Cell Membrane Cellular Transport

What is the diffusion of water through a selectively permeable membrane?

• active transport

• osmotic pressure

• facilitated diffusion

• osmosis

Diffusion is the movement of particles

• from low to high concentration

• from  high to low concentration

• from equilibrium to areas of high concentration

• all of the above

What is it called when a cell is placed in a solution that has a greater concentration on the outside of the cell than inside?

• Hypotonic

• Hypertonic

• Isotonic

• Osmosis

When there is the same concentration of solute molecules outside the cell as inside.

• Hypotonic

• Hypertonic

• Isotonic

• Homeostasis

Which type of transport does NOT require energy?

• osmosis

• passive transport

• diffusion

• All are correct

During osmosis

• water moves from high to low concentration

• large or oddly shaped molecules move across a cell membrane

• water moves when energy is used

• proteins are built

A person should never drink salty water because their cells would
