Osmosis

Front

What is osmosis?

Back

Osmosis is the movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

What happens to an animal cell in a hypertonic solution?

Back

The animal cell will shrink due to the loss of water.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing water to move out of the cell.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing water to move into the cell.

Front

What is isotonic solution?

Back

An isotonic solution has the same concentration of solutes as the inside of the cell, resulting in no net movement of water.

Front

What is selective permeability?

Back

Selective permeability is the ability of a cell membrane to allow some substances to pass through while blocking others.

Front

What effect does salt water have on carrots?

Back

Placing carrots in salt water causes them to become rubbery due to water loss.

Front

What direction do water molecules move in osmosis when there is a higher concentration of water inside the cell?

Back

Water molecules move out of the cell, causing the cell to shrink.

Front

What is the role of the plasma membrane in osmosis?

Back

The plasma membrane regulates the movement of water and solutes in and out of the cell.

Front

What is the difference between osmosis and diffusion?

Back

Osmosis specifically refers to the movement of water, while diffusion refers to the movement of any type of molecules from high to low concentration.
