WebUnder normal circumstances, the rate of water uptake gives a measure of the rate of transpiration. A simple potometer is a piece of capillary tubing to which a plant has been connected. The water uptake is measured by recording the time taken for a bubble in the tube to move a set distance. Web(c) A student used the apparatus shown in Fig. 4.1 to investigate how transpiration rates vary during the day. The student placed the potometer on a window ledge in the laboratory. He estimated the rate of transpiration four times during the day. The results are shown in Table 4.1. Table 4.1 WebThe rate of transpiration is influenced by a variety of factors, including the humidity and temperature of the air, the amount of light available to the plant, and the size and structure of the plant's leaves.
