About Guard Cells
- Guard cells are shaped with a gap between them called a stoma.
- There are more guard cells found on the bottom of the leaf.
- Guard cells fill with water to become turgid. This makes the stoma larger. When the leaf gets dehydrated the guard cells become flaccid. This makes the stoma smaller.
