Summary Introduction
Introduction: In a multicellular organism, cells are linked to each other by specialized structures called cell junctions. Plant cells are connected by middle lamella and plasmodesmata. Plasmodesmata are defined as passageways or pores between cell walls of adjacent cells that can be opened or closed. When opened, they allow the direct diffusion of ions, water, and small molecules between the cytosols of adjacent cells.
