• Epidermis

• Epithelium tissue

• Muscular tissue

• Nervous tissue

Answer explanation

The tissue that covers the body of an animal and provides external protection is called epithelium tissue.

Which of the following statement is not true?

• The epithelial tissue present in the animal body is the protective tissue.

• The lining of alveoli, oesophagus, blood vessels and kidney tubules all are made up of epithelial tissue.

• Between the epithelial cells many intercellular spaces are present.

• Layers of epithelial tissue are permeable in nature.

Answer explanation

We know that in epithelial tissue covers the body of an animal and provides protection. Therefore statement in option 1 is true. The lining of alveoli, oesophagus, blood vessels and kidney tubules is made up of epithelial tissue. Hence statement in option 2 is also true. The cells of epithelium tissue are tightly packed and have very less intercellular spaces. Therefore statement in option 3 is false. Substances that enter and leave the body pass through any of the layers of epithelium. That’s why there is permeability between epithelial layers. Hence statement in option 4 is true.

1. It consists of single layer of cells forming the lining of the body cavities and ducts.

• columnar epithelium

• simple squamous epithelium

• cuboidal epithelium

• ciliated epithelium

2. ____________ is composed of elongated, slender and pillar shaped cells.

• cuboidal epithelium

• ciliated epithelium

• columnar epithelium

• squamous epithelium

3. This type of epithelium is seen in trachea, bronchioles of respiratory tract _______________

• glandular epithelium

• columnar epithelium

• ciliated epithelium

• squamous epithelium

The matrix of the bone is rich in ____________ salts and collagen fibres.

• Fluoride and calcium

• Calcium and phosphorus

• Calcium and potassium

• Phosphorus and potassium

Nerve cell does not contain

• Axon

• nerve ending

• tendons

• dendrites
