Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The role of the Sun during photosynthesis is to serve as a source of-
A
hydrogen atoms
B
radiant energy
C
gravitational pull
D
carbon dioxide
Explanation: 

Detailed explanation-1: -During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.

Detailed explanation-2: -The radiant energy of the Sun provides the energy for the process of photosynthesis. During the reactions of photosynthesis, solar energy transfers to chemical energy and stores in the bonds of carbohydrates, such as glucose.

Detailed explanation-3: -Plants are able to harness and use light energy in a process called photosynthesis. They absorb radiant energy from sunlight and transform it into useful chemical energy contained in molecules within their cells.

Detailed explanation-4: -The electromagnetic energy of sunlight is converted to chemical energy in the chlorophyll-containing cells of photosynthetic organisms. In eukaryotic cells these reactions occur in the organelle known as the chloroplast. In the chloroplast, chlorophyll is the pigment that absorbs the sunlight.

Detailed explanation-5: -ATP. Hint: In plants, the radiant energy from the sun will be converted into chemical energy to that of glucose (sugar). This transformation is called photosynthesis. Plants use water, carbon dioxide, and sunlight and transform these into oxygen and glucose.
