Question

Quizplus · Accepted Answer

Epithelial tissue is a sheet-like layer of cells that is tightly packed with no extracellular matrix in between. Connective tissue has extracellular matrix and is not sheet-like. Adhering junctions and tight junctions are specialized cell junctions found between cells, but do not form a layer of cells. Basement membranes are thin, sheet-like layers of extracellular matrix that are found beneath epithelial tissues.
