1
Q

osmosis

A

osmosis is the movement of water molecules across a partially permeable membrane from a region of higher water concentration to a region of lower water concentration

2
Q

partially permeable membrane

A

partially permeable membrane allow some small molecules to pass through but not all molecules

3
Q

plant cell in water

A

water will move into the cell by osmosis and will expand

-the cell wall prevents the plant cell from bursting and instead become turgid (swollen)

4
Q

plant cell in a concentrated solution

A

water moves out of the cell via osmosis . this causes the cell to be flaccid (to shrink)

5
Q

animal cell in water

A

water will move into the cell by osmosis, causing it to expand and even burst

6
Q

animal cell in a concentrated solution

A

water moves out of the cell via osmosis, causing it to shrink
