1.1 - Osmosis Flashcards
1
Q
What is osmosis?
A
- The movement of water
- The diffusion of water across a partially (or semi-permeable) membrane
2
Q
Describe the movement of water molecules across a semi-permeable membrane
A
Just like diffusion, the movement of water molecules is random and requires so energy from the cell
3
Q
How does water move in and out of cells?
A
Osmosis through the cell membrane
4
Q
What type of membrane is cell membrane?
A
Semi-permeable/partially permeable
5
Q
What does the net movement of water move from and to?
A
From a dilute solution to a more concentrated solution
6
Q
What is a dilute solution?
A
A region of high water concentration
7
Q
What is a concentrated solution?
A
A region of low water concentration
