Final answer:
Adherens junctions require cadherins and actin filaments to create a strong, cohesive bond between cells, forming the epithelial tissue with proper structure and function.
Step-by-step explanation:
The proteins required for the adherens junction are cadherins, which are the adhesion molecules that play a crucial role in binding cells together to form tissues. These cadherins are embedded in plaque proteins within the cell membrane, connecting across the intercellular space to other cadherins of adjacent cells. Inside the cell, these plaque proteins are linked to actin filaments, which are part of the cytoskeleton, thereby providing strength and stability to the tissue layers. Adherens junctions can be visualized as the belt desmosomes (zonula adherens) or as spot desmosomes (macula adherens), where they contribute to the overall integrity and shape of the epithelial tissue.
