Which best describes the difference between osmosis and diffusion? osmosis is the movement of particles from a high to low concentration, while diffusion is the movement of water from a low particle concentration to a high particle concentration. diffusion is the movement of particles from a high to low concentration, while osmosis is the movement of water from a low particle concentration to a high particle concentration. diffusion is the movement of particles from a low to high concentration, while osmosis is the movement of water from a high particle concentration to a low particle concentration. osmosis is the movement of particles from a low to high concentration, while diffusion is the movement of water from a high particle concentration to a low particle concentration.

The answer should be the third option.
Diffusion can be the movement of any fluid, liquid or gas, from a region of higher concentration to the region of lower concentration. but osmosis is only the movement of water molecules, from a region of higher water potential to lower water potential. Note that osmosis requires a semi permeable membrane.

The differences between osmosis and diffusion is that, Diffusion is the movement of particles from a high to low concentration, while osmosis is the movement of water from a low particle concentration to a high particle concentration.

Further Explanation; Transport in living organismsPlants and animals use various processes to transport materials from one point to another. There are classified as either passive transport or active transport. Passive transport It is a type of transport that does not involve the use of energy to aid movement of substances in living organisms. Passive transport involves free movement of substances and through special types of transporters or carriers. Types of passive transport includes; simple diffusion, facilitated diffusion, osmosis, and mass flow among others. Active transport  It is a type of transport in living organisms that involves movement of substances against a concentration gradient and involves use of energy in form of ATP to aid transport of substances. Osmosis  Osmosis is a special diffusion that involves the movement of water molecules from a region where they are highly concentrated to a region where they are lowly concentrated through a semipermeable membrane. It may also refer to the movement of water molecules from a region of low particle concentration to a region of a high particle concentration. Diffusion  Diffusion is a type of passive transport that involves movement of particles from a region of high concentration to a region of low concentration. Diffusion involves movement of molecules of substances other than water.
