Osmosis and Diffusion Concepts

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

The diffusion of water through a semi-permeable membrane is called?

• Osmosis
• Cell wall
• Diffusion
• Respiration

In the given scenario what will happen to the organism: salt is poured onto eggplant.

• Water will move out of the eggplant cells and the cells will shrink.
• Water will move out of the eggplant cells and the cells will swell.
• Water will move into the eggplant cells and the cells will swell.

In the given scenario what will happen?  An egg is placed in pure water for 48 hours.

• The egg will gain water and swell.
• Water will move in and out of the cell equally, and the cell with neither shrink nor swell.
• The egg will lose water and shrink.

An animal cell placed in a hypertonic (salty) solution will

• Shrink
• Swell
• Stay the same

Ideally, your cells should be in a(n) _______ solution

• Hypertonic
• Hypotonic
• Isotonic
• Cola

The picture below is an example of _________________.

• osmosis
• isotonic
• diffusion
• active transport

When both inside and outside of a cell have the same amount of water it is said that the cell has reached a state of

• Osmosis
• Diffusion
• Equilibrium

Passive transport requires no

• concentration gradients
• osmosis
• motion
• energy

Osmosis

• diffusion of water molecules through a semi-permeable mebrane from an area of low concentration to an area of high concentration
• the diffusion of particles from an area of high concentration to an area of low concentration
• diffusion of water molecules through a semi-permeable membrane from an area of high concentration to an area of low concentration
• the diffusion of particles from an area of low concentration to an area of high concentration
