Short Answer Type

Question 1

Name any one body part where ciliated epithelium is found in humans? What is its function?

Answer

We find ciliated epithelium tissue in the lining of the trachea.

Ciliated epithelium is a thin tissue that has hair-like structures on it. These hairs called cilia move back and forth to help move particles out of our body.

Question 2

What is the difference between the nervous tissue and the nervous system?

Answer

The nervous tissues work together and form the nervous system,which is essential for the functioning of the body.

The differences between the nervous tissue and the nervous system are:

PointsNervous tissueNervous system
CompositionNervous tissue is made up of nerve cells called neurons.Consists of group of nerve tissue that manages a number of nervous tissues.
PartsNeurons have three parts though they are varying in appearance as a cell body , dendrite(s),and an axonCNS includes the brain and spinal cord . Cranial and spinal nerves form the peripheral nervous system(PNS).
FunctionMediates messages to a specific body part at a particular point of timeManages tissues that passes messages to the entire body.

Question 3

List the tissues found in the human heart?

Answer

The tissues found in the human heart are:

  1. Epithelial tissue
  2. Connective tissue
  3. Nervous tissue
  4. Muscular tissue

Question 4

Can you consider a cluster of eggs as a tissue? Why?

Answer

No, we cannot consider a cluster of eggs as a tissue. A tissue is a group of cells having a common origin and performing a common function. A cluster of eggs is not a tissue since each egg has individual function and they don't function as a group.

Question 5

    • 2 → Phloem parenchyma cell — Stores fat, starch and other organic food material.
    • 3 → Companion cell — Facilitates the functioning of the cells of sieve tube.
    • 4 → Sieve plate — Dissolved organic solutes and water permeates through these structures as it contains perforations.
