Cell Transport

What process occurs when WATER diffuses across a membrane?

• endocytosis

• mitosis

• osmosis

• nuclear fission 

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

• diffusion

• mitosis

• endocytosis

• photosynthesis

What is diffusion?

• when molecules move 

• when molecules move from a high concentration to a low.

• no movement 

• molecules move everywhere

Permeable means

• things can pass through

• the concentration levels are different

• it is permanent

• things are stuck

Movement of particles from high to low concentration.
