Front

What is the most basic unit of life?

Back

Cell

Front

Describe 3 major differences between a prokaryotic cell and eukaryotic cell: Nucleus, size, organelles

Back

Nucleus, size, organelles

Front

Identify the differences between animal and plant cells.

Back

Cell wall, chloroplasts, large vacuole

Front

List all of the different ways to refer to the cell membrane.

Back

Plasma membrane, phospholipid bilayer

Front

What is the cell membrane made of?

Back

Proteins and lipids

Front

Know the difference between hydrophobic and hydrophilic. How do these 2 properties help the cell membrane function?

Back

They allow selective permeability

Front

What does semi-permeable mean?

Back

Allows some substances to pass.

Front

Describe the difference between passive transport and active transport.

Back

Active transport requires energy, passive transport does not.

Front

What are the 3 types of passive transport?

Back

Diffusion, osmosis, facilitated diffusion

Front

Describe the difference between diffusion and facilitated diffusion. List some particles that travel through diffusion and some molecules that travel through the membrane by facilitated transport.

Back

Diffusion is passive, facilitated uses proteins.
