Adaptations of Leaves
Review Describe how the structure of a leaf is adapted to make photosynthesis more efficient.
Explain What is the role of the palisade mesophyll in a leaf?
Form a Hypothesis The leaves of desert plants often have two or more layers of palisade mesophyll, rather than the single layer that is characteristic of most leaves. How might this modified structure be advantageous to a desert plant?
Review How do stomata help plants maintain homeostasis?
Predict Are stomata more likely to be open or closed on a hot day? Explain your answer.
BUILD VOCABULARY
The terms spongy and palisade are adjectives that describe two specific kinds of mesophyll. Look up these words in a dictionary to discover other contexts in which they are used. Then, explain why they are appropriate words for the types of mesophyll they describe.
