NCERT Class 11 Biology Book
The world of plants and animals is fascinating. Since you have opted for Biology in Class 11, you are probably quite fascinated by the various kinds of life on Earth. To understand the concepts properly, you can go through the tutorials in Aakash Live and iTutor app. While curiosity can give you a good start, you will need a well-crafted plan to tackle such a huge syllabus.
You can also study and prepare for Board Exams with our specialized Board Courses for Classes 10th and 12th. The first chapter will introduce the students with the diverse world of living organisms and living processes. It will teach you the three domains of life, the need for a standardized taxonomy and systematics for a living organism, binomial nomenclature, and the tools required for the study of zoological parks, botanical gardens, etc.

It will also talk about the absorption and assimilation of proteins, carbohydrates, fats and other nutrients.
This chapter will also explain the different digestive disorders like vomiting, diarrhoea, jaundice, etc. Chapter 17 discusses our respiratory system. It talks about how the exchange of gases takes place as well as transportation of gases, regulation of respiration, respiratory volume, etc.
It will also explain the different respiratory disorders like emphysema, asthma, and occupational respiratory disorders. This chapter describes the composition of blood and talks about the blood groups and the coagulation of blood.
It will discuss how the circulatory system of the body works and the different disorders of the circulatory system like heart failure, angina pectoris, etc. Chapter 19 talks about the excretory system of the human body and also, the different modes of excretion like ureotelism, uricotelism, etc. The chapter helps students understand the function of kidneys, urine formation, and disorders like renal failure, renal calculi, etc.
What are the different kinds of movements in a living organism? This chapter enters in the world of muscles. It talks about the skeletal and muscular system and discuss the several disorders like tetany, arthritis, gout, etc.
Chapter 21 talks about the central nervous system of the body. It elaborates on generation and conduction of nerve impulses, sensory perception, reflex action, etc. It also provides details into the elementary structure of the sense organs like ear and eye. The final chapter in the Class 11 Biology NCERT book discusses, in detail, the different glands and hormones of our body and how they work.
It talks about the endocrine system and the role of hormones as messengers and regulators.

Fundamentals of Space Biology
It seems that you're in Germany. We have a dedicated site for Germany. This book is intended as an overview at the undergraduate or early university level and describes the effects of spaceflight at cellular and organism levels. Past, current, and future research on the effects of gravity--or its absence--and ionizing radiation on the evolution, development, and function of living organisms is presented in layman's terms by researchers who have been active in this field. The purpose is to enlighten science and non-science readers to the benefits of space biology research for conducting basic and applied research to support human exploration of space. Also covered are the advantages of approaching the space environment as a laboratory for scientific, technological, and commercial research.
had the chance to study a wide variety of plants and animals on continents and the next 10 years, he published important books on several different subjects.
