LAB 9 NOTE: These labs are known for high failure rates. Therefore, if I show an example using data, a graph, etc… yours may be totally different depending upon mine and yours success with the lab. So don’t freak if your data is completely different from mine. And therefore the analysis of results sometimes may need to be answered differently since you base your analysis off your data and not mine. DISCLAMIER: DO NOT CHEAT! Introduction Transpiration is the process through which water is lost from a plant by evaporation . Water is taken into a plant through roots and root hairs by osmosis , and it exits the plant through ting openings on the underside of leaves known as stomata . Oxygen and carbon dioxide are exchanged through the stomata. Transpiration is also the major mechanism that powers the movement of water throughout a plant. This transportation of water through the plant is due to water potential . Water potential is the potential energy created by the water molecules within the plant stem. Water always flows from areas of high water potential to areas of low water potential. Gravity, pressure, and solute concentration are all factors determining water potential in a plant. There are three main kinds of cells in plants. the most abundant is parenchym a cells. These cells are mainly unspecialized and make up the mesophyll layer in leaves. Most parenchyma cells store food such as starch to be used later in the plant. Sclerenchyma cells are lignified and dead at maturity. These cells make up fibers and have thick
