Front

What is osmosis?

Back

The diffusion of water molecules through a selectively permeable membrane.

Front

What does a selectively permeable membrane do?

Back

Allows certain size substances to enter and leave.

Front

What does cell theory state?

Back

Cells are the basic unit of life.

Front

What type of transport is osmosis classified as?

Back

Facilitated diffusion.

Front

What happens to a cell in a hypotonic solution?

Back

It can swell and burst.

Front

Define diffusion.

Back

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

Front

What is active transport?

Back

The movement of substances against their concentration gradient, requiring energy.

Front

What is equilibrium in the context of cell transport?

Back

A state where the concentration of substances is equal on both sides of a membrane.

Front

What is turgor pressure?

Back

The pressure exerted by water inside the central vacuole against the cell wall.

Front

What is the role of transport proteins?

Back

Facilitate the movement of substances across a cell membrane.
