Cell Membrane Transport

Diffusion of water through a selectively permeable membrane (high to low concentration) is called:

• Phagocytosis

• Filtration

• Osmosis

• Facilitated Diffusion

The movement of materials through a cell membrane using energy is known as:

• active transport

• osmosis

• facilitated diffusion

• passive transport

What process is illustrated by the movement of water from salt water to fresh water through a semipermeable membrane?

• osmosis

• Endocytosis

• Exocytosis

• diffusion

A solution whose solute concentration is equal to the solute concentration inside a cell is called:

• Hypertonic Solution

• Hypotonic Solution

• Merotonic Solution

• Isotonic Solution

What type of solution, when surrounding a cell, will cause the cell to take up water?

• Hypotonic Solution
