An experiment proving transpiration in leaves Aim To see how different environmental conditions affect transpiration of a leaf and which side of the leaf transpires the most. Background Information Plants put down roots into the soil to draw water and nutrients up into the stems and leaves. Some of this water is returned to the air by transpiration (when combined with evaporation‚ the total process is known as evapotranspiration). Transpiration rates vary widely depending on weather conditions

Transpiration Abstract This lab demonstrates how different environments effect the rate of transpiration in plants. A potometer is set up and placed in four different environments: one simply at room temperature (the control)‚ one with a fan pointing toward it creating a gentle breeze‚ on with a floodlight on it and a beaker felled with water as a heat sink‚ and one where the leaves are misted then covered with a transparent plastic bag. It is imperative that the tubing doesn ’t have any bubbles
