1. Stomata Lab

2. 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.

3. 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 by Taking in water by osmosis From neighboring cells
