Solution C.1

Ciliated columnar epithelium is found in the lining of trachea. This epithelium has thread-like projections called cilia at their free ends. The cilia constantly keep lashing and move the materials which enter this organ.

Question C.2

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

Solution C.2

Nervous tissue or neurons are specialized group of cells. This tissue is concerned with perception and responses of animals.

The nervous tissue constitutes the nervous system, which is an organ system. It controls and coordinates all the systems of the body.

Question C.3

List the tissues found in the human heart.

Solution C.3

(1) Muscular tissue (Cardiac muscles)

(2) Epithelial tissue (Lining of blood vessels of the heart)

(3) Connective tissue (Fluid connective tissue in the form of red blood corpuscles)

Question C.4

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

Solution C.4

A tissue is a group of similar cells from the same origin that together carry out a specific function. An egg is a zygote or a cell but a cluster of eggs cannot be considered as a tissue as it does not form an organ like a tissue. Instead it gives rise to a new individual organism if gets fertilised. 

Question C.5

Name the three kinds of muscles found in the human body. In each case, name one region in the body where they are found.

Solution C.5

(1) Striated muscles: Provide the force for locomotion and all voluntary movements of the body. These muscles are found in the limbs.

(2) Unstriated muscles: Provide movements for the passage of food in the intestines. These muscles are found in iris of the eye, lining of blood vessels, urinary bladder, etc.

(3) Cardiac muscles: Provide rhythmic contraction and relaxation movements. These muscles are found only in the heart.

(a) cell and tissue?

(b) organ and organism?

(c) organ and organelle?

(d) organ and organ system?

Solution D.1

(a) Cell and tissue

(c) Where is this tissue likely to be found in the plant?

(d) State the function of the parts labelled 1, 2, 3 and 4.

(d)

1 → Sieve cells: Help in the transport of food from leaves to storage organs and other parts of the plant.

2 → Phloem parenchyma cells: Storage of starch, fat and other organic food material.

3 → Companion cells: Help in the functioning of the sieve tube cells.

4 → Sieve plate: Perforations in the sieve plates allow water and dissolved organic solutes to flow along the sieve tube.
