Stomata Lab

Transpiration

• The evaporation of water through plant leaves• Has the same effect on plant leaves as perspiration does on human

skin. • As water evaporates it takes away heat.

Guard Cells

• Allows the leaf to maintain a sufficient water balance, obtain carbon dioxide and release oxygen• Guard cells open and close their stomata – water evaporates through

there and through which carbon dioxide and oxygen gases pass through.• Guard form stomata byTaking in water by osmosisFrom neighboring cells
