Cellular Transport Mechanisms

There are two types of cellular transport. What are they?

• Chlorophyll

• Active

• Solution

• Passive

Which type of cellular transport uses energy?

• Passive

• Active

Passive transport-What are the two ways that molecules can move passively into, out of, and through organisms?

• Diffusion

• Exocytosis

• Endocytosis

• Osmosis

Active transport-What are the two ways that molecules can move actively into, out of, and through organisms?

• Diffusion

• Endocytosis

• Exocytosis

• Osmosis

With passive transport, molecules move either by diffusion or osmosis. In both cases, molecules move from a _______ concentration to a ______ concentration.

• Higher to Lower

• Lower to Higher

Which form of passive transport refers to the movement of water molecules from a higher concentration to a lower concentration through a semipermeable membrane?

• Diffusion

• Osmosis

True or False: Solutions can be either hypertonic, hypotonic, or isotonic?

• True

• False

If a solution is hypertonic, water will move _____ the solution.

• in to

• out of

If a solution is hypotonic, water will move _____ the solution.

• in to

• out of

If a solution is isotonic, water will move _____ both solutions.

• in to

• out of

• flows equally between
