Meaning
A guard cell is a specialised cell in a plant leaf which contains can change shape to allow or stop gases from getting into the leaf.
Adaptations of the Guard Cell
- Guard cells can change shape to open and close a hole called a stoma.
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.
