Question

question 1-1
a scientist measured the amount of oxygen released by two trees of the same species. tree b released significantly more oxygen than tree a. based on the process of photosynthesis, what occurred to allow tree b to release more oxygen?

• it received more water
• it received more sunlight
• it received more glucose
• it received more carbon dioxide

Explanation:

Oxygen released during photosynthesis comes from the splitting of water molecules. The rate of this reaction (and thus oxygen output) increases with more available water, as water is the direct source of the oxygen released. Sunlight, carbon dioxide are also reactants, but oxygen's origin is water; glucose is a product, not a reactant that drives oxygen release.

Answer:

A. It received more water
