Osmosis

Question 1

What’s osmosis?

Answer 1

Net movement of water from an area of high concentration of water molecules, to an area of lower concentration of water molecules, through a partially permeable membrane = until equilibrium is reached.

Question 2

What’s hypertonic water?

Answer 2

A solution that has a higher concentration of solutes (salt or sugar) than the cytoplasm of a cell.

Question 3

Which way does the water move in hypertonic water?

Answer 3

Water moves out of the cell into the surrounding solution to balance the solute concentrations.

Question 4

Effects on a cell due to hypertonic water:

Answer 4

Shrink due to water loss
Process=Crenation

Question 5

Summary of hypertonic water:

Answer 5

Water moves out of the cell = leading to dehydration & shrinkage of the cell.

Question 6

What’s hypotonic water?

Answer 6

Solution that has a lower concentration of solutes (salt or sugar) than thecytoplasm of a cell.

Question 7

Which way does the water move in a hypotonic solution?

Answer 7

Water moves into the cell from the surrounding solution to balance the solute concentrations.

Question 8

Effects on the cell due to hypotonic water:

Answer 8

Cells swell and may burst due to excessive water intake.
