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.

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
