In vertebrates, there are three major types of cell junction:1. Adherens junctions, desmosomes and hemidesmosomes (anchoring junctions.)2. Gap junctions (communicating junction)3. Tight junctions (occluding junctions)Your question most likely is for the tight junction but more information in the question would be helpful.
plasmodesmata tight junctions desmosomes gap junctions the plasmodesmata is the only cell junction in the plant cells.. and the other three cell junctions are in the animal cells...
Desmosomes are cell structures that anchor neighboring cells together.Channels that allow water and other molecules to flow between neighboring cells are not desmosomes, but gap/communicating junctions.
Tight junction - impermeable junction that encircles the cell Desmosome - anchoring junction scattered along the sides of cells Gap junction - a nexus that allows chemical substances to pass between cells

Cell junctions in plants are called Plasmodesmata while communicating junctions in animal cells are gap junctions
c
There are gap junctions which help the cells communicate with one another.
Tight junctions, or zonula occludens, are the closely associated areas of two cells whose membranes join together forming a virtually impermeable barrier to fluid

Impermeable means that stuff can't go through it. Wax is impermeable to water. Paper towels are not. Glass is impermeable to air. Mesh cloth is not. Some things are impermeable to one thing but not another. Clear plastic is impermeable to water and air, but not light. Lead metal is impermeable to x-rays, but not heat. Which layer is impermeable depends on what it is impermeable to.

Junctions on roads are intersections.
