The part of the chloroplast that absorbs lights is called ____
A
Thylakoid
B
Grana
C
Stroma
D
Chlorophyll
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: -Chlorophyll is the photosynthetic pigment. Violet-blue and Orange-red light wavelengths are absorbed by chlorophyll A. The rate of photosynthesis is more in blue and red light.
