What pigment captures the energy in light during photosynthesis?
A
chlorophyll
B
cell wall
C
mitochondria
D
vacuole
Explanation: 

Detailed explanation-1: -Chlorophyll, the primary pigment used in photosynthesis, reflects green light and absorbs red and blue light most strongly. In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll.

Detailed explanation-2: -Chlorophyll’s job in a plant is to absorb light-usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar.

Detailed explanation-3: -Within the thylakoid membranes of the chloroplast is a light-absorbing pigment called chlorophyll, which is responsible for giving the plant its green color. During photosynthesis, chlorophyll absorbs energy from blue-and red-light waves, and reflects green-light waves, making the plant appear green.
