Questions + Answers key
Take MCQ Science Test

1.
Identify the type of tissue in the following:
Skin, bark of tree, bone, lining of kidney tubule, vascular bundle
2.
What are permanent tissues?
3.
How many types of meristems are present in plants, on the basis of position?
4.
List any four salient features of meristematic tissue.
5.
What are characteristic structural features of meristematic cells?
6.
What are structural and functional difference between plants and animals?
7.
What is the specific function of the cardiac muscle?
8.
What is the utility of tissues in multi-cellular organisms?
9.
What is a tissue?
10.
Give the differences between tendon and ligament.
11.
What is the difference between
(i) meristematic cells and permanent cells?
(ii) parenchyma and collenchyma?
12.
Permanent tissues of plants are derived from ................ tissue.
13.
The two main types of tissues of plant are ............. and permanent.
14.
A group of cells similar in structure and function is called as .................
15.
Chlorenchyma is a type of ............... which contains chlorophyll and performs photosynthesis.
16.
The growth of plants occurs only in certain regions because the dividing tissue called .............. tissue located only at that regions.
17.
How many guard cells enclose a stoma?
One
Two
Three
Four
1.
(i) Skin - Striated squamous epithelium
(ii) Bark of tree - Cork (protective tissue)
(iii) Bone - Connective tissue
(iv) Lining of kidney tubule - Cuboidal epithelium
(v) Vascular bundle - Conducting tissue (xylem and phloem).
2.
The cells of meristematic tissue lose the ability to divide and get differentiated into specialised cells. These differentiated cells from different types of tissues which are known as permanent tissues. Some examples of permanent tissues are parenchyma, sclerenchyma, etc.
3.
On the basis of location of meristem, it is classified into three types:
(i) Apical meristem is present at the tip of stem, root and their branches.
(ii) Intercalary meristem is found at the leaf base, above the nodes (i.e., at the base of internodes as in grasses) or below the nodes (i.e., at the upper most region of internode as in mint.)
(iii) Lateral meristem
Vascular cambium and cork cambium are the examples of lateral meristem. Vascular cambium is found in vascular bundles while cork cambium is found underneath the bark of trees. Both of these cause increase in girth of plants.
4.
(i) This tissue consists of actively dividing cells.
(ii) This tissue is present in growing regions of plants.
(iii) In this tissue, cells are packed closely without intercellular spaces.
(iv) Cells of this tissue have thin cell walls, dense cytoplasm and prominent nuclei.
5.
Meristematic cells have:
(i) Thin cell walls.
(ii) Abundant or dense cytoplasm and single large nucleus.
(iii) Spherical, oval, polygonal or rectangular shape.
(iv) No intercellular spaces between them.
(v) Either no vacuoles at all or a few vacuoles.
6.
| S.No. | Plants | Animals |
| 1. | Plants are stationary, they do not move. They do not need much energy. | 1. Animals move in search of food, mate and shelter. They need more energy as compared to plants. |
| 2. | Their most of the tissues are dead and supportive which provide structural strength. | 2. Most of the tissues they contain are living and contain protoplasm. |
| 3. | In plants, growth is limited to certain regions. | 3. In animals, growth is uniform and not limited to certain regions. |
7.
The specific function of cardiac muscle is to contract and relax rhythmically throughout life.
8.
It helps in growth, organisation of different organs and performing different functions.
9.
Tissue is a group of cells that are similar in structure and are organised together to perform a specific task.
10.
The differences between tendon and ligament are as follows:
| Tendon | Ligament |
|---|---|
| It is strong and non-flexible in nature. | It is elastic and flexible in nature. |
| It joins muscles to bones. | It joins bones to bones. |
| It is formed of white fibrous connective tissue. | It is formed of yellow fibrous connective tissue. |
11.
(i) Difference between Meristematic cells and Permanent cells
| Meristematic Cells | Permanent Cells |
| 1. They have dense cytoplasm and a large centrally placed nucleus. | 1. They have a large central vacuole, and normal nucleus. |
| 2. These cells are capable of dividing to produce new cells. | 2. They attain permanent shape and are not capable of producing new cells. |
(ii) Difference between Parenchyma and Collenchyma
| Parenchyma | Collenchyma |
|---|---|
| 1. It is living and mainly storage tissue. | 1. It is living and mainly provides tensile strength to stem and leaf stalk. |
| 2. Parenchymatous cells have large intercellular spaces. Their walls do not have thickening at the corners. | 2. Collenchymatous cells have very little intercellular spaces. They have thickening at the corners of cell walls. |
