Physical attachment between cells and extracellular matrix is critical in both animals and plants because it imparts rigidity and strength to tissues and organs. However, junctions between cell‐cell or between cell‐matrix are diverse in structure and play roles beyond providing physical support. Column “X” lists some of the cell junctions and column “Y” lists their characteristic functions

D.

Desmosomes 

iv.

allows passage of small molecules but not macromolecules (with some exceptions) in plants.
