PHOTOSYNTHESIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What are the REACTANTS (ingredients) for photosynthesis?
A
glucose and oxygen
B
water and carbon dioxide
C
water and glucose
D
carbon dioxide and oxygen
Explanation: 

Detailed explanation-1: -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-2: -During photosynthesis, light energy converts carbon dioxide and water (the reactants) into glucose and oxygen (the products).

Detailed explanation-3: -Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.

Detailed explanation-4: -Photosynthesis converts carbon dioxide and water into oxygen and glucose.

Detailed explanation-5: -The photosynthesis chemical equation states that the reactants (carbon dioxide, water and sunlight), yield two products, glucose and oxygen gas. The single chemical equation represents the overall process of photosynthesis.
