A student moves a plant from dim light into bright light. The temperature and air movement remain constant, and the plant has enough water.
Which linked changes are most likely?
more stomata close and the rate of water uptake increases
more stomata open and the rate of water uptake increases
more stomata open and the rate of water uptake decreases
more stomata close and the rate of water uptake decreases
