Find well-explained and accurate solutions to all the textbook exercises to strengthen your understanding of Chapter 6.
Q1. Draw illustrations to bring out the anatomical differences between
(i) Monocot root and Dicot root
Answer:
Monocot root
Dicot root-
(b) Monocot stem and Dicot stem
Answer:
Monocot Stem:
- Vascular Bundles: Scattered and isolated in the stem.
- Cambium: None; no vascular cambium exists.
- Cortex and Pith: No differentiation between cortex and pith.
Dicot Stem:
- Vascular Bundles: Formed in a ring.
- Cambium: Exists; vascular cambium provides for secondary growth.
- Cortex and Pith: Separation between cortex (outer) and pith (inner).
By confirming these features under the microscope, you can determine if the stem is monocotyledonous or dicotyledonous.
Q3. The transverse section of a plant material shows the following anatomical features -
(i) The vascular bundles are conjoint, scattered and surrounded by a sclerenchymatous bundle sheath.
What will you identify it as?
(ii) Phloem parenchyma is absent.
Answer:
(a) Vascular bundles are isolated and embedded in sclerenchyma.
(b) There is no phloem parenchyma.
Conclusion:
These characteristics are characteristic of a monocot stem.
Q4. What is stomatal apparatus? Explain the structure of stomata with a labelled diagram.
Answer:
Stomatal apparatus includes:
- Stomata: Tiny openings on leaves that allow gas exchange (uptake of CO₂, outflow of O₂).
- Guard Cells: Bean-shaped (in dicots) or dumbbell-shaped (in monocots); open or shut stomata.
- Subsidiary Cells: Enclose guard cells and offer structural support.
Answer:
The three basic tissue systems in the flowering plants include epidermal tissue system, ground tissue system and vascular tissue system.
1. Epidermal Tissue System
Tissues: Epidermis, Cuticle, Stomata, Trichomes
2. Ground Tissue System
Tissues: Parenchyma, Collenchyma, Sclerenchyma
3. Vascular Tissue System
Tissues: Xylem (for water transport), Phloem (for food transport)
Q 6. How is the study of plant anatomy useful to us?
Answer:
The analysis of plant anatomy proves to be useful in the following ways:
- Identification of Species: Aids in differentiating among plant species.
- Determination of Age: Suggests the age of trees in terms of annual rings of growth.
- Adaptation Hints: Provides insights into the adaptation of plants in different environments.
- Commercial Usefulness: Proves useful in commercial industries that involve wood, fibres, and other plant products.
Q 7. Describe the internal structure of a dorsiventral leaf with the help of labelled diagrams.
Answer:
The internal structure of a dorsiventral leaf includes:
Upper Epidermis: A protective layer often covered with a cuticle to reduce water loss.
Mesophyll:
- Palisade Parenchyma (upper layer): Contains chloroplasts for photosynthesis.
- Spongy Parenchyma (lower layer): Loosely arranged for gas exchange through intercellular spaces.
Lower Epidermis: Contains stomata for transpiration and gas exchange.
Vascular Bundles: Composed of xylem (for water transport) and phloem (for food transport).
NCERT Solutions for Class 11: Subject-wise
Important Question from Chapter 6 Anatomy of Flowering Plants
Question 1: Passage cells are thin-walled cells found in
Options
1- Endodermis of roots facilitates the rapid transport of water from the cortex to the pericycle
2- Phloem elements that serve as entry points for substances for transport to other plant parts
3- Testa of seeds to enable the emergence of the growing embryonic axis during seed germination
4- Central region of style through which the pollen tube grows towards the ovary
Answer:
In roots, the innermost layer of the cortex is known as the endodermis, which is an important regulating layer in the movement of water and nutrients. Some endodermal cells, opposite the xylem patches, are thin-walled and are termed passage cells or transfusion cells. These passage cells can perform direct transfers of water and dissolved salts from the cortex to the xylem, thus allowing direct transport to the vascular system and thence to the pericycle, which then allows for distribution throughout the plant.
Hence, the correct answer is option (1), endodermis of roots facilitating rapid transport of water from cortex to pericycle.
Approach to Solve Questions of Class 11 Chapter 6
To solve questions effectively from this chapter, students can follow the steps provided below:
- Understand the organization, types, and functions of meristematic and permanent tissue, as well as complex tissue (xylem, phloem).
- Practice labeled diagrams of transverse sections of monocot and dicot roots, stems, and leaves, which will come in handy for theory questions and diagram questions.
- Compare monocot and dicot structure charts based on vascular bundle pattern, ground tissue, pith, and the presence of cambium.
- Understand dicot stem secondary growth in detail, annual ring formation, and sapwood and heartwood, with a clear explanation.
- Solve previous-year questions to get familiar with the question pattern and gain confidence to score better marks in the exam.

3. What are the types of tissues in flowering plants according to NCERT Class 11 Biology?
Types of Tissues in Flowering Plants (NCERT Class 11 Biology)
Meristematic Tissues – helps in plant development by dividing continuously.
Permanent Tissues – Do not divide, give support and function.
Simple Permanent Tissues: Parenchyma, Collenchyma, Sclerenchyma.
Complex Permanent Tissues: Xylem and Phloem.
4. What is the difference between monocot and dicot stem anatomy?
Difference Between Monocot and Dicot Stem Anatomy
Monocot Stem:
- Vascular bundles are scattered.
- No cambium, no secondary growth.
Dicot Stem: - Vascular bundles are in a ring.
- Has cambium, undergoes secondary growth.
5. What are the different types of vascular bundles explained in NCERT Class 11 Biology?
Types of Vascular Bundles (NCERT Class 11 Biology)
- Radial – Xylem and phloem in different bundles (roots).
- Conjoint – Xylem and phloem in the same bundle (stems & leaves).
- Collateral – Xylem within, phloem without (stems).
- Bicollateral – Phloem on each side of xylem.
- Closed – No cambium, no secondary growth.
- Open – Has cambium, can grow secondarily.
6. What is secondary growth in plants, and why is it important?
- Secondary growth adds thickness to stems and roots.
- It occurs because of vascular cambium and cork cambium.
- Important for strength, support, and conduction of water.
7. What are simple and complex permanent tissues in flowering plants?
Simple and Complex Permanent Tissues in Flowering Plants
- Simple Permanent Tissues: Parenchyma, Collenchyma, Sclerenchyma.
- Complex Permanent Tissues: Xylem and Phloem (transport tissues).
8. How is the anatomy of the root different from the anatomy of the stem?
Difference Between Root and Stem Anatomy
Root Anatomy:
- Xylem in a star shape (dicot) or ring (monocot).
- Contains root hairs for absorption.
Stem Anatomy:
- Vascular bundles in a ring (dicot) or scattered (monocot).
- Supports leaves and conducts nutrients.
9. What is the function of the cambium in plant growth?
Role of Cambium in the Growth of the Plant
- The vascular cambium forms new phloem and xylem, adding thickness.
- Cork cambium gives rise to the cork for defense.
- A requisite for secondary growth.
10. How do you differentiate between open and closed vascular bundles?
Open Vascular Bundles: Have cambium, permit secondary growth (dicots).
Closed Vascular Bundles: No cambium, no secondary growth (monocots).
