Cells in solutions.

Question 1

hypertonic solution

Answer 1

a solution with a higher relative concentration

Question 2

isotonic solution

Answer 2

a solution with the same relative concentration

Question 3

hypotonic solution

Answer 3

a solution with a lower relative concentration

Question 4

Plant cell in hypertonic solution

Answer 4

Net movement of water out the cell Contents shrink Cell plasmolysed Protoplast pulled away completely

Question 5

Plant cell in hypotonic solution

Answer 5

Net movement of water into the cell

Cell swells and becomes turigid as of the strong cellulose cell wall.

Protoplast pushed against the cell wall.

Question 6

Red blood cell in hypertonic solution

Answer 6

Net moevement of water out of the cell

Cell shrinks and shrivals

The cell is crenated.

The cell becomes darker as the haemoglobin is more concentrated.

Question 7

Red blood cell in hypotonic solution

Answer 7

Net movement of water into the cell

cell becomes swollen and bursts

the cell is lysed

contents within the cell leaks out.
