Biology Question on Photosynthesis in higher plants
Which of the following absorb light energy for photosynthesis
A
Chlorophyll
B
Water molecule
C
O2
D
RUBP
Answer
Chlorophyll
Explanation
Solution
The correct option is (A): Chlorophyll
A substance that absorbs a certain visible light wavelength is known as a pigment. Plants need chlorophyll, a green pigment found in thylakoid membranes of chloroplasts, for photosynthesis. Green plants use the energy of light to transform carbon dioxide (CO2) and water (H2O) into carbohydrates, a process known as photosynthesis. The plant's photosynthetic pigment, chlorophyll, absorbs light energy while air containing carbon dioxide and oxygen enters the plant through the stomata on the leaves.
