Water moves from a plant to the atmosphere through the leaves.
How is the volume of water lost from the leaves controlled?
Describe the transport of water through a plant from the roots to the atmosphere.
A student investigated the volume of water lost from two plants of different species, Plant P and Plant Q, over a 3.5-hour period. Both plants were kept together in the same environmental conditions. At 3.0 hours, both plants were moved to a different environment.
Figure 1 shows the student's results.
Suggest one reason for the difference in the rate of water loss from the two plants in the first 3.0 hours.
Calculate the rate of water loss per hour in Plant Q from 3.0 hours to 3.5 hours. Give your answer to 2 significant figures.
Suggest two reasons why the rate of water loss in both plants changed after 3.0 hours.
