Question
Chapter 10.2, Problem 1CC
Summary Introduction
To determine: The anchoring junctions for cell-to-cell junctions and cell-to-ECM junctions.
Introduction: In a multicellular organism, cells are linked to each other by specialized structures called cell junctions. Animal cells have a more varied group of cell junctions than plant cells, as they lack a cell wall. Three types of junctions are found between cells in animals. These are anchoring junctions, tight junctions and gap junctions.
