PROPERTIES OF WATER

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The raw materials or reactants of photosynthesis are
A
sugar and water.
B
sugar and oxygen.
C
carbon dioxide and water.
D
carbon dioxide and oxygen.
Explanation: 

Detailed explanation-1: -Raw materials for photosynthesis are carbon dioxide, water, and sunlight. Carbon dioxide is produced through the exchange of gases. This function is performed by stomata.

Detailed explanation-2: -The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf, and the products of photosynthesis, sugar and oxygen, leave the leaf. Water enters the root and is transported up to the leaves through specialized plant cells known as xylem vessels.

Detailed explanation-3: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. 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.

Detailed explanation-4: -During photosynthesis, light energy converts carbon dioxide and water (the reactants) into glucose and oxygen (the products).

Detailed explanation-5: -The conversion of sunlight into usable chemical substances is attained by chlorophyll. The raw materials needed for the process of photosynthesis are CO2 and H2O. 6 molecules of water and 6 molecules of carbon dioxide with the help of sunlight produce glucose and 6 molecules of oxygen.
