Osmosis

Front

What is osmosis?

Back

Osmosis is the movement of water 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

An animal cell placed in a hypertonic (salty) solution will shrink (get smaller) due to the loss of water.

Front

When does a cell most likely shrink?

Back

A cell most likely shrinks when placed in a solution containing a high salt concentration.

Front

What is equilibrium in the context of osmosis?

Back

Equilibrium is the state when the concentration of water inside and outside of a cell is equal, resulting in no net movement of water.

Front

What is active transport?

Back

Active transport is the movement of molecules against a concentration gradient, requiring energy.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of a 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 a 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 a cell, resulting in no net movement of water.

Front

What is the role of a selectively permeable membrane in osmosis?

Back

A selectively permeable membrane allows only certain molecules, like water, to pass through while blocking others.

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 molecules from an area of higher concentration to an area of lower concentration.
