Significance of Biology Class 11 NCERT PDF

Biology is a branch of science that deals with living organisms and life. Thus, it is known as life science or science of life. NCERT books for class 11 biology serves as the best source of fundamental concepts of biology. Students can gather information to a great extent by reading this book.

Moreover, 11th NCERT biology book also helps students to explore their knowledge about their daily life as well. Both plant and animal kingdom, which is equally important for the board and NEET exam are discussed here.

So, students can download NCERT biology class 11 PDF anytime to increase their grip on the subject for both exams efficiently.

Chapter Wise Overview of Class 11 Biology NCERT PDF Book

The entire biology syllabus of CBSE board is divided into four units where each unit comprises of several chapters. Let’s start with unit 1, that includes four sections.

Unit 1: Diversity in the Living World

Chapter 1: The Living World

The first chapter of NCERT books for class 11 biology begins with a wide range of living organisms present in this ecosystem. While explaining the definition of living things, this chapter also represents the ecological clash and cooperation among these members. Students can learn about various physiological systems that help living beings to sustain and carry forward their species. 

This chapter further encapsulates the prevailing diversity that is prominently visible in every part of the world, irrespective of weather and environment. Also, the taxonomic categories and taxonomical aids of these living organisms are explicitly described here.

Chapter 2: Biological Classification

Since the beginning of civilisation, humans tried to categorise the entire known living population for the sake of their uses like shelter, clothing, and food. Aristotle first attempted to classify them scientifically. He divided the plant kingdom into three classes – herbs, shrubs, and trees. Moreover, he also classified the animal kingdom into two sections – animals with red blood and the other which did not have.

This second chapter of 11th NCERT biology PDF deals with this scientific classification process and also explains five different classes like Monera, Protista, Fungi, Plantae, and Animalia, and also about Viroid, Viruses, and Lichens. 

Chapter 3: Plant Kingdom

From the previous topic, students have learned about the five classifications of the plant kingdom. In this chapter of class 11 biology book PDF, they can gather knowledge about Kingdom Plantae or plant kingdom and its further classifications. 

The entire plant kingdom is classified into five sections – Algae, Bryophytes, Pteridophytes, Gymnosperms, and Angiosperms. This chapter explains the typical characteristics of each of these plant classes and helps to understand the process of classification. Furthermore, students can also learn about different life cycles of plants and also their alteration of generation. Thus, students can achieve a firm base about plant kingdom, its taxonomy.

Chapter 4: Animal Kingdom

The fourth chapter of NCERT class 11 biology book PDF deals with the Kingdom Animalia and a systemic classification process where all known members can be assigned to a class scientifically. The first half of this chapter explains what the basis of this classification system is.  The taxonomical factors include organisation levels, symmetry, triploblastic and diploblastic organisations, coelom, segmentation, and notochord.

Furthermore, the seconds part of this topic is about the classification of this kingdom on the basis of common fundamental physical features. These classifications are Phylum – Porifera, Coelenterata, Ctenophora, Platyhelminthes, Aschelminthes, Annelida, Arthropoda, Mollusca, Echinodermata, Hemichordata, and Chordata.

Unit 2: Structural Organisation in Plants and Animals

From here, the second unit of the syllabus starts. This unit includes three consecutive chapters from five to seven.

Chapter 5: Morphology of Flowering Plants

Morphology suggests the study of the external structure of various organisms. This fifth chapter of NCERT biology class 11 new edition PDF presents the structure of higher plants’ external parts, their importance, and working process as well. Previously, students have learnt the classification of plants based on their morphological and other distinct characteristics.

Here, all these morphological characteristics are described in a well-presented manner. In this chapter, students can study the root, stem, leaf, inflorescence, flower, fruit, and seed. Moreover, it also contains a description of common flowering plants and explains the typical characteristics of some vital plant families.

Chapter 6: Anatomy of Flowering Plant

Structural variations and similarities can be spotted easily by observing the living organism. However, anatomy is the study of internal structures and their functions. This sixth chapter of biology 11th NCERT PDF biology 11th NCERT PDF book provides a detailed description of functional organisation and internal structure of higher plants. 

In other words, this chapter teaches about the different types of tissues found in plant bodies, and tissue system based on the location. Anatomy of monocotyledonous and dicotyledonous plants are also elaborately described in this chapter. Moreover, students can get to know about two different growth of plants- primary and secondary growth.


Chapter 7: Structural Organisation in Animal

In this seventh chapter of class 11 biology NCERT book PDF, students can gather knowledge about multicellular and unicellular organisms of the animal kingdom. Unicellular organisms perform all of their life processes like respiration, reproduction, digestion, etc. with the help of a single cell. At the same time, multicellular organisms use various organs developed by different cells to perform different functions.

So, this chapter is all about various animal tissues, cells, organs and their systems, functions, etc. As an example, students can see the morphological and anatomical structure of earthworm, cockroach, and frog. All these three animals represent vertebrates and invertebrates. So, students can have an idea about animal structure by learning about these animals.

Unit 3: Cell: Structure and Function

Now, this CBSE class 11 biology book has come to another new unit. This unit has three chapters in it, and they are all about the function and structure of the cell.

Chapter 8: The Unit of Life

This chapter of biology 11 NCERT PDF starts with explaining that cell is the fundamental unit of life. All living organisms are made of cell- it could be a single-celled or multiple-celled.

Chapter 9: Biomolecules

All living organisms in this biosphere are composed of different chemicals that are known as compounds and elements. The ninth chapter of NCERT 11 biology book PDF explains the process of analysing chemical compositions in living organisms. Biomolecules help to identify these compounds by synthesising, and these are called metabolites. This topic also provides elaborated knowledge about different metabolites.

Moving forward, students get to know about various biomolecules, proteins, polysaccharides, nucleic acid, etc. A detailed idea about protein structure, characters of bonds that link monomers in polymers, metabolism concept, etc. can also be derived from this topic. Importance of metabolism, various enzymes and their functions are also available here.

Chapter 10: Cell Cycle and Cell Division

This is the last chapter of this unit, where students learn about every aspect of the cell. This topic of NCERT books PDF class 11 biology speaks about a biological phenomenon that every living being starts with a single cell, and they gradually grow to be a multicellular organism. It describes how this process works and what is a cell cycle. 

Students can also study different phases of cell cycle like interphase, M phase, G1, S, and G2 phase, prophase, metaphase, anaphase, etc. In the other part of this chapter, students can prepare cell divisions and its classifications. It explains two major process mitosis and meiosis and their significance, working process.

Unit 4: Plant Physiology

This is the start of unit four, that includes five chapters. This unit is all about plant physiology and its various aspects.
