Answer: surround the opening of the stomata and control the flow of air throught
the stomata of the leaf. when teh guard cells/leaf are dehydrated, they
will close the stomata and reduce the flow of air through the leaf,
preventing further dehydration of the leaf cells. when there exists
adequate moisture within the guard cells/leaf, the guard cells will open up
the stomata and allow air to freely flow through the leaf
