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:
Points | Nervous tissue | Nervous system |
---|---|---|
Composition | Nervous tissue is made up of nerve cells called neurons. | Consists of group of nerve tissue that manages a number of nervous tissues. |
Parts | Neurons have three parts though they are varying in appearance as a cell body , dendrite(s),and an axon | CNS includes the brain and spinal cord . Cranial and spinal nerves form the peripheral nervous system(PNS). |
Function | Mediates messages to a specific body part at a particular point of time | Manages 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:
- Epithelial tissue
- Connective tissue
- Nervous tissue
- 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.

Structured/Application Questions
Question 1
Study the diagram given below and then answer the questions that follow:

- Identify the tissue and give a reason to support your answer.
- Name the parts labelled 1,2,3 and 4.
- Where is this tissue likely to be found in the plant?
- State the function of the parts labelled 1,2,3 and 4.
Answer
The given diagram is a longitudinal section of a phloem tissue of a plant as the cells exhibit cellular contents.
The following parts are labelled:
- 1 → Sieve cell
- 2 → Phloem parenchyma cell
- 3 → Companion cell
- 4 → Sieve plate
This tissue is likely to be found in the stem and leaves as it is the tissue that conducts food, the manufactured food in the leaves needs to be transported to other parts of the plant.
The functions of the labelled parts are as follows-
- 1 → Sieve cell — Assists in transporting food from leaves to storage structures and other plant parts.
- 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.
Question 2
Study the diagram given below and then answer the questions that follow:

- Identify the cell.
- Name the parts labeled 1,2,3,4,5, and 6.
- Where is this cell likely to be found in the human body and what is its function.
Answer
- The cell is the neuron or the nerve cell.
- The labelled parts are:
- 1 → Dendrite
- 2 → Axon
- 3 → Nucleus
- 4 → Perikaryon/Cyton
- 5 → Neurolemma
- 6 → Axon endings
- In human body, the nerve cell is found in the nervous system.
