Egg Osmosis Lab

What type of cellular transport will this lab demonstrate?

• active transport

• endocytosis

• passive transport

• exocytosis

What happens to an animal cell when it is placed in a hypotonic solution?

• water will leave the cell and the cell will shrink

• water will enter the cell until it lyses

• water will go in and out of the cell equally

• nothing will happen to the cell

What happens to a cell when it is placed in a hypertonic solution?

• nothing will happen to the cell

• the cell will shrink because water will leave the cell

• the cell will lyse because water will enter the cell

• the cell will grow because water is leaving the cell

What happens to a cell when it is placed in a solution where the water concentration is equal to that of the inside of the cell?

• Water will move in and out of the cell equally and the cell will stay the same.

• All the water stays where it is and the cell stays the same.

• Water will move into the cell and the cell will shrink.

How much vinegar should you pour over each egg?

• 50ml

• enough to cover the egg

• 100 ml

• until the cup is half full

What is this lab going to demonstrate?
