Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the compund that plants use to absorb the energy from sunlight?
A
Carbon dioxide
B
Chlorophyll
C
Nitrogen
D
H2O
Explanation: 

Detailed explanation-1: -Within the thylakoid membranes of the chloroplast is a light-absorbing pigment called chlorophyll, which is responsible for giving the plant its green color. During photosynthesis, chlorophyll absorbs energy from blue-and red-light waves, and reflects green-light waves, making the plant appear green.

Detailed explanation-2: -Most plants contain a special colored chemical or pigment called chlorophyll that is used in photosynthesis. Chlorophyll is what absorbs the sun’s energy and turns it into chemical energy.

Detailed explanation-3: -Chlorophyll a absorbs violet and orange light the most. Chlorophyll b absorbs mostly blue and yellow light. They both also absorb light of other wavelengths with less intensity.

Detailed explanation-4: -In photosynthesis, chlorophyll absorbs energy to transform carbon dioxide and water into carbohydrates and oxygen. This is the process that converts solar energy to a form that can be utilized by plants, and by the animals that eat them, to form the foundation of the food chain.
