Question

The most important role of pigments in photosynthesis is to _____. store energy in glucose molecules screen out harmful ultraviolet rays capture light energy release energy from glucose molecules

(a)- Capture Sun energy
(b)- Capture day light energy
(c)- Capture light energy
(d)- All of the above

Answer 1

The main role of pigments in photosynthesis is to capture light energy, which is used to convert solar energy into chemical energy stored in carbohydrates. Chlorophyll is an example of such a pigment.

Step-by-step explanation:

The most important role of pigments in photosynthesis is to capture light energy. These pigments include chlorophyll, which captures solar energy. Pigments absorb certain wavelengths and reflect or transmit others, which determines their color. The absorbed light initiates the photosynthesis process, where energy from light is transformed into chemical energy within carbohydrates during the Calvin cycle. The photosynthetically active radiation for plants is in the wavelength range of 700 nm to 400 nm. Organisms with a mixture of pigments can absorb a wider range of light wavelengths, making photosynthesis more efficient.

For question 6, the molecule that absorbs the energy of a photon in photosynthesis is chlorophyll.

Answer 2

(c)- Capture light energy

Step-by-step explanation:

The process of Photosynthesis is to prepare chemical energy by the use of light energy from the sun .

The pigment responsible for photosynthesis is Chlorophyll , which is present is the leaves of the plant or tree , which capture the light energy of the sun , and then with the help of the energy and carbon dioxide and water absorbed by the roots , the food of plant is prepared , i.e. , oxygen along with energy .

hence , the correct answer for the given statement is ( c ) .
