Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which type of cellular junction from a “quilted seal” between cells?
A
Tight junctions
B
Desmosomes
C
Gap Junctions
D
None of the above
Explanation: 

Detailed explanation-1: -Plasmodesmata are intercellular junctions between plant cells that enable the transportation of materials between cells. A tight junction is a watertight seal between two adjacent animal cells, which prevents materials from leaking out of cells.

Detailed explanation-2: -Tight junctions (also called zonula occludens or occluding junctions) are a type of cell junction characterized by forming an adhesion complex between two neighboring cells serving as a tight seal between the cells. The tight junctions are essentially a protein complex between two cells.

Detailed explanation-3: -Communicating (gap) junctions Communicating junctions, or gap junctions allow for direct chemical communication between adjacent cellular cytoplasm through diffusion without contact with the extracellular fluid.
