18. How does the air get into the leaf?
Through tiny pores on the bottom of a leaf called stomata

19. What does “evaporation” mean?
Part of the water cycle --> when water moves from a liquid to a gas form

20. Plants help with the evaporation process when water evaporates or turns from liquid to gas when it is released through their leaves. What is this process called?
Transpiration: when water evaporates from a plant’s leaves
