Question

Who permit the rapid diffusion of small,water soluble molecules between cytoplasm of adjacent cells?

Answer 1

Specialized cell juction occur at points of cell-cell and cell-matrix contact in all tissues, and they are particularly plentiful in epithelia. Cell junctions are best visualized using either conventional or freeze frecture  electron microscopy , which reveals that the interacting plasma membranes (and often the underlying cytoplasm and the intervening intercellular space as well) are highly specialized in these regions.

Answer 2

Cell junction permits the rapid diffusion of small, water-soluble molecules between the cytoplasm of adjacent cells.

Explanation:

• Cell junctions are microscopic structures where the adjacent cells come very close in a tissue with minimal wall structure or membrane between them.
• These can be visualized only under high-resolution microscopes and differential techniques.
• They allow the rapid diffusion of small, water-soluble molecules between the cytoplasm of adjacent cells.
