Question

which statement about chlorophyll is true? chlorophyll appears green because it absorbs green light. chlorophyll is absent from light - harvesting complexes, also known as antenna systems. chlorophyll contains fe²⁺. most of the chlorophyll in a plant participates in an oxidation - reduction reaction. most of the chlorophyll in a plant functions to gather light.

Explanation:

Chlorophyll appears green because it reflects green light, not absorbs it. It is a key component of light - harvesting complexes. It contains Mg²⁺, not Fe²⁺. Only a small amount of chlorophyll participates in oxidation - reduction reactions, while most functions to gather light energy for photosynthesis.

Answer:

Most of the chlorophyll in a plant functions to gather light.
