Answer: D) Different types of epithelial tissue may be identified by the shape and overall structure of the cells that make up the tissues.
Explanation:
Epithelial cells form a layer structure which covers most of the surfaces of the body. These cells perform variety of functions and exhibit different shapes, size and arrangement which makes up different tissues. For example columnar tissues (column like cells), cuboidal tissues (cube like cells) and others.
Hence, these epithelial tissues can be identified in a microscopic slide.
