Cold temperatures cause reactions to proceed so quickly that metabolism becomes unbalanced.b.
At high temperatures, Rubisco accepts too much carbon dioxide, resulting in a wasteful process called photorespiration. When temperatures are too high, membranes are affected. Plants must use energy to actively transport nutrients like phosphorus into their roots.b. Low concentrations of nutrients in the soil may result in greater root growth in plants.c. The pH of the soil may influence the plant s ability to obtain nutrients.d.
