Question

Plants lose __ % water to transpiration resulting in 10% increase in atmospheric water vapor which increases relative humidity and chance of precipitation.

A: 90
B: 10
C: 100
D: 45​

Answer 1

Answer: A

Explanation: Transpiration is the loss of water from the plant through evaporation at the leaf surface. It is the main driver of water movement in the xylem. Transpiration is caused by the evaporation of water at the leaf–atmosphere interface. Up to 90 percent of the water taken up by roots may be lost through transpiration as only a small amount of that water is used for growth and metabolism.
