Lower leaf counts reduce water loss through stomates, stems, and other plant parts. Some buds, blossoms, and growing fruit may fall off. The plant response to heat stress may also involve decreasing its metabolic rate.

WebThe next day, measure the beakers. (It may take more than one day) Explain what evaporation is and then introduce the water cycle. You can demonstrate that evaporation is when water changes from a liquid to a gas with the beakers of hot water. You can also hold the mirror over the hot water beaker to show steam fogging it. Weba scale to measure the distance travelled by a bubble in the capillary tube; The faster the bubble moves, the greater the rate of water uptake - and so the greater the rate of transpiration.
