When there is not enough carbon dioxide in a plant, a process called photorespiration may occur. This process uses the excess ox
sergiy2304 [10]

A prolonged period of photorespiration would affect a plant, giving a significant evolutionary advantage to plant species in dry climates.

<h3>What is the difference between photorespiration and respiration?</h3>

One of the basic differences between photorespiration and respiration concerns the effect of O2 on the two processes. Respiration saturates when O2 reaches approximately 2%, while photorespiration does not reach saturation in a pure O2 atmosphere.

<h3>Under what conditions does photorespiration occur?</h3>

Photorespiration is an expensive metabolic pathway that occurs when the Calvin Cycle enzyme rubisco acts on oxygen instead of carbon dioxide.

With this information, we can conclude that A prolonged period of photorespiration would affect a plant, giving a significant evolutionary advantage to plant species in dry climates.
