Define Osmosis
Net movement of water particles from an area of high concentration to low concentration across a partially permeable membrane
In a hypertonic solution, which direction will water move, and what will happen to the mass of the cell?
Water will move out of the cell causing the mass of the cell to decrease.
A cell is sitting in a hypotonic solution. Which direction will water move and how will the mass in the cell change?
Water will move into the cell causing the mass to increase
Why do plant cells store glucose as amylose/amylopectin and animal cells store it as glycogen?
Have no osmotic effect
How does the ratio of amylopectin to glucose stored in a cell impact the movement of water via osmosis?
A higher ratio of amylopectin reduces the osmotic concentration inside the cell so there is less water movement.
