Porins are the types of proteins which acts as a pore of large sizes, through which the molecules can diffuse.
They are present in the outer membranes of plastids such as chloroplast, mitochondria and the membranes in bacteria and help in facilitating the passive transport of small-sized protein molecules.
Thus, they help in diffusion.
