Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following describes the major energy transformation taking place in photosynthesis
A
Radiant energy is being converted into chemical energy
B
Sound energy is being converted into potential energy
C
Chemical energy is being converted into electrical energy
D
Mechanical energy is being converted into kinetic energy
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -The main energy transformation that occurs in photosynthesis in green leaves is Light energy to chemical energy.

Detailed explanation-3: -The Two Parts of Photosynthesis Photosynthesis takes place in two stages: the light-dependent reactions and the Calvin cycle. In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water.

Detailed explanation-4: -So, the correct answer is ‘Kinetic energy to chemical energy to potential energy’.

Detailed explanation-5: -Answer: Solar energy is converted into chemical energy during photosynthesis.
