Which phrase best describes the light that plants transform into chemical energy by the process of photosynthesis?
a. infrared light
b. ultraviolet light
c. red and blue light
d. green light

C. red and blue light

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 chlorophyll.  The light absorbed by chlorophyll is blue and red light and reflect the green light.

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.

it means there are 3 atoms of oxygen
