Test your comprehensive knowledge of the structural organisation of plants and animals, including morphology, anatomy, and physiological processes, based on NCERT Biology.

Test Your Knowledge

Showing questions 1 - 20 of 128

1. Which of the following was the primary method for describing diverse forms of life on Earth before experimental biology was established?

Molecular analysis
Genetic sequencing
Observation through naked eyes or magnifying lenses
Physiological experiments

Before experimental biology or physiology was established, naturalists described biology mainly through observation using naked eyes or later magnifying lenses and microscopes, focusing on gross structural features and perceivable living phenomena.

2. How did the detailed description of life forms and their structure contribute to later day reductionist biology?

It became obsolete with the advent of experimental biology.
It solely provided a historical record without practical application.
It was primarily a source of boredom for students.
It was utilized in framing research questions in physiology or evolutionary biology.

The detailed description of life forms, while initially seeming tedious, was crucial for later day reductionist biology, where it became meaningful and helpful in framing research questions in physiology or evolutionary biology.

3. Katherine Esau's early publications reported the spread of curly top virus through which plant tissue?

Xylem tissue
Parenchyma tissue
Phloem tissue
Epidermal tissue

Katherine Esau reported in her early publications that the curly top virus spreads through a plant via the food-conducting or **phloem tissue**.

4. Which of Katherine Esau's works was referred to as 'Webster’s of plant biology' due to its encyclopedic nature?

Plant Anatomy (1954)
The Anatomy of Seed Plants (1960)
Her doctoral dissertation (1931)
Her early publications on curly top virus

The Anatomy of Seed Plants by Katherine Esau, published in 1960, was referred to as Webster’s of plant biology because it is **encyclopedic**.

5. Which of the following awards did Katherine Esau receive from President George Bush in 1989?

Nobel Prize in Physiology or Medicine
Pulitzer Prize
National Medal of Science
National Academy of Sciences membership

In addition to being elected to the National Academy of Sciences in 1957, Katherine Esau received the **National Medal of Science** from President George Bush in 1989.

6. Despite their large diversity in external structure, all angiosperms are characterized by the presence of which of the following structures?

Bulbs, corms, and tubers
Roots, stems, leaves, flowers, and fruits
Rhizoids, thalli, and sporophytes
Spores, cones, and scales

Even though angiosperms show a large diversity in external structure or morphology, they are all characterized by the presence of **roots, stems, leaves, flowers, and fruits**.

7. In flowering plants, the root system constitutes which part of the plant?

The portion above the ground
The entire plant body
The underground part
Only the reproductive organs

The **underground part** of the flowering plant is the root system, while the portion above the ground forms the shoot system.

8. In the majority of dicotyledonous plants, the primary root develops from the direct elongation of which embryonic part?

Plumule
Cotyledon
Radicle
Scutellum

In the majority of the dicotyledonous plants, the direct elongation of the **radicle** leads to the formation of the primary root.

9. Which type of root system is characteristic of monocotyledonous plants, where the primary root is short-lived and replaced by roots originating from the base of the stem?

Tap root system
Adventitious root system
Fibrous root system
Prop root system

In monocotyledonous plants, the primary root is short-lived and is replaced by a large number of roots. These roots originate from the base of the stem and constitute the **fibrous root system**, as seen in the wheat plant.

10. Which of the following plants are examples of those with adventitious roots?

Mustard and Pea
Wheat and Maize
Grass, Monstera, and Banyan tree
China rose and Brinjal

In some plants, like **grass, Monstera and the banyan tree**, roots arise from parts of the plant other than the radicle and are called adventitious roots.

11. All of the following are main functions of the root system EXCEPT:

Absorption of water and minerals from the soil
Providing proper anchorage to the plant parts
Synthesis of plant growth regulators
Production of flowers and fruits

The main functions of the root system are absorption of water/minerals, anchorage, storing reserve food, and synthesis of plant growth regulators. **Production of flowers and fruits** is a function of the shoot system.

12. Which region of the root is responsible for the growth of the root in length?

Root cap
Region of meristematic activity
Region of elongation
Region of maturation

The cells proximal to the region of meristematic activity undergo rapid elongation and enlargement and are responsible for the growth of the root in length. This region is called the **region of elongation**.

13. Root hairs, which absorb water and minerals from the soil, are formed by the epidermal cells in which region of the root?

Region of meristematic activity
Root cap
Region of elongation
Region of maturation

From the **region of maturation**, some of the epidermal cells form very fine and delicate, thread-like structures called root hairs. These root hairs absorb water and minerals from the soil.

14. Which part of the embryo does the stem develop from?

Radicle
Cotyledon
Plumule
Hypocotyl

The stem develops from the **plumule** of the embryo of a germinating seed.

15. What are the regions on the stem where leaves are born called?

Internodes
Axillary buds
Nodes
Stipules

The region of the stem where leaves are born are called **nodes**, while internodes are the portions between two nodes.

16. Which of the following is NOT a primary function of the stem?

Spreading out branches bearing leaves, flowers and fruits
Conduction of water, minerals and photosynthates
Storage of reserve food material
Absorption of water and minerals from the soil

The main functions of the stem include spreading out branches, conduction, storage, support, protection, and vegetative propagation. **Absorption of water and minerals from the soil** is primarily a function of the root system.

17. Leaves originate from which meristematic tissue?

Root apical meristem
Lateral meristem
Shoot apical meristem
Intercalary meristem

Leaves originate from **shoot apical meristems** and are arranged in an acropetal order.

18. What are the three main parts of a typical leaf?

Root, Stem, Flower
Epidermis, Cortex, Vascular Bundle
Leaf base, Petiole, Lamina
Midrib, Vein, Veinlet

A typical leaf consists of three main parts: **leaf base, petiole and lamina**.

19. In some leguminous plants, the leaf base may become swollen. What is this swollen leaf base called?

Stipule
Sheath
Pulvinus
Petiole

In some leguminous plants, the leaf base may become swollen, which is called the **pulvinus**.

20. What is the primary function of the petiole in a leaf?

To perform photosynthesis
To provide rigidity to the leaf blade
To absorb water and minerals
To help hold the blade to light and allow fluttering for cooling

The petiole helps hold the blade to light. Long thin flexible petioles allow leaf blades to flutter in wind, thereby cooling the leaf and bringing fresh air to the leaf surface.
