Osmosis - As Level

Water potential is measured in units of kPa (kilopascals).

• True

• False

Adding solute to a solution increases its water potential.

• False

• True

Pure water has the highest water potential, which is defined as 0 kPa

• False

• True

During osmosis, water moves from areas of lower water potential to areas of higher water potential.

• False

• True

Osmosis requires energy from ATP to occur.

• True

• False

If a solution has a water potential of -800 kPa, it has a higher solute concentration than a solution with a water potential of -300 kPa.

• True

• False

Osmosis only occurs when a selectively permeable membrane is present.

• False

• True

Water potential is influenced by both solute concentration and pressure.

• False

• True

When a cell with a water potential of -500 kPa is placed in a solution with a water potential of -200 kPa, water will move into the cell.

• False

• True

A solution with a high solute concentration has a high water potential.

• False

• True
