Passive Transport Review

Front

What is the primary function of the cell membrane?

Back

Regulates which materials enter and leave the cell.

Front

What happens to diffusion in cells when equilibrium is reached?

Back

Diffusion stops.

Front

What type of solution is a cell in if no osmosis is observed over time?

Back

Isotonic solution.

Front

What term describes the stability of a cell's internal environment?

Back

Homeostasis.

Front

What is diffusion?

Back

The movement of molecules from an area of high concentration to an area of low concentration.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is a hypotonic solution?

Back

A solution with a lower concentration of solutes compared to the inside of the cell.

Front

What is a hypertonic solution?

Back

A solution with a higher concentration of solutes compared to the inside of the cell.

Front

What does it mean for a cell to be in equilibrium?

Back

The concentration of solutes is equal inside and outside the cell.

Front

What role do transport proteins play in passive transport?

Back

They help facilitate the movement of substances across the cell membrane without using energy.
