Biology EOC Osmosis and Diffusion

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

• Osmosis
• Diffusion
• Active Transport
• Passive Transport

What type of cellular transport uses energy?

• Passive Transport
• Active Transport

Diffusion and Osmosis are examples of...

• Active Transport
• Passive Transport

During diffusion

• substances (things) moves from high to low concentration
• water moves when energy is used
• large or oddly shaped molecules move across a cell membrane
• water moves from high to low concentration

_______ regulates what enters and leaves a cell.  

• Cell Membrane
• Nucleus
• Mitochondria
• Cytoplasm

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.

The picture below is an example of _________________.

• osmosis
• isotonic
• diffusion
• active transport

Passive transport requires no

• concentration gradients
• osmosis
• motion
• energy

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.
