Which statement describes photosynthesis?
a. Carbon dioxide and water combine to form glucose and oxygen.
b. Carbon dioxide and glucose combine to produce energy and water.
c. Carbon dioxide, glucose, and water are released to produce energy.
d. Carbon dioxide and water are released when glucose and oxygen combine.
Your answer is A). In the presence of sunlight, plants take in the CO2 that we breathe out, and absorb water from the ground to make glucose (which the plant will use for energy when the sun isn't out), and oxygen which we breathe in again.
