Osmoregulation

Osmosis is the movement of _____ across a membrane.

• food
• energy
• oxygen
• water

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

 An animal cell placed in a hypertonic (salty) solution will

• Stay the same
• Shrink- get smaller
• Swell- get bigger
