Resource summary

Question 1

Question
Cell membranes are:
Answer
  • Fully permeable
  • Selectively permeable
  • Impermeable
  • Sometimes permeable and sometimes impermeable

Question 2

Question
Osmosis is:
Answer
  • Diffusion of gases from high concentration to low concentration
  • Diffusion of molecules from a region of low concentration to high concentration across a semi-permeable membrane
  • Diffusion of water molecules from a region of high water concentration to low water concentration across a semi-permeable membrane
  • Diffusion of molecules from a region of high concentration to low concentration across a semi-permeable membrane

Question 3

Question
What happens to a plant cell when it loses water?
Answer
  • It becomes plasmolysed
  • It becomes turgid
  • It undergoes crenation
  • It undergoes mitosis

Question 4

Question
What would happen to a human blood cell if it was placed in a solution that was less concentrated than itself?
Answer
  • It would become plasmolysed
  • It would become turgid
  • It would undergoes crenation
  • It would burst

Question 5

Question
What would happen to a human blood cell if it was placed in a solution that was more concentrated than itself?
Answer
  • It would become plasmolysed
  • It would become turgid
  • It would undergo crenation
  • It would burst

Question 6

Question
Using your knowledge of osmosis, choose which option best describes what would happen to you if you drank sea water.
Answer
  • You would become fully hydrated and your thirst would be quenched
  • Nothing would happen
  • You would become even more dehydrated as water would move from your blood into your stomach
  • After a short time it would increase urine formation by the kidneys

Question 7

Question
Turgor is:
Answer
  • Pressure of the cell wall on the cell membrane
  • Pressure of the cell contents on the cell wall
  • Movement of water into a cell
  • Movement of water out of a cell

Question 8

Question
Plasmolysis is:
Answer
  • Pressure of the cell wall against the cell membrane
  • Pressure of the cell contents on the cell wall
  • When the cell membrane has lost water and peels away from the cell wall
  • When water moves into the plant cell

Question 9

Question
Which one of the following is unsuitable for use as a semi-permeable membrane to demonstrate osmosis?
Answer
  • Dialysis tubing
  • Visking tubing
  • Cellophane
  • Plastic bag

Question 10

Question
Which of the following is not an application of osmosis:
Answer
  • Salting food
  • Cold smoking food
  • Adding sugar to food
  • Dehydration of food
