Osmotic Processes

This egg has shrunk (gotten smaller), what type of solution was it placed in?

• hypotonic solution

• hypertonic solution

• isotonic solution

• active transport

A HYPOTONIC solution has a ______________ concentration of solute (dissolved stuff) compared to inside the cell.

• lower

• equal

• higher

If a cell is placed in a HYPOTONIC solution, water will move _________ of the cell, causing it to ___________.

• into, swell
• out of, shrivel
• in and out of the cell, stay the same

The arrows in this diagram of a cell in hypertonic solution show

• the flow of energy

• the direction water molecules will move

• the direction protein molecules will diffuse

The movement of water molecules out of a cell and into an environment with high salt concentration is

• facilitated diffusion

• osmosis

• phagocytosis

• exocytosis

Which type of molecules can diffuse across a cell membrane without using energy?

• H₂O, only

• H₂O, O₂, and CO₂

• proteins and polysaccharides

Is it safe to drink salt water?

• Yum, so salty!

• No, you could die of dehydration.
