Detailed explanation-1: -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-2: -The light-dependent reaction takes place within the thylakoid membrane and requires a steady stream of sunlight, hence the name light-dependent reaction. The chlorophyll absorbs energy from the light waves, which is converted into chemical energy in the form of the molecules ATP and NADPH.

Detailed explanation-3: -Chlorophyll absorbs the sunlight for photosynthesis.

Detailed explanation-4: -Chlorophyll role is to absorb light from sunlight in plants. The energy absorbed from light is utilized to convert carbon dioxide and water molecules into glucose, through photosynthesis. Chlorophyll being a primary pigment (photoreceptor) reflects green light, absorbing red and blue light in the chloroplast.

Detailed explanation-5: -Because they interact with light to absorb only certain wavelengths, pigments are useful to plants and other autotrophs–organisms which make their own food using photosynthesis. In plants, algae, and cyanobacteria, pigments are the means by which the energy of sunlight is captured for photosynthesis.
