-

Chlorophyll
-
B.
The sunlight
-
C.
Choloroform
-
D.
Stomata
Correct Answer:
A. Chlorophyll
Explanation:
Chlorophyll is the primary pigment found in the green leaves of plants and is essential for photosynthesis. Located within the thylakoid membranes of chloroplasts, chlorophyll absorbs light energy from the sun—specifically red and blue wavelengths—and uses it to initiate chemical reactions. This energy allows the plant to convert water and carbon dioxide into glucose, which serves as food for the plant, and oxygen, which is released as a byproduct. While other structures like stomata facilitate gas exchange and sunlight provides the necessary energy, chlorophyll is the specific substance responsible for capturing that light to drive the process.
