Osmosis Egg Lab

What is diffusion?

• The movement of substances from an area of low concentration to an area of high concentration.

• The movement of substances from an area of low concentration to an area of equal concentration.

• The movement of substances from an area of high concentration to an area of low concentration.

• The movement of substances from an area of high concentration to an area of higher concentration.

Osmosis is...

• The diffusion of gas molecules from high to low concentration!!!

• The diffusion of anything from high to low concentration!!!

• The diffusion of liquids ONLY!!!

• The diffusion of water ONLYl!!!

Membranes that allow on a specific size or type of molecule to pass through is called...

• Selectively Permeable

• Selectively Porous

• Selectively Impermeable

• Selectively Specific

A hypertonic solution results in a cell becoming...

• larger in size (swelling)

• no change in size (stays the same)

• smaller in size (shrinking)

• impermeable to water

A hypotonic solution results in a cell becoming...

• larger in size (swelling)

• no change in size (stays the same)

• smaller in size (shrinking)

• impermeable to water

An isotonic solution results in a cell becoming...

• larger in size (swelling)

• no change in size (stays the same)

• smaller in size (shrinking)

• impermeable to water

What is the title of this lab?

• Egg Yolk Osmosis Lab

• Egg White Osmosis Lab

• Egg Shell Osmosis Lab

• Egg Osmosis Lab

What is a good "rule of thumb" to help remember how water moves across cell membranes?

• "Water likes to dissolve"

• "Water likes to dilute"

• "Water likes to decompose"

• "Water likes to diffuse"

If a membrane is determined to be impermeable the it...

• will allow all substances to pass through...

• will allow only water to pass through...

• will block everything except water...

• will block everything from passing through...
