Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What are the raw materials of photosynthesis?
A
oxygen and carbon dioxide
B
oxygen and glucose
C
carbon dioxide and water
D
water and glucose
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf. Oxygen, a by-product of photosynthesis, and water vapor exit the leaf. In most land plants, water enters the roots and is transported up to the leaves through specialized cells known as xylem (pronounced zigh-lem).

Detailed explanation-3: -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-4: -Carbon dioxide and water are the main raw materials for the process of photosynthesis. Besides, light energy and chlorophyll are also raw materials for photosynthesis. Sunlight is the energy source, which is essential for photosynthesis to take place.

Detailed explanation-5: -Thank you, photosynthesis! A plant cell uses carbon dioxide (CO2) and water (H2O) as inputs-the former so that it can convert carbon into a solid form and the latter as a source of electrons-and creates glucose (C6H12O6) and oxygen (O2) as outputs. Oxygen is sort of a waste product in this process, but not really.
