How do different cells recognize each other?

• Carbs attatched to proteins face out like an ID card so they can recognize each other
• they do not recognize each other

• they have a type of code

• proteins attach to carbs

What is the difference in osmosis and diffusion?

• Diffusion is water and molecules theough a semi permiable membrane osmosis passive diffusion is only water
• they are the same

• osmosis is passive diffusion is active

• there is no difference
