Describe diffusion:

• the movement of molecules higher concentration to an area of lower concentration

Identify which molecule is diffusing into the cell.

• A

• B

NGSS.MS-LS2-3

Molecule A cannot diffuse. What is a possible reason why?

• Molecule A is a macromolecule and it is too large to move.

• Molecule A is a building block and it is too large to move.

• Molecule A is a building block and it is too small to move.

• Molecule A is a macromole and it is too small to move.
