Diffusion Lab Flashcard A

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.

Front

What is the result of diffusion in a cell with 24 molecules when the membrane is permeable?

Back

After diffusion, there would be 12 molecules inside and 12 molecules outside the cell.

Front

Which diagram best shows the end result of diffusion?

Back

Diagram J best shows the end result of diffusion.

Front

What is the process shown in the picture?

Back

The picture is an example of diffusion.

Front

Is the statement 'Diffusion is the movement of molecules through a semi-permeable membrane from an area of higher concentration to an area of lower concentration' true or false?

Back

True.

Front

What is the concentration gradient?

Back

The concentration gradient is the difference in concentration of a substance between two areas.

Front

What factors affect the rate of diffusion?

Back

Factors include temperature, concentration gradient, and the size of the molecules.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules through a semi-permeable membrane.

Front

What is an isotonic solution?

Back

An isotonic solution is one where the concentration of solutes is the same inside and outside the cell.

Front

What is active transport?

Back

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