The cell junctions called as tight, adhering and gap junctions are found in
Open in App
Solution
The correct option is A Epithelial tissue
Epithelial tissue forms the outermost covering which acts as a protective covering. At tight junctions, the plasma membranes of adjacent cells are closely in contact with each other and do not allow any exchange of material. Gap junctions provide small, reinforced openings between adjacent cells, through which electric currents, ions and small molecules can pass. Adhering junctions connect the lateral membranes of adjacent epithelial cells. They participate in cell-matrix adhesion and are usually located near the apical surface just below the tight junctions. Desmosomes occur only in plants, where they serve to hold two cells together, the small extracellular space between them is filled with fibrous, presumably adhesive material So, the correct answer is 'Epithelial tissue'
