During the process of transpiration, water is pulled up from the roots and into the leaves of the plant for use during photosynthesis. If the plant has excess water in the leaves, transpiration
releases that water into the air.

Based on the description of transpiration, what internal and external conditions would most
likely cause this process to occur?
A. There is a lack of water in the plant, and it’s daytime
B. There is a lack of water in the plant, and it is nighttime
C. There is plenty of water in the plant, and it is daytime
D. There is plenty of water in the plant, and it is nighttime
