Homework
Make a KWL chart for this unit.
How is a plant different from an animal?
Compare a cactus to a rose to an apple tree to a pine tree. Why do you think plants have such different structures?
What proof do we have that people need plants as much as we need them? (Think about recycling!)

Homework Cont’d
In some land plants, guard cells are found only on the lower surfaces of the leaves. In some water plants, guard cells are found only on the upper surfaces of the leaves. Explain how guard cells in both land and water plants help maintain homeostasis. In your answer be sure to:
• identify one function regulated by the guard cells in leaves
• explain how guard cells carry out this function
• give one possible evolutionary advantage of the position of the guard cells on the leaves of land plants
