What process occurs when WATER diffuses across a membrane?

• endocytosis
• mitosis
• osmosis
• nuclear fission 

During osmosis

• water moves from high to low concentration
• large or oddly shaped molecules move across a cell membrane
• water moves when energy is used
• proteins are built

Permeable means

• things can pass through
• the concentration levels are different
• it is permanent
• things are stuck
