Chapter 5.7, Problem 1C

Summary Introduction

To determine: The way by which desmosomes and tight junctions are functionally similar.

Concept introduction: Cell junctions are multiprotein structures that link cells to each other and to the environment. They help in cell–cell communication and signal transduction in multicellular organisms such as animals and plants. Examples for cell junctions in animal cells are anchoring junctions, tight junctions, and gap junctions whereas plant cells are connected by plasmodesmata.
