In a comparison of the water potential and turgor pressure of leaf cells before and after wilting, which of the following would you expect to find?
Select one:
a. Water potential: wilted = not wilted; Turgor Pressure: wilted < not wilted
b. Water potential: wilted > not wilted; Turgor Pressure: wilted < not wilted
c. Water potential: wilted < not wilted; Turgor Pressure: wilted > not wilted
d. Water potential: wilted < not wilted; Turgor Pressure: wilted < not wilted
e. Water potential: wilted > not wilted; Turgor Pressure: wilted > not wilted
We know that short-day plants do not really need short days, but actually long nights. Describe the type of treatment that proves this. Is some kind of light given during the night or some period of darkness given during the day?
