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: -The reactants for photosynthesis are light energy, water, carbon dioxide and chlorophyll, while the products are glucose (sugar), oxygen and water. The reactant water molecule is taken up from the soil by the roots for splitting and producing oxygen.

Detailed explanation-3: -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.

Detailed explanation-4: -Plants make sugar by using energy from sunlight to transform carbon dioxide (CO2), a gas absorbed from the air, and water (H20) taken from the ground by roots into glucose (C6H12O6) and oxygen (O2). This process is called photosynthesis and occurs in the chloroplast of the plant cell.

Detailed explanation-5: -Answer and Explanation: The reactants of photosynthesis are water, H2O H 2 O, and carbon dioxide, CO2 C O 2, and the products are glucose, C6H12O6 C 6 H 1 2 O 6, and oxygen gas, O2 .
