Osmosis

What protects carrot cells from swelling too much when it rains?

• They don't swell because rain is absorbed by the roots.
• They have pores in their cell membranes that keep them from swelling.
• The rain water is hypertonic to the cells so the cells lose water.
• They have cell walls that keep them from swelling too much.

 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.

 If a cell containing 5% salt is placed into a glass of water with 20% salt, the water is _______ compared to the cell.

• hypertonic-
• hypotonic
• isotonic

Which way will the water molecules move during osmosis?

• Out of the cell, so the cell shrinks.
• Out of the cell, so the cell swells.
• Into the cell, so the cell shrinks.
• Into the cell, so the cell swells.
