2.2 Cellular Transport

Moving from areas of LOW concentration to areas of HIGH concentration is called?

• Passive Transport
• Active Transport
• Diffusion
• Osmosis

My cells are Shriveled!    What state are my cells in?

• Hypertonic
• Hypotonic
• Isotonic
• Diffusion 

What is the diffusion of water through a selectively permeable membrane?

• active transport
• osmotic pressure
• facilitated diffusion
• osmosis

Diffusion is the movement of particles

• from low to high concentration
• from  high to low concentration
• from equilibrium to areas of high concentration
• all of the above

Facilitated diffusion requires

• no energy
• energy

Placing a cell in an isotonic solution causes the cell to

• shrink
• swell
• stay the same

What type of transport is pictured here?

• exocytosis

• endocytosis

• facilitated diffusion

• diffusion

Particles are too large to enter the membrane.
Need help from channel proteins. No energy required.

• active transport
• passive transport
• facilitated diffusion
• osmosis

The substance that is dissolved in a solution. 

• solute
• solution
• solvent
• solidify

A cell in a hypotonic solution will

• swell
• shrink 
• stay the same size
• impossible to tell
