Mark "A" for active, "P" for passive, and "B" for statements that apply to both types of transport.

1.) Osmosis is an example of this

2.) Moves substances from low to high

3.) Requires the use of ATP/energy

4.) Moves with the concentration gradient

5.) Creates equilibrium across the cell membrane

6.) Moves particles across the cell membrane

hyp tonic

solutions cause cells to swell

*Solution has a higher water concentration than the cell, causing water to rush into the cell until

equilibrium is reached

hyp tonic

solutions cause cells to shrink

*solution has a lower water concentration than the cell, causing water to leave the cell until equilibrium is

reached

isotonic solutions

contain equal concentrations of

water inside and outside the cell
