ม4 Osmosis

Where will the water go?

• Into the cell
• Out of the cell
• Equally in & out - it's isotonic
• There is no water

A blood cell is placed into the jar, as seen. Where will the water go?

• Into the cell
• Out of the cell
• Equally in & out - it's isotonic
• The water is a lie

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

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

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

When both inside and outside of a cell have the same amount of water it is said that the cell has reached a state of ___________.

• osmosis
• equilibrium
• diffusion
• hypertonic

If you looked at red blood cells under a microscope and saw the blood cells exploded, what would you say happened?

• The cells were placed in a hypotonic solution.
• the solution was isotonic.
• The solution was hypertonic.

The picture below is an example of _________________.

• osmosis

• isotonic

• diffusion

• active transport

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
