Water moves from a plant to the atmosphere through the leaves.
How is the volume of water vapour leaving the leaves regulated by the plant?
Describe how water is transported from the soil, through a plant, and into the atmosphere.
A student investigated the volume of water lost from two different plant species, Species X and Species Y, over a 2.5-hour period. Both plants were initially kept together under the same environmental conditions. At 2.0 hours, both plants were moved to a different environment.
Figure 1 shows the student's results.
Suggest one anatomical reason for the difference in the rate of water loss between Species X and Species Y before they were moved to the new environment.
Calculate the rate of water loss per hour for Species Y between 2.0 hours and 2.5 hours. Give your answer to 2 significant figures.
Suggest two environmental changes that could explain the change in the rate of water loss in both plants after 2.0 hours.
