Front

What happens to a cell in a hypotonic solution?

Back

A cell will swell and possibly burst.

Front

What type of solution has a higher concentration of solutes outside the cell than inside?

Back

Hypertonic solution.

Front

Define osmosis.

Back

The movement of water across a semipermeable membrane from low to high solute concentration.

Front

In a hypotonic solution, which way will water move?

Back

Water will move into the cell.

Front

What is tonicity in relation to cell behavior?

Back

The ability of a solution to cause a cell to gain or lose water.

Front

What is a semipermeable membrane?

Back

A membrane that allows certain molecules to pass through while blocking others.

Front

What occurs in a hypertonic solution?

Back

A cell will shrink as water moves out of the cell.

Front

What is the difference between isotonic and hypertonic solutions?

Back

Isotonic solutions have equal solute concentrations inside and outside the cell, while hypertonic solutions have a higher concentration outside.

Front

What is active transport?

Back

The movement of molecules across a membrane against their concentration gradient, requiring energy.

Front

What is the role of aquaporins in cells?

Back

Aquaporins are proteins that facilitate the transport of water across cell membranes.
