Understanding every chapter in complete detail for class 12 biology  

Biology might be the most pleasant and delightful experience for you if you use the proper learning strategy. We use the most efficient study approaches at Infinity Learn to make studying more enjoyable. In class 12th Biology, there are various chapters, and you can access and download chapter-by-chapter NCERT Solutions for Biology Class 12 PDF from Infinity Learn. The following are the class 12 biology chapter covered in NCERT Solutions.

Reproduction in Organisms (Chapter 1)

The procreation process of many species is discussed in the chapter Reproduction in Organisms. Reproduction is the biological process through which organisms give birth to their offspring. There are two sorts of processes in this category. The first is asexual reproduction, in which only the children are reproduced.

Sexual Reproduction in Flowering Plants (Chapter 2)

This chapter examines the structure, morphology, and mechanisms of sexual reproduction in flowering plants. Pre-fertilization: Structure and Events, Port fertilisation: Structure and Events, Double fertilisation, Polyembryony, and Apomixis are among the topics covered. The biology solution class 12 can help you with proper understanding of these concepts and chapters.

Reproduction in Humans

The reproductive events in humans are explained in the Human Reproduction chapter. This involves the process of gametogenesis (the formation of gametes). Humans acquire sexual maturity when they reach puberty. Males and females go through separate reproductive processes. In this chapter, you will be able to investigate these differences. The female reproductive system, the male reproductive system, fertilisation and implantation, menstrual cycle, gametogenesis, embryonic development and pregnancy, breastfeeding, and parturition are all covered in this chapter.

Inheritance and Variation Principles

One of the numerous disciplines of biology is genetics. It’s about heredity and how children’s personalities differ from their parents’. Characters are passed on from parents to their children in the inheritance process. Mendel’s various Laws of Inheritance, Sex Determination, Inheritance of One Gene or Two Genes, Genetic Disorders, and Mutation are all covered in depth in this chapter.

Inheritance’s Molecular Basis

The inheritance patterns as well as the genetic basis for these patterns were covered in previous chapters. The factors that regulated the inheritance pattern were unknown during Mendel’s time. However, throughout the next century, scientists made significant progress in understanding the nature of putative genetic material. It led to the discovery that most species’ genetic material is Deoxyribonucleic Acid (DNA). Nucleic acids were polymers of nucleotides, according to the XI curriculum. The DNA, RNA World, Search for Genetic Materia, Genetic Code, Transcription, Replication, Translation, Human Genome Project, DNA Fingerprinting, and Regulation of Gene Expression will all be covered in this chapter.


The area of evolutionary biology is concerned with the study of the evolution of life on Earth. The Origin of Life, Evolution – A Theory, Evidence for Evolution, Adaptive Radiation, Mechanisms of Evolution, Biological Evolution, Hardy Weinberg Principle, Origin and Evolution of Man, and other subtopics are covered in the Evolution Chapter.

Enhancement Strategies for Food Production

Due to population growth, there is a greater need to improve food production processes. Biological concepts used in plant breeding and animal husbandry have a significant impact on the food production process. Several tools, like as tissue culture and embryo transfer technologies, can help to improve this process even more. Tissue Culture, Animal Husbandry, and Single Cell Technology will all be covered in the chapter on Food Production Enhancement Strategies.

The Role of Microbes in Human Welfare

Microbes, in addition to macroscopic animals and plants, are an important component of biological systems. Students studied about living creatures and their diversity in earlier sessions. Bacteria, protozoa, fungus, and small plant and animal viruses are all examples of microbes. On nutritive media, microbes such as fungus and bacteria may grow and form colonies that are visible to the naked eye. When investigating microorganisms, these cultures are quite valuable. Microbes in Industrial Products, Microbes in Household Products, Microbes in Biogas Production, Microbes in Sewage Treatment, Microbes as Biofertilizers, and Microbes as Biocontrol Agents are all covered in depth in this chapter.

Principles and Procedures of Biotechnology

Biotechnology is a branch of science that deals with the use of enzymes from living creatures to create processes and products that are helpful to people. Biotechnology, according to the European Federation of Biotechnology’s (EFB) definition, includes both conventional and modern molecular biotechnology. It is the application of natural science to organisms, cells, and molecular counterparts in order to provide services and goods. This chapter will address topics such as Biotechnology Principles, Recombinant DNA Technology Tools and Processes, and so on.


Infinity Learn not only provides study resources for the Science stream, but also for other courses and classes. All of the resources are written in simple language to make it easier for pupils to grasp. For other entrance examinations like as NEET, JEE, and others, our specialists also conduct live seminars, lectures, and give study resources.

Even during the session, if you are uncomfortable or have a problem with our answers, or if you need assistance with any other concepts or concerns, you are welcome to ask without hesitation. Our specialists will be available to you at all times until all of your questions are answered.
