Answer: osmosis
Explanation: I learned about it
Answer:
The correct answer is osmosis is the movement of water across the membrane;diffusion is the movement of molecules from a higher to lower concentration with or without the presence of membrane.
Explanation:
Diffusion and osmosis are the two most important process of passive transport.Both diffusion and osmosis helps in the movement of water molecules from high water concentration region to region of low water concentration until equilibrium in both sides is reached.
Osmosis needs the presence of a semipermeable membrane to occur.
