Biology (Day 16; Osmosis and Tonicity)

Question 1

Osmosis

Answer 1

the net movement of water across semi-permeable membrane from an area of low solute concentration to high solute concentration

Question 2

Tonicity

Answer 2

the ability of an extracellular solution to make water move into or out of a cell by osmosis

Question 3

Hypertonic solution

Answer 3

higher solute in solution than in cell; water moves out of the cell; cell shrinks and shrivels up

Question 4

Hypotonic solution

Answer 4

higher solute in cell than in solution; water moves into the cell; cell swells

Question 5

Isotonic solution

Answer 5

equal solute in cell and solution; water moves into and out of the cell at the same rate; cell doesn’t change

Question 6

Osmosis is what type of transport?

Answer 6

passive transport
