Osmosis general

Question 1

What is Osmosis?

Answer 1

Osmosis is the net movement of water molecules from an area of high water potential to an area of low water potential across a partially permeable membrane

Question 2

Osmosis happens… (concentration gradient)

Answer 2

Down a water concentration/potential gradient

Question 3

What does a selectively permeable membrane allow?

Answer 3

A selectively permeable membrane will allow some substances to pass through but not others

Question 4

Why is the cell membrane selectively permeable?

Answer 4

So it can control what enters and leaves the cell
However certain treatments damage the cell membrane, and make it fully permeable (high temps)
