Movement into and out of Cells

Movement into and out of Cells

Multiple Choice

What causes diffusion?

• The constant, random motion of molecules

• Magnetic attraction between atoms

• The nuclear forces that hold atoms together

• The tendency of atoms to form chemical bonds with one another

Multiple Choice

Diffusion is the natural movement of molecules from:

• Areas of low concentration to areas of high concentration

• Areas of high concentration to areas of low concentration

• Cold to hot environments

• Gaseous to liquid environments

Multiple Choice

How do the particles move in diffusion?

• From a region of low concentration to a region of high concentration

• From a region of high concentration to a region of low concentration

• From a region of low concentration to a region of low concentration

• From a region of high concentration to a region of high concentration

Multiple Choice

During diffusion

• substances (things) moves from high to low concentration
• water moves when energy is used
• large or oddly shaped molecules move across a cell membrane
• water moves from high to low concentration

Multiple Choice

Multiple Choice

What happens if someone gives you a 90% salt saline drip?

• Your cells will shrivel and you'll die
