|
Plant cells, surrounded by a cell wall, do not contact each other through wide areas of plasma membrane the way that animals cells can. They do, however, have places where a hole exists to allow direct cytoplasmic exchange between two cells. These plant cell features are known as
|
|
vacuoles.
|
|
|
plasmodesmata.
|
|
|
gap junctions.
|
|
|
tight junctions.

Explanation:
Detailed explanation-1: -The cells are attached to each other by cell-cell adhesions, which bear most of the mechanical stresses. For this purpose, strong intracellular protein filaments (components of the cytoskeleton) cross the cytoplasm of each epithelial cell and attach to specialized junctions in the plasma membrane.
Detailed explanation-2: -A plasmodesma is a channel between two adjacent plant cells’ cell walls. Plasmodesmata allow materials to pass from one plant cell’s cytoplasm to an adjacent cell’s cytoplasm.
