CAM and C4 plants are plants that are found naturally in hot, dry climates. In these climates, they have to have their stomata ______
for long periods of time to conserve ______ which increases their risk of photorespiration. CAM and C4 plants have evolved a separate chemical
reaction to minimize photorespiration.

In the fellowing chart, decide whether each description listed in the left-hand column applies to CAM plants, C4 plants, or both. For each row, check all
that apply.
