Define Osmosis.

A type of cellular transport is shown.

Which description best identifies this type of cellular transport?

• Active transport, because energy is being used to move molecules against the concentration gradient

• Facilitated diffusion, because energy is being used to move molecules with the concentration gradient

• Osmosis, because energy is not being used to move molecules with the concentration gradient

• Endocytosis, because energy is not being used to move molecules against the concentration gradient

If a cell cannot produce energy, what type of transport can it no longer perform?

• Simple diffusion

• Facilitated Diffusion

• Osmosis

• Passive Transport

• Active Transport

The sodium potassium pump is an example of ______________________ transport.

• Active

• Passive

• Both Active and Passive

• None of the above

Match the following vocabulary terms and definitions.

• Isotonic

• Low concentration; the solution has less solutes than the cell, causing water to move into the cell and out of the solution.

• Hypertonic

• Same concentration; the solution and cell have equal concentration of solutes (particles), so water moves equally between the cell and solution.

• Hypotonic

• High concentration; the solution has more solutes than the cell, causing water to move out of the cell and into the solution.

​ (a)   brings glucose into cells.

• Insulin

• Glucagon
