Test: The Tissue System (NCERT) - Question 1

Given figures (P and Q) represent the stomatal apparatus of dicot and monocot leaves respectively. Select the option which correctly labels A, B and C.


Detailed Solution for Test: The Tissue System (NCERT) - Question 1

A typical stoma is microscopic and usually consists of two kidney-shaped guard cells surrounding a pore. The guard cells are usually much smaller in size as compared to other epidermal cells. In some species the guard cells are surrounded by subsidiary cells or accessory cells which differ morphologically from the other epidermal cells. Guard cells possess few small chloroplasts, they are bean or kidney shaped in most dicots and dumb-bell shaped in most monocots.

Test: The Tissue System (NCERT) - Question 2

Select the mismatched pair.

Detailed Solution for Test: The Tissue System (NCERT) - Question 2

Trichomes are unicellular or multicellular, branched or unbranched outgrowths which are strictly epidermal in origin. Being the outermost layer trichome is protective in nature. With the help of cuticle it checks the rate of water loss from aerial parts. Trichomes present on the surface of some seeds and fruits help in their dispersal.

Test: The Tissue System (NCERT) - Question 3

Which of the following tissue systems constitutes bulk of the plant body?

Detailed Solution for Test: The Tissue System (NCERT) - Question 3

Ground tissue system includes all the tissues of plant body except epidermal tissue system and vascular tissues. It forms the bulk of body and consists of mainly parenchymatous, collenchymatous, sclerenchymatous, glandular and laticiferous tissues.

Test: The Tissue System (NCERT) - Question 4

Lateral meristems are cylindrical meristems and they occur in the mature regions of root and shoot of many plants. Which of the following are examples of lateral meristems?

a. Cork-cambium
b. Intercalary meristem
c. Fascicular vascular cambium
d. Apical meristem

Detailed Solution for Test: The Tissue System (NCERT) - Question 4

This is the correct option. Cork-cambium and fascicular vascular cambium are examples of lateral meristems. Secondary tissues are produced by them.

Test: The Tissue System (NCERT) - Question 5

Identify the type of vascular bundle as shown in the figure and select the incorrect statement regarding this.

Detailed Solution for Test: The Tissue System (NCERT) - Question 5

The given figure represents radial vascular bundles. Here xylem and phloem occur in the form of separate bundles called xylem bundles and phloem bundles. The two types of bundles usually alternate with each other. They occur on different radii. Radial bundles are characteristic of monocot and dicot roots. 

Test: The Tissue System (NCERT) - Question 6

Why are monocotyledonous vascular bundles referred to as closed?

Detailed Solution for Test: The Tissue System (NCERT) - Question 6

Solution: 
They do not form secondary tissues. Explanation: Monocotyledonous vascular bundles are referred to as closed because they do not have cambium and, as a result, cannot form secondary tissues.

Test: The Tissue System (NCERT) - Question 7

What do open vascular bundles possess that allows them to form secondary xylem and phloem tissues?

Detailed Solution for Test: The Tissue System (NCERT) - Question 7

Open vascular bundles possess cambium between phloem and xylem, which enables them to form secondary xylem and phloem tissues.

Test: The Tissue System (NCERT) - Question 8
What is the role of the cuticle in plants?
Detailed Solution for Test: The Tissue System (NCERT) - Question 8
The cuticle is a waxy layer that covers the epidermis of plants. Its primary function is to prevent water loss, especially in aerial parts of the plant like leaves. It acts as a barrier to water and other substances, thus helping in water conservation.
Test: The Tissue System (NCERT) - Question 9

What distinguishes open vascular bundles from closed vascular bundles?

Detailed Solution for Test: The Tissue System (NCERT) - Question 9

Open vascular bundles are distinguished by the presence of cambium, a meristematic tissue that allows for secondary growth by producing additional xylem and phloem. This feature is characteristic of dicotyledonous plants. In contrast, closed vascular bundles, typically found in monocotyledons, lack cambium and therefore do not undergo secondary growth.

Test: The Tissue System (NCERT) - Question 10

Which of the following structures is responsible for gas exchange in plants?

Detailed Solution for Test: The Tissue System (NCERT) - Question 10

Stomata are small openings found on the underside of leaves that are responsible for gas exchange. They allow carbon dioxide to enter the leaf for photosynthesis and oxygen to exit as a byproduct, while also playing a role in water regulation.
