They both follow the concentration gradient i.e. require no energy for the process to occur.
Diffusion is the movement of particles from an area of higher concentration to lower concentration.
See Brownian motion.
Osmosis is the movement of WATER particles across a semi-permeable membrane from an area of higher concentration to the lower concentration in the effort to reduce the solute concentration.
To understand the structural similarities, one has to understand the functional similarities. The most obvious similarity is that they are both involved with transport via diffusion. So the structural similarities would be those that facilitate this. eg. thin epithelium, large blood supply.
Osmosis is a basic process in which concentrated solution diffuses to less concentrated through a membrane. Dialysis is filtering of unwanted chemicals etc from the blood of a diabetic patient employing a similar process.
Osmosis is the diffusion of water through a membrane. Diffusion is when particles move from a higher concentration to a lower concentration without the use of any energy. So, in the movie, Osmosis Jones is really a white blood cell (a cell that combats "evil" disease or illness. The the movie would have been titled fine as Osmosis Jones if Osmosis simple diffused from one place to another inside the body. However, that would have been really boring and the studios would have lost their shirts!
what is the similarities between the ulna and the radius
similarities
Osmosis and diffusion are both processes that involve the movement of molecules from an area of high concentration to an area of low concentration. They are both passive processes that do not require energy input from the cell.
Osmosis is a type of diffusion that involves the movement of water molecules across a selectively permeable membrane. Both osmosis and diffusion involve the movement of molecules from an area of high concentration to an area of low concentration. The key difference between the two processes is that diffusion refers to the movement of any type of molecule, while osmosis specifically refers to the movement of water molecules.
The relationship is that osmosis is the diffusion of water throught a selective permeable membrane.
Both osmosis and diffusion are passive transport processes that move molecules from an area of high concentration to an area of low concentration. Additionally, both osmosis and diffusion do not require energy input from the cell.
Diffusion and osmosis are passive and do not require energy.

diffusion and osmosis are types of ways to get materials into or out of a cell
The differences between diffusion and osmosis are really just that osmosis takes place with water and through a membrane. Diffusion is just the spread of molecules from high concentration to low. Osmosis is diffusion of water through a membrane.
The key difference between osmosis and diffusion is that osmosis specifically refers to the movement of water across a semi-permeable membrane, while diffusion is the movement of molecules or particles from an area of higher concentration to an area of lower concentration. Osmosis involves the movement of only water molecules, while diffusion can involve any type of molecule or particle.
osmosis is the movement of water across the plasma or cell membrane
