movement of water Flashcards
(5 cards)
1
Q
What does water potential help predict?
A
Water potential predicts the direction of net movement of water molecules.
2
Q
From where to where does water move?
A
Water moves from a higher to a lower water potential to minimize its potential energy.
3
Q
What is the maximum value for water potential in cells?
A
The maximum value for water potential in cells is zero (0 kPa).
4
Q
Are most water potentials in cells positive or negative?
A
Most water potentials in cells are negative.
5
Q
If one cell has a water potential of -200 kPa and another has -300 kPa, which way will water move?
A
Water will move from the cell with -200 kPa to the cell with -300 kPa.
