Osmosis and Hypertonic Solutions

The video explains osmosis, a passive transport process where water moves across a membrane from high to low concentration. It highlights how water moves towards areas with higher solute concentration, making them hypertonic. The video uses diagrams to illustrate how cells swell or shrivel based on the surrounding solution's tonicity.

What is the primary characteristic of passive transport in osmosis?

• Movement of solutes from low to high concentration

• Movement of solutes from high to low concentration

• Movement of water from high to low concentration

• Movement of water from low to high concentration

In osmosis, water moves towards an area with:

• Higher water concentration

• Equal solute and water concentration

• Lower solute concentration

• Higher solute concentration

What does it mean if a solution is hypertonic?

• It has a higher water concentration

• It has an equal solute concentration

• It has a higher solute concentration

• It has a lower solute concentration

In diagram 1, if the cell is hypertonic, what will happen to the cell?

• It will shrink

• It will swell

• It will remain the same

• It will burst

In diagram 2, if the solution is hypertonic, what will happen to the cell?

• It will swell

• It will burst

• It will shrink

• It will remain the same
