22 Chapters
Class 11 Biology is overall about living things and animal and plant kingdom. In addition, it gives a comprehensive knowledge about the living world. The book has 22 chapters each explaining different parts of organic life. Chapter 1 explains what is the living world and how it works. Chapter 2 describes the different biological classification of organic life. Chapter 3 teaches about the plant kingdom its various classification and characteristics. Chapter 4 is about the animal kingdom, its classification, and its characteristics. Chapter 5 is about the morphology of plants, which simply describe the different structures of plants. Chapter 6 is about the anatomy of flowering plants. Chapter 7 describes the structural organization of animals. Chapter 8 teaches about the cell, which is the fundamental unit of life. Chapter 9 discusses biomolecules that means the molecules that the living organisms produce. Chapter 10 explains the cell life cycle and cell division. Chapter 11 discusses the transport system in Plants. Chapter 12 is about the mineral nutrition requirement of plants. Chapter 13 explains the requirement and use of photosynthesis in higher plants. Chapter 14 teaches about respiration in Plants. Chapter 15 describes plant growth and development. Chapter 16 is about the digestion and absorption of plants. Chapter 17 defines the process of breathing and exchanges of gases. Chapter 18-22 describes circulation, excretory products, locomotion, neural control, and chemical coordination in plants.
Life is a unique characteristic of our planet Earth. It is not found to be existing on any other planet but in abundance on Earth. We are surrounded by life in different forms. Basically, we are living in "The Living World". So let us learn a bit about it in this section.
Classification is a very important aspect of Biology. It has greatly eased the study of various organisms and their evolution. All living organisms are widely classified into kingdoms based on their particular characteristics. In this chapter, we will learn about the biological classification and various kingdoms.

Flowers, leaves, stem, fruits. These are the parts of a plant we can see. Morphology is nothing but the study of the form, structure and types of these parts of a plant. Do you want to know more about these parts than just how they look? Do you want to know the characteristics and functions of each of these parts?
Flowers are not just pretty things to look at. Other than their beauty and fragrance they fulfil many more important functions. To start with, they are the reproductive organ of plants. They consist of many structures that help the plant survive, grow and reproduce. Let us take a look at the anatomy of flowering plants
Biomolecules are nothing but molecules present in living organisms. In fact, when scientists say they are looking for life on Mars, what they are actually looking for are biomolecules. Biomolecules come in a wide range of sizes and structures. Here we will learn about Biomolecules in further detail. Let us get started.
Are you aware that babies come from a single fetus and this fetus is made up of many single cells together? So, basically, we start our lives from a single cell. Isn't this amazing? So, how does a single cell goes on to form such large organisms?Let us study Cell Cycle and Cell Division in detail.
During lunchtime, Naina's mother served her bitter gourd. Looking at which Naina frowned and pushed the table across the table. Naina wondered how does transportation occur in humans and plants. Let us find out about transportation in animals and plants.
Just like you require certain minerals and other essential elements for proper growth and development, so do plants. Plants also have certain nutritional requirements for their growth and to enable themselves for the performance of their functions. Let us study mineral nutrition in detail, especially related to plants.
We all know the basics of photosynthesis. But that was in lower classes, now that we've grown up, its time we all about photosynthesis in higher plants. So, how does photosynthesis in higher plants differ? Let us upgrade our knowledge!
I'm sure all of us had this question when we were little. Why are plants considered living when they don't even move? Well, they may not move but they perform essential activities which are important for our survival. In this chapter, we are going to learn about respiration process in plants.
Growth is one of the fundamental characteristics of all living things. Even in Plants, the growth is visible but not measurable easily. Development in plants is actually a sum of two processes: growth and differentiation. Let us study further about plant growth and development.
Did you know that a human being on average eats about 500 kgs of food in a year! Can you imagine how intricate and highly functioning our digestive system is to process all this food? Let us learn many more interesting facts about digestion and absorption.
What will happen if you stop breathing? Or if your lungs stop working? What is the function of the lungs to begin with? Our respiratory system helps us in breathing and exchange of gases. But how does the system work to do so? Does the system include lungs? Let's dive in and explore everything
Did you know that your heart will probably beat three billion times in your lifetime? And that eight million blood cells died in your body a second ago? Let us learn more such fascinating facts and concepts about body fluids, such as blood and lymph and circulation.
Did you know that your body produces ammonia acid as a by-product? That's right. And ammonia is a toxic substance that must be flushed out. In fact, there are many nitrogenous wastes of varying toxicity that our body excretes. Let us take an in-depth look at the excretory systems of humans and plants.
Did you know it takes up to 12 muscles to smile? And did you know there are 27 bones in your hand alone? Locomotion and movement in humans is the sum effort of the muscles, joints and the skeletal system. Come, let us understand how vertebrates move around.
