Question

The tissue covering the external surface of the animal and the internal surface of the visceral organ is
(a)Adipose tissue
(b)Connective tissue
(c)Cartilaginous tissue
(d)Epithelial tissue

Answer 1

Hint: Tissue is also known as vascular tissue which is closely packed without any intercellular spaces and lies on the basement membrane. It is mainly of two types and can be ectodermal, mesodermal, or endodermal in origin.

Complete answer:
Epithelial tissue covers the outer surface of organs and blood vessels throughout the body as well as the inner surfaces of cavities in many internal organs.

Additional Information: -Epithelial tissue is based on the cell layers divided into two types- simple epithelium tissue that is present in single-layered and stratified epithelial tissue that is present in more than one layered.
-Epithelial tissue based on the shape of the cell divided into three types- squamous epithelium or flattened cells, cuboidal epithelium or cubic cell, and columnar epithelium and columnar cells.
-Based on the cell layer and shape of the cell the different types of epithelial tissue are-
Simple squamous epithelial tissue
Simple cuboidal epithelial tissue
Simple columnar epithelial tissue
Pseudostratified epithelial tissue
Stratified squamous epithelial tissue
Stratified cuboidal epithelial tissue
Stratified columnar epithelial tissue
Transitional epithelium epithelial tissue

So, the correct answer is, ‘ Epithelial tissue.’

Note: -The study of tissue is known as histology.
-The single-layered flat cells are present in kidneys, lungs, the lining of heart, blood vessels, etc which helps infiltration or diffusion of small molecules.
-The single-layer cuboidal shaped cells tissue is present in the salivary gland, kidney tubules, and ovary surface specialized for secretion and absorption.
-The rare multi-layered column-shaped cell tissue is present in parts of the pharynx, uterus, and vas deferens as a secretive and protective layer.
