Biology 7.4 Cellular Transport

This is the movement of particles from an area where there are many particles of the substance to an area where there are fewer particles of substance:

• Active Transport

• Exocytosis

• Endocytosis

• Diffusion

True or False: Cellular transport moves substances within the cell and moves substances into and out of the cell.

• True

• False

True or False: Cellular transport is designed to maintain homeostasis.

• True

• False

This is state has continuous movement but no overall change:

• Diffusion

• Dynamic Equilibrium

• Facilitated Diffusion

• Osmosis

This is another form of transport that uses transport proteins to move other ions and small molecules across the plasma membrane:

• Diffusion

• Dynamic Equilibrium

• Facilitated Diffusion

• Osmosis

True or False: Facilitated Diffusion requires additional input of energy.

• True

• False

This is the difference in concentration of particles:

• Diffusion

• Concentration Gradient

• Particle Spectrum

• Isotonic Solution

This is the diffusion of water across a selectively permeable membrane:

• Osmosis

• Select Diffusion

• Concentration

• Hypotonic Solution

True or False: An isotonic solution has the same concentration of water and solutes as the cell in it.

• True

• False

True or False: Cells do NOT retain their same shape in isotonic solutions.

• True

• False
