When particles move from areas of high concentration to areas less concentrated, this has taken place.

• diffusion

• mitosis

• endocytosis

• photosynthesis

What process occurs when WATER diffuses across a membrane?

• endocytosis

• mitosis

• osmosis

• nuclear fission 

Which diagram best shows the end result of diffusion?

• F

• G

• H

• J

Why are diffusion and osmosis important to cells?

• It allows them to take in materials/substances without using energy.

• It allows them to reproduce.

• It allows them to absorb sunlight.

• It allows cells to use all energy.

What does selectively-permeable mean?

• Nothing gets through

• The cell lets only large substances through

Which way will the water molecules move during osmosis?

• Out of the cell, so the cell shrinks.

• Out of the cell, so the cell swells.

• Into the cell, so the cell shrinks.

• Into the cell, so the cell swells.
