• From an area of low concentration to high concentration

• only in liquids

• From an area of high concentration to low concentration

Sugar molecules can enter cells through the process of…

• Exocytosis

• Facilitated diffusion

• Osmosis

• Ion pumps

Molecules that are too large to be moved across a cell membrane can be removed from the cell by…

• Diffusion

• Exocytosis

• Lipid Carriers

• Osmosis

A plant cell is placed in a hypotonic solution. What will happen to the plant cell?
