B1.7 Osmosis Flashcards
What is osmosis?
A special type of diffusion where only water molecules
diffuse through semi permeable membrane.The molecules move from a place of high concentration
to a place of low concentration.
What is a semi permeable membrane?
A membrane which
Only let some through and not others
What is a dilute solution?
A solution that contains more parts water than sugar.
What is a concentrated solution?
A solution that contains more sugar parts water than water.
What happens when the water is hypertonic to the cell?
Water goes out of the cell
What happens when the water is hypotonic?
WATER GOES IN
What is an isotonic solution?
external concentration(out cell) = internal concentration(in cell)
what is a hypertonic solution?
external concentration(out cell) > internal concentration(in cell)
What is a hypotonic solution?
external concentration(out cell) < internal concentration(in cell)
