: [[Photosynthesis]] needs water, so '''guard cells''' are there to make sure the [[leaf|leaves]] don't use up too much [[water]] and die of [[Dehydrate|dehydration]].: '''Guard cells''' fill with water to become [[turgid]], making the [[stoma|stomata]] larger. This makes allows [[Carbon Dioxide|carbon dioxide]] into the [[stomaleaf]] for [[photosynthesis]] larger. : When the [[leaf]] gets dehydrated the '''guard cells''' become [[flaccid]]. This makes making the [[stoma|stomata]] smaller.This stops [[Carbon Dioxide|carbon dioxide]] from getting into the [[leaf]] and prevents [[photosynthesis]]
