B1: Osmosis

Question 1

osmosis

Answer 1

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

Question 2

partially permeable membrane

Answer 2

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

Question 3

plant cell in water

Answer 3

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)

Question 4

plant cell in a concentrated solution

Answer 4

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

Question 5

animal cell in water

Answer 5

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

Question 6

animal cell in a concentrated solution

Answer 6

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