photosynthesis/cellular respiration

1. What is chlorophyll and how does it help plants?

• A.Chlorophyll is a pigment that absorbs light energy and makes glucose.

• B.Chlorophyll is a protein that changes shape in the presence of sunlight.

• C.Chlorophyll is a receptor that binds carbon dioxide when energized by light

• D.Chlorophyll is an enzyme that catalyzes the production of glucose when exposed to light.
