Osmosis

Question 1

Define isotonic solution

Answer 1

When the concentration of solutes outside of a cell is similar to that inside the cell

Question 2

Define hypotonic solution

Answer 2

When the concentration of solutes outside of the cell is lower than in the cytoplasm

Question 3

Define hypertonic solution

Answer 3

When the concentration of solution is higher than inside the cell

Question 4

What is cell membrane permeable to

Answer 4

Water

Question 5

What is cell membrane impermeable to

Answer 5

Sucrose

Question 6

What happens when fluid is hypotonic to the cytoplasm of the plant cell

Answer 6

Water will enter the cell by osmosis

Question 7

What happens as the cytoplasm swells and presses against the cell wall

Answer 7

The cell wall generates hydrostatic pressure

Question 8

What cancels out the tendency of water molecules to move in

Answer 8

The inward pressure of the cell wall on the cytoplasm increases

Question 9

What is the inward pressure known as

Answer 9

Pressure potential

Question 10

What is turgor

Answer 10

The state of a plant cell when the solute potential causing water to be moved into the cell by osmosis is balcned by the force of the cell wall pressing on the protoplasm

Question 11

What happens when plants cell are put into a solution which is slightly hypertonic

Answer 11

Water moves out of the cell by osmosis and turgor is lost

Question 12

Define water potential

Answer 12

The tendency for water to move out of a solution by osmosis
