Question

this type of junction prevents fluids from leaking between adjoining cells:
plasmodesmata
tight junction
gap junction
adhering junction

Explanation:

Tight junctions form a continuous seal between adjacent cells, preventing the leakage of fluids and solutes between them. Plasmodesmata are channels in plant cells for communication. Gap junctions allow for the passage of small molecules between cells. Adhering junctions provide cell - to - cell adhesion but do not prevent fluid leakage like tight junctions.

Answer:

tight junction
