Osmosis

Osmosis

'Osmosis is the net movement of water molecules across a partially permeable membrane from a region of higher water concentration to a region of lower water concentration'

Partially permeable membrane - Allows smaller water molecules through

Water molecules can pass both ways through the membrane - water molecules move randomly all the time

Where there is more water molecules, there is a steady flow to the region where there is less water molecules

More concentrated sucrose becomes more dilute - the sies are trying to even up its concentration

Osmosis is a type of diffusion

When a plant is watered the cells draw in water by osmosis and become plump and…
