Free Tissues 02 Practice Test - 9th Grade 

Question 1

Group of one or more type of similar cells with a similar origin and specialised to perform specific function(s) are called ______.

A. organelles
B. tissues
C. organs
D. organ system

SOLUTION

Solution : B

A group of cells having a common origin and co-operating with one another to perform a similar function or a set of similar functions, is described as a tissue. Some examples of tissues are muscular tissues, nervous tissues, meristematic tissues, etc.

Question 2

Which among the following are characteristics of meristematic tissues?

A. Lack vacuole
B. Thin cellulosic cell wall
C. Prominent nuclei 
D. Have intercellular spaces

SOLUTION

Solution : A, B, and C

Meristematic tissue is a simple tissue composed of a group of cells which can divide and produce new cells. These are small immature cells. They do not contain intercellular spaces. Their walls are thin, elastic and are made up of cellulose. They are living cells with prominent nucleus and abundant cytoplasm, and lack vacuole.

Question 3

Which tissue is responsible for the increase in the girth of the stem?

A.

Apical meristem

B.

Cambium

C.

Intercalary meristem

D.

Xylem

SOLUTION

Solution : B

Cambium (lateral meristem) is situated below the bark and is responsible for the increase in the girth of the stem or root.

 

Question 4

Which of the following is responsible for the transportation of food in plants?

A. Xylem
B. Phloem
C. Cambium
D. Stomata

SOLUTION

Solution : B

  • Xylem and phloem are the complex permanent tissues in plants.Phloem is responsible for the movement of food manufactured in leaves to other parts of the plant.
  • Xylem is involved in the conduction of minerals and water from roots to the other parts of the plants.
  • Cambium (lateral meristem) is situated below the bark and is responsible for the increase in the girth of the stem or root.
  • Stomata allow gaseous exchange during photosynthesis and transpiration.

Question 5

Axons bundled together form a muscle.

A.

True

B.

False

SOLUTION

Solution : B

Neurons are the specialised cells of the nervous system. Each neuron has a cell body, a long axon and axon terminal. The axons bundle together to form a nerve fibre. Whereas, the muscles are made up of muscular tissue.

Question 6

Which of the following is composed of nervous tissue?

A. Brain
B. Large instestine
C. Stomach
D. Small intestine

SOLUTION

Solution : A

The cells of nervous tissue are specialised for receiving stimuli and transmitting messages. Brain, spinal cord and nerves are composed of nervous tissue. The cells of this tissue are called nerve cells or neurons.

Question 7

Which of the following pair forms the vascular bundle?

A. Parenchyma and sclerenchyma
B. Xylem and parenchyma
C. Xylem and phloem
D. Phloem and collenchyma

SOLUTION

Solution : C

Xylem and phloem together form the vascular bundle. They are called conducting tissues. Vascular or conductive tissue is a distinctive feature of the complex plants. Parenchyma, collenchyma and sclerenchyma on the other hand form the simple permanent tissue (ground tissues).

Question 8

Which of the following statements are true for cartilage?

A. It is a type of connective tissue
B. As hard as bone
C. Present at the tip of the nose
D. Connects muscles to bones

SOLUTION

Solution : A and C

Cartilage is a type of connective tissue. It is a soft skeletal tissue, not rigid like bone. The solid matrix of cartilage consists of water, proteins, carbohydrates and chondrin (flexible material). It is present in the joints of bones, tip of ribs, tip of nose, external ears and in trachea. The entire skeleton of shark is made of cartilage.

Question 9

I am a complex sugar found in plants responsible for hardening of sclerenchyma. Who am I?

A. Glucose
B. Cellulose
C. Lignin
D. Suberin

SOLUTION

Solution : C

Lignin is present in stems, around vascular bundles, in the veins of leaves and in the hard covering of seeds and nuts. It provides strength to the plant parts. It is largely a supportive structure and is part of the secondary thickening of tall plants. It is a major constituent of woody material. The cells of sclerenchyma are dead, long and narrow because their walls are thickened due to lignin. It acts as a cement and hardens them.  Often these walls are so thick that there is no internal space in between the cells.

Question 10

Identify the meristematic tissues A, B and C given in the image.

A. A: Apical meristem
B: Lateral meristem
C: Intercalary meristem
B. A: Intercalary meristem
B: Lateral meristem
C: Apical meristem
C. A: Apical meristem
B: Intercalary meristem
C: Lateral meristem
D. A: Lateral meristem
B: Apical meristem
C: Intercalary meristem

SOLUTION

Solution : C

Apical meristem is present at the growing tips of stems and roots and increases the length of the stem and the root. Lateral meristem is responsible for the increase of girth (width) of the stem or root. Intercalary meristem is present at the base of the leaves or internodes (between two nodes) on twigs.
