Osmosis Lesson

What is the diffusion of water only across a cell or semi-permeable membrane?

• Osmosis

• Diffusion

• Active Transport

• Passive Transport

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

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.

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.

What is the process by which water moves across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration?

• Diffusion

• Active transport

• Osmosis

• Filtration

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.

A blood cell is placed into the jar, as seen. Where will the water go?

• Into the cell

• Out of the cell

• Equally in & out - it's isotonic

• The water is a lie
