What must a plant need to produce 4 molecules of sugar?
Amiraneli [1.4K]

Answer:

24 molecules of H20

Explanation:

Photosynthesis:

It is the process in which in the presence of sun light and chlorophyll by using carbon dioxide and water plants produce the oxygen and glucose.

Carbon dioxide + water + energy →   glucose + oxygen

water is supplied through the roots, carbon dioxide collected through stomata and sun light is capture  by chloroplast.

Chemical equation:

6H₂O + 6CO₂ + energy  →   C₆H₁₂O₆ + 6O₂

it is known from balanced chemical equation that 6 moles of carbon dioxide react with the six moles of water and created one mole of glucose and six mole of oxygen.

consider 1 mole contain 1 molecule.

So in order to produced 4 molecules of sugar number of molecules of water carbon dioxide needed are,

6 × 4 = 24 molecules

24 molecules of water and 24 molecules of carbon dioxide needed.
