitness than a plant that has only one type of photosynthetic pigment. Provide reasoning to justify this claim.

Answer 1

Photosynthesis begins in chlorophyll-containing photosystems.

Step-by-step explanation:

Photosynthesis begins in chlorophyll-containing photosystems when the chlorophyll molecules absorb photons of light. This energy passes through other chlorophyll molecules, towards the reaction center of Photosystem II. The researcher should use plant with normal enzyme as a control with a plant having mutant enzyme. A plant that has multiple photosynthetic pigment has greater fitness as compared to plant that has only one type of photosynthetic pigment because multiple pigments absorb different wavelengths of light that allows the plant to capture the maximum amount of energy from the sun for photosynthesis.
