The function of epithelium tissue is mainly to protect the tissues below it from desiccation and radiation. The other functions include secretion of hormones into the blood system and provide sensation.
In the kidney, simple squamous epithelium lines the Bowman's capsule and the glomerulus. In this case, the ability of simple squamous epithelium to provide rapid filtration and diffusion is instrumental to the kidney's function, as the kidney filters about 180 liters of blood per day !
Bryophytes lack any sort of vascular tissue therefore they are incapable of transporting water over long distances. Because of this, they grow short to the ground and in moist environments where water is readily available to them.
Non Vascular plants such as moss and liverwort lack vascular tissue or transport tissues. The plants are dependent on osmosis and diffusion for the movement of water and nutrients through their cells. These plant also lack a true root system, stems, or leaves without the vascular tissue to support them.

Fish use diffusion and osmosis to keep their tissue healthy. Diffusion starts in the gills and for some small molecules can happen in the gut walls as well.

Diffusion occurs across simple epithelial tissue. These are only one layer.

diffusion from red blood cells in capillaries to the tissue cells
The definition of apparent diffusion coefficient is a measure of the extent of diffusion of the water molecules that are in tissue. It is a term used in reference to an MRI.
