A plant takes up 4.2 cm3 of water and loses 5.0 cm3 of water in one hour. At the start of the hour, its cells are turgid.
If these rates continue, which change is most likely?
Cells gain turgor because water loss exceeds water uptake.
Cells lose turgor because water loss exceeds water uptake.
Cells lose turgor because water uptake exceeds water loss.
Cells gain turgor because water uptake exceeds water loss.
