When compared to the amount of oxygen produced in the process of photosynthesis, the amount of oxygen used in plant respiration is:
|
|
about the same
|
|
|
less
|
|
|
more
|
|
|
much more
|
Explanation:
Detailed explanation-1: -Oxygen production and the rate of photosynthesis have a direct relationship. This means as the rate of photosynthesis increases, more oxygen will be produced also. This is because oxygen is created as a waste product from the light reactions in photosynthesis.
Detailed explanation-2: -Oxygen (O2) is evolved during photosynthetic electron transport when water is split by the oxygen-evolving complex to provide protons and electrons to the chloroplastic electron chain, thereby generating ATP and NADPH-the energy source and reducing power for plant metabolism.
