Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Leaves use the energy from the sun to change carbon dioxide and water into what?
A
chlorophyll
B
oxygen
C
carbon dioxide
D
sugar
Explanation: 

Detailed explanation-1: -This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

Detailed explanation-2: -Plants use a process called photosynthesis to make food. 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.

Detailed explanation-3: -The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas. After the sugar is produced, it is then broken down by the mitochondria into energy that can be used for growth and repair.

Detailed explanation-4: -In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process. Carbon dioxide and water are products of this reaction. At the level of individual steps, photosynthesis isn’t just cellular respiration run in reverse.

Detailed explanation-5: -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.
