Diffusion, facilitated diffusion, osmosis, active transport

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

Ideally, your cells should be in a(n) _______ solution

• Hypertonic
• Hypotonic
• Isotonic
• Cola

The picture below is an example of _________________.

• osmosis
• isotonic
• diffusion
• active transport

_______ regulates what enters and leaves a cell.  

• Cell Membrane
• Nucleus
• Mitochondria
• Cytoplasm

The cell below is in a _________ solution.

• Hypotonic
• Hypertonic
• Isotonic

Which cell is placed into a hypotonic environment? 

• A
• B
• C
• D

What is diffusion?

• when molecules move 
• when molecules move from a high concentration to a low.
• no movement 
• molecules move everywhere

The number of molecules moving one direction minus the number of molecules moving in the other direction.

• equilibrium

• dynamic equilibrium

• net movement

Way to display that molecules are moving from an area of high concentration to an area of low concentration.

• concentration gradient

• concentration

• [high] --> [low]

What type of transport is this?

• facilitated diffusion
• active transport
• diffusion
• osmosis
