Match the following

• Endocytosis

• Particle movement from low to high

• Passive transport/Simple diffusion

• A cell forms a vacuole around material

• Exocytosis

• Movement from high to low concentration

• Active transport

• A cell expels a vacuole of material

• Facilitated diffusion

• Movement from high to low via protein channel

Osmosis Practice Activity: For the first diagram, what will happen?

• Water will flow: OUT OF THE CELL

• The cell will SHRINK

• Water will flow: INTO THE CELL

• The cell will BURST
