Question

How are osmosis and diffusion alike

Answer 1

Answer:

• Osmosis and diffusion are alike in a way that in both motion of molecules/water is in the direction of concentration gradient.
• Osmosis and diffusion are passive process (energy free).

Explanation:

• Osmosis is the process of movement of water from high concentration of water to low concentration of water across the permeable membrane.
• Diffusion is the transport of materials from high concentration to low concentration.
• Concentration gradient means the Movement always from higher to lower concentration of materials.
• So in the osmosis and diffusion movement is always from high to low concentration.

Answer 2

They both move molecules from high to low concentration, they both usually move things across a membrane, but diffusion is not always across a membrane. It can just be molecules moving.
