What are the characteristics of epithelium tissue?
Cellularity. Epithelia are composed almost entirely of cells. Specialized contacts. Adjacent epithelial cells are directly joined at many points by special cell junctions.Polarity. Support by connective tissue. Avascular but innervated. Regeneration.

What are different types of epithelial tissue class 9?
Types of Epithelial TissueSquamous Epithelium – These are thin, flat cells that are closely packed. Cuboidal Epithelium – These cells are cuboidal in shape. Columnar Epithelium – The columnar epithelium has cells that are pillar-like and column-like.
