What is the difference between osmosis and diffusion?
BARSIC [14]

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.

Pllzzz help i will give 20 points if u answer correct
Nana76 [90]
Passive transport means the cell does not have to spend energy to move gasses and fluids. the gasses or liquids go from a higher concentration to a place of lower concentration. Think about shaking a can of soda. There's a lot of pressure that builds up in the soda. When you open the soda, all of the pressure escapes to an area of lower pressure outside of the can. This is called diffusion. Osmosis is another form of passive transport. For example, in water osmosis, the water goes from a less salty solution to a more salty solution. 

The correct answer is A. Diffusion and osmosis.

hope this helps =)
