Osmosis Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what’s on both sides.
  • Make sure you understand the information on each card. If something’s unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It’s useful to remember specific examples to understand these concepts better.

What is osmosis?

Osmosis is the movement of water molecules from a region of high concentration to a region of low concentration across a partially permeable membrane.

What happens to water molecules in osmosis when there is a high concentration on one side of the membrane and a low concentration on the other?

Water molecules move from the side with a high concentration (dilute solution) to the side with a low concentration (concentrated solution).

What is the effect of osmosis on plant cells in a hypotonic solution?

Water moves into the cell, causing it to swell and become turgid.

What is plasmolysis in plant cells?

Plasmolysis is the process where plant cells lose water and shrink in a hypertonic solution.

How does osmosis affect animal cells in a hypertonic solution?

Water moves out of the cell, causing it to shrink and potentially die.

What can happen to a red blood cell in a hypotonic solution?

Water moves into the cell, causing it to expand and possibly burst.
