Cell Transport

The picture below is an example of _________________.

• osmosis
• isotonic
• diffusion
• active transport

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

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 
  

All living things want to remain in...

• chaos
• homeostasis
• limbo
• plasmolysis

Why will a plant die if you water it with a salt water?

• hypotonic solution
• hypertonic solution
• isotonic solution
• silly solution

if you put a plant in salt water it will ...

• swell because water diffuses into the cells
• swell because water diffuses out of the cell
• shrivel because water diffuses out of the cell

The movement of particles from an area of high to low concentration is known as--

• Passive Transport

• Active Transport

What is it called when large molecules move across the cell membrane from an area of high concentration to an area of low concentration through a protein channel?

• Diffusion

• Osmosis

• Active Transport

• Facilitated Diffusion
