Biology Osmosis and Diffusion

Where will the water go?

• Into the cell
• Out of the cell
• Equally in & out - it's isotonic
• There is no water

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

• The water is a lie

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

What do the brown structures represent?

• Phospholipids
• Glycoproteins
• Channel Proteins 
• Cyctoskeleton Filaments

What is the movement of molecules from an area of high concentration to low concentration? 

• Mitosis
• Diffusion
• Passive Transport
• Active Transport

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.

Osmosis is

• the diffusion of water molecules through a semi-permeable membrane from an area of low concentration to an area of high concentration

• the diffusion of particles from an area of high concentration to an area of low concentration

• the diffusion of water molecules through a semi-permeable membrane from an area of high concentration to an area of low concentration

• the diffusion of particles from an area of low concentration to an area of high concentration

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.
