- Gaseous Exchange in Plants
- Stomata
- Stomata are small pores found on the lower surface of the leaf.
- The Stomata allow exchange of gases between the atmosphere and the internal tissues of the leaf.
- Water also evaporates from a plant through the Stomata which links to Transpiration.
- Plants wilt if they lose too much water.
- Since light hits the upper surface of the leaf, confining Stomata to the lower surface reduces water loss.
- Stomata closes at night to help reduce the pointles loss of water.
- Guard cells are unusual in having chloroplasts and unevenly thickened walls, with the inner wall being thick and the outer wall being thin.
