1
Q
Osmosis definition
A
the movement of water molecules from a region of higher concentration to a region of lower concentration. It happens across cell membranes
2
Q
Solute definition
A
the thing which is dissolved in water
3
Q
Hypotonic solution definition
A
hypotonic solutions have more dissolved stuff inside the cell thant inside the solution. Water rushes into the cell, causing it to swell
4
Q
Isotonic solution definition
A
If the concentration of dissolved stuff inside the cell matches that outside the cell, it is an isotonic solution. Water moves in and out at a steady rate - no changes to the cell
5
Q
Hypertonic solution definition
A
Hypertonic oslutions have more dissolved stuff in the solution than inside the cell. Water moves out of the cell, shrinking it
