A) are fine channels across the cell wall that link the plasma membranes and cytosols of adjacent plant cells.
B) connect and support the cell walls of adjacent plant cells through networks of cytoskeletal elements.
C) are integrin protein links similar to tight junctions in animal cells, which maintain the correct location of different membrane proteins.
D) are transmembrane protein channels that connect adjacent plant cells and allow ions to cross freely between them.
E) link cell walls to form tight barriers that prevent the free movement of molecules through the interstitial spaces between plant cells.
