Question

Quizplus · Accepted Answer

If the guard cells and surrounding epidermal cells in a plant are deficient in potassium ions, photosynthesis (A) would decrease because stomata would be closed (E), reducing the amount of carbon dioxide available for photosynthesis. Roots (B) would take up less water because stomata would be closed, reducing transpiration and therefore the pull of water from the roots. Phloem transport rates (C) would decrease due to a lack of water and nutrients being transported to the rest of the plant. However, leaf temperatures (D) would not decrease; in fact, they may increase as stomata close and less heat is dissipated through transpiration.
