Water potential Flashcards
(6 cards)
1
Q
What does water potential mean?
A
It’s the concentration of water molecules in an area. High water potential = more water
Low water potential = less water
2
Q
What kind of water has a high water potential?
A
A dilute solution (lots of water)
3
Q
What kind of water has a low water potential?
A
A concentrated solution (less water)
4
Q
In what direction does water move during osmosis?
A
From high water potential, to low water potential
5
Q
Does osmosis require energy?
A
No as it is passive. It happens down the concentration gradient
6
Q
Why is osmosis important to organisms?
A
It controls how they take in or lose water, which is vital for survival
