Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following describes the primary energy conversion that occurs when plants produce sugar?
A
Chemical energy is converted to light energy.
B
Chemical energy is converted to mechanical energy.
C
Light energy is converted to mechanical energy.
D
Light energy is converted to chemical energy.
Explanation: 

Detailed explanation-1: -Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.

Detailed explanation-2: -Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Detailed explanation-3: -Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules (e.g., sugars).

Detailed explanation-4: -solar energy is converted into chemical energy.

Detailed explanation-5: -Glossary. Photosynthesis: ↑ The process green plants use to produce energy, in the form of sugar, from sunlight, water, and carbon dioxide. Chloroplast: ↑ Small structures inside leaves that conduct photosynthesis. Chlorophyll: ↑ Pigments inside chloroplasts that absorb the light energy from sunlight.
