Chapter 38, Problem 5A
You decide to plant a garden with a beautiful black walnut tree at one end and a majestic white oak at the other end. You are quite disappointed, however, when none of the seeds you plant around the walnut tree grow. What might explain this observation?
a. The walnut tree filters out too much light, so the seeds fail to germinate.
b. The roots of the walnut tree deplete all of the nutrients from the soil, so the new seedlings starve.
c. The walnut tree produces chemical toxins that prevent seed germination.

c. The walnut tree produces chemical toxins that prevent seed germination.
Plant fertilizer consists of numerous different solutes (usually salts). A small dose of
fertilizer can enhance plant growth, but overfertilization can kill the plant. Why might
overfertilization have this effect?
Guard cells surround stomata on the surface of leaves. A new herbicide targets the function of guard cells
and prevents them from becoming flaccid and closing the stomata. What effect would the herbicide have
on plants?
a.Plants would dry out because guard cells protect the epidermis against desiccation.
b.Plants would be eaten because guard cells protect leaves against herbivores.
c. Plants would dry out because stomata would not be able to close.
d.lt would regulate the intake of minerals in the plants.
