Why do land plants have stomates (sometimes called stomata)? a. To allow plants to take in carbon dioxide from the atmosphere. b. All of the choices are true; none are false. c. To control water loss while allowing for the uptake of some raw materials of photosynthesis. d. They allow the plant to have some control over transpiration rates.

Allowing for rapid movement of ions into the cell through plasmodesmata linking guard cells to neighboring cells. e. Recognizing environmental cues such as high CO2 within the leaf.
Which of the following options best explains how less chlorophyll would affect the proces of photosynthesis in plants? 6. A. It would increase the rate of photosynthesis because of the increased production of food. B. It would limit the amount water plants are able to take in, resulting in a slower rate of photosynthesis. C. It would increase the production of oxygen because the plant would need to work hard to feed themselves. С. D. It would limit the amount of light absorbed by the plant and decrease the amount of food the plant is able to produce for itself.
Cottonwood trees are commonly found along river banks and irrigation ditches. They have broad flat leaves and can transpire 200 gallons of water per day. Many succulent plants live in hot, arid environments and have thick leaves with a wax-like substance covering their leaves. They generally open their stomata for gas exchange at night. Using your understanding of transpiration, find the adaptations that allow these plants to survive in their respective environments.
