Unit I: Reproduction
In this unit, students will explore the fascinating world of reproduction. The syllabus covers various aspects of reproduction in both plants and humans. Topics include the structure of flowers, the development of male and female gametophytes, pollination, fertilization, post-fertilization events, and special modes of reproduction. Students will also learn about human reproduction, including the male and female reproductive systems, gametogenesis, menstrual cycle, fertilization, embryo development, pregnancy, parturition, and lactation. The syllabus also covers reproductive health, highlighting the need for reproductive health, prevention of sexually transmitted diseases, birth control methods, and assisted reproductive technologies.
Unit II: Genetics and Evolution
This unit focuses on the principles of inheritance and variation and the molecular basis of inheritance. Students will study Mendelian inheritance, deviations from Mendelism, chromosome theory of inheritance, sex determination, linkage, crossing over, and various genetic disorders. The syllabus also includes an introduction to molecular genetics, covering topics such as the search for genetic material, the structure of DNA and RNA, DNA replication, gene expression, and regulation. Furthermore, students will explore the concept of evolution, including the origin of life, evidence for biological evolution, Darwin’s contribution, mechanisms of evolution, and human evolution.
Unit III: Biology and Human Welfare
Students will learn about the relationship between biology and human welfare in this unit. They will learn about pathogens and parasites causing human diseases, basic concepts of immunology, cancer, HIV, AIDS, and drug and alcohol abuse during adolescence. The syllabus also covers the role of microbes in various fields, such as food processing, industrial production, sewage treatment, energy generation, and bio-control agents. Furthermore, students will explore the production and use of antibiotics.
Unit IV: Biotechnology and its Applications
This unit introduces students to the fascinating world of biotechnology and its applications. They will learn about the principles and processes of genetic engineering, including recombinant DNA technology. The syllabus also covers the application of biotechnology in health and agriculture, such as the production of human insulin and vaccines, stem cell technology, gene therapy, genetically modified organisms (GMOs), and biosafety issues. Students will also explore the concept of biopiracy and patents.
Unit V: Ecology and Environment
The final unit of the syllabus focuses on ecology and the environment. Students will study population interactions, population attributes, ecosystems, energy flow, and biodiversity conservation. They will learn about ecosystem patterns, productivity, decomposition, and ecological pyramids. Additionally, the syllabus covers the concept of biodiversity, its importance, the loss of biodiversity, and conservation measures. Students will also learn about hotspots, endangered organisms, the Red Data Book, sacred groves, biosphere reserves, national parks, wildlife sanctuaries, and Ramsar sites.
