No, diffusion does not require help from vesicles. Diffusion is the movement of particles from an area of high concentration to an area of low concentration, driven by concentration gradients. Vesicles, on the other hand, are membrane-bound structures that transport materials within cells through processes like endocytosis and exocytosis.
Facilitated diffusion is a type of passive transport where specific molecules are transported across the cell membrane with the help of transport proteins. Unlike simple diffusion, facilitated diffusion requires the presence of these proteins to facilitate the movement of molecules across the membrane.
Diffusion can help discover a fire by carrying the smell of smoke to other areas, alerting nearby individuals of the fire's presence. Additionally, diffusion of heat can raise the temperature in surrounding areas, serving as a warning sign of a fire nearby.
Simple diffusion does not involve the use of transport proteins and relies on the concentration gradient of molecules for movement across the membrane. Facilitated diffusion, on the other hand, requires specific transport proteins to help facilitate the movement of molecules across the membrane, often against their concentration gradient.

Evaporation and diffusion
Veins have to carry blood for diffusion, therefore they muse be thin in order for diffusion to easily occur.
Diffusion allows the cell to passively transport the waste chemicals out side of the cell so that the cell is not harmed.
