(a) Describe the effect on chlorophyll-containing photosystems when the chlorophyll molecules absorb photons of light.
ExtremeBDS [4]

Answer:

Photosynthesis begins in chlorophyll-containing photosystems.

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.

A 'Longitudinal Study' is the one in which the data is fetched from a single source multiple times but at different instances.
