Question

Olve the phrase below. "If ________ changes, then the amount of transpiration will ______ because_______."

Options:
A) Temperature; increase; it affects water loss rates
B) Wind speed; decrease; it decreases the rate of transpiration
C) Humidity; increase; it increases the rate of transpiration
D) Soil moisture; decrease; it reduces the availability of water for plants

Answer 1

The correct fill-in-the-blank statement regarding transpiration is related to humidity, which when increased, causes a decrease in transpiration due to a smaller difference in water vapor pressure between the leaf and the atmosphere.

Step-by-step explanation:

The phrase to solve is "If humidity changes, then the amount of transpiration will decrease because it reduces the differential in water vapor pressure between the leaf and the atmosphere." This is explained by understanding that transpiration is the process by which water vapor is lost from plant leaves to the external environment. Humidity affects this process because when the air is more humid, there is less of a difference in water vapor pressure between the inside of the leaf and the atmosphere outside, leading to a slower rate of water vapor loss.
