A)in the epithelium of an animal's stomach
B)between the smooth endoplasmic reticulum and the rough endoplasmic reticulum
C)between plant cells in a woody plant
D)in the plasma membrane of prokaryotes
E)on the surface of Archaea that adhere to rocks

Tight junctions are found in the epithelium of animals, particularly in areas where tight barriers are needed, such as the stomach, intestines, and bladder. They serve to prevent the diffusion of substances between cells, ensuring that only selective passage of substances occurs.
