Choose all the correct statements for the graph above:  A.in a mutant plant that makes TWICE the normal number of stomata on the leaf, we would expect the line to shift down (i.e. water potential would become more negative). B. During the period starting with time B and ending with time D, the water potential in the leaf is increasing. C.Transpiration rates are the highest around time B. D.At time A we expect to see the greatest volume of water moving up the xylem to this leaf.

The primary growth of a plant is due to the action of the ________. a. lateral meristem b. vascular cambium c. apical meristem d. cork cambium

All other factors being equal, tiny hairs near the stomata will _______ transpiration. All other factors being equal, an increase in wind speed will _______ transpiration. Select one: a. decrease, decrease b. increase, decrease c. increase, increase d. decrease, increase

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.
