The Egg demo - Osmosis

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

• Selectively Permeable

• Selectively Porous

• Selectively Impermeable

• Selectively Specific

What caused the eggs to become larger or smaller?

• Water going into or out of the egg

• Solutes going into or out of the egg

The egg would get larger if placed in a ____________ solution

• Hypertonic

• Hypotonic

• Isotonic

• Osmotonic

The egg got smaller in the corn syrup. This means that corn syrup is a ____________ solution

• Hypertonic

• Hypotonic

• Isotonic

• Osmotonic

Which type of transport was demonstrated throughout this lab?

• Passive Transport

• Active Transport

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

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

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