Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What are water and carbon dioxide converted into by the end of photosynthesis?
A
air and sunlight
B
water and air
C
sugar and water
D
sugar and oxygen
Explanation: 

Detailed explanation-1: -Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. 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: -In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct.

Detailed explanation-3: -During photosynthesis, light energy converts carbon dioxide and water (the reactants) into glucose and oxygen (the products).

Detailed explanation-4: -Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by-products and ATP is energy that is transformed from the process.

Detailed explanation-5: -The first product of photosynthesis is sugar and it is converted into starch in all plants. The initial process of photosynthesis is the decomposition of water into oxygen, which is released and hydrogen. Direct light is required for this process.
