Question

what do plants produce as a by-product of photosynthesis?
(1 point)
○ water and carbonic acid
○ carbon dioxide and water
○ oxygen and glucose
○ hydrogen and carbon dioxide

Explanation:

The process of photosynthesis in plants uses carbon dioxide and water (with light energy) to produce glucose (for energy/starch) and oxygen is released as a by - product. The other options do not match the products of photosynthesis: water and carbonic acid are not photosynthesis products; carbon dioxide and water are reactants; hydrogen and carbon dioxide are not photosynthesis products.

Answer:

oxygen and glucose
