Osmosis is the movement of _____ across a membrane.

• food

• energy

• oxygen

• water

Tags

NGSS.MS-LS1-3

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

What is the definition of  Selective Permeability?

• The movement of materials across the cell membrane that requires NO ENERGY from the cell.
  
• The movement of materials through (or across) the cell membrane
  
• The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.
• The movement of molecules from an area of high concentration to a area of low concentration
