What makes it necessary for animal cells although they have no cell walls to have intercellular junctions?

Answer 1

Large molecules, especially proteins, do not readily get through one, much less two adjacent cell membranes

Answer 2

Intercellular junctions are necessary for animal cells to maintain tissue structure, provide communication between cells, and regulate the passage of molecules. Without cell walls, intercellular junctions are crucial for holding cells together, allowing them to function as a coordinated unit. Additionally, they facilitate the exchange of signals and nutrients between cells.

Answer 3

Maintenance of tissue integrity and barriers to fluid leakage requires cells to adhere tightly to one another.

Answer 4

it makes the cells more pliable, and more stretchy, like if you pinch your skin or rub it around, it moves more easily that the stiff leaves of plants.
