Unit I: Reproduction
Reproduction in organisms: Reproduction, is a characteristic feature of all organisms for continuation species;
Modes of reproduction –Asexual and sexual; Asexual reproduction; Modes- Binary fission, sporulation, budding, gemmule, fragmentation; vegetative propagation in plants.
Sexual reproduction in flowering plants: Flower structure; Development of male and female gametophytes; Pollination–types, agencies, and examples; Outbreedings devices; Pollen-Pistil interaction; Double fertilization; Post fertilization events– Development of endosperm and embryo, Development of seed and formation of fruit; Special modes– apomixis, parthenocarpy, polyembryony; Significance of seed and fruit formation.
Human Reproduction: Male and female reproductive systems; Microscopic anatomy of testis and ovary; Gametogenesis- spermatogenesis & oogenesis; Menstrual cycle; Fertilisation, embryo development up to blastocyst formation, implantation; Pregnancy and placenta formation (Elementary idea); Parturition (Elementary idea); Lactation (Elementary idea).
Reproductive health: Need for reproductive health and prevention of sexually transmitted diseases(STD); Birth control- Need and Methods, Contraception and Medical Termination of Pregnancy (MTP); Amniocentesis; Infertility and assisted reproductive technologies – IVF, ZIFT, GIFT (Elementary idea for general awareness).
Unit II: Genetics and evolution
Heredity and variation: Mendelian Inheritance; Deviations from Mendelism– Incomplete dominance, Co-dominance, Multiple alleles and Inheritance of blood groups, Pleiotropy; Elementary idea of polygenic inheritance; Chromosome theory of inheritance; Chromosomesandgenes; Sex determination–Inhumans, birds, honeybee; Linkage and crossing over; Sex-linked inheritance- Haemophilia, Colour blindness; Mendelian disorders in humans– Thalassemia; Chromosomal disorders in humans; Down syndrome, Turner’s andKlinefelter’ssyndromes.
Molecular Basis of Inheritance: Search for genetic material and DNA as genetic material; Structure of DNA and RNA; DNA packaging; DNA replication; Central dogma; Transcription, genetic code, translation; gene expression and regulation–Lac Operon; Genome and human genome project; DNA fingerprinting.
Evolution: Origin of life; Biological evolution and evidence for biological evolution (Paleontological, comparative anatomy, embryology, and molecular evidence); Darwin’s contribution to, Modern Synthetic theory of Evolution;
Mechanism of evolution–Variation(Mutation and recombination) and Natural Selection with examples, types of natural selection; Geneflowandgeneticdirft; Hardy-Weinberg’sprinciple; Adaptive Radiation; Human evolution.
Unit III: Biology and human welfare
Health and Disease: Pathogens; parasites causing human diseases (Malaria, Filariasis, Ascariasis, Typhoid, Pneumonia, common cold, amoebiasis, ringworm); Basic concepts of immunology–vaccines; Cancer, HIV and
AIDs; Adolescence, drug and alcohol abuse.
Improvement in food production: Plant breeding, tissue culture, single cell protein, Biofortification; Apiculture and Animal husbandry.
Microbes in human welfare: In household food processing, industrial production, sewage treatment, energy Generation, and as biocontrol agents and biofertilizers.
Unit IV: Biotechnology and its applications
Principles and process of Biotechnology: Genetic Engineering (RecombinantDNAtechnology).
Application of Biotechnology in health and agriculture: Human insulin and vaccine production, gene therapy;
Genetically modified organisms-Bt crops; Transgenic animals; bio-safety issues–Biopiracy and patents.
Unit V: Ecology and environment
Organisms and environment: Habitat and niche; Population and ecological adaptations; Population interactions–mutualism, competition, predation, parasitism; Population attributes–growth, birth rate, death rate, age distribution.
Ecosystems: Patterns, components; productivity and decomposition; Energy flow; Pyramids of number, biomass, energy; Nutrient cycling (carbon and phosphorous); Ecological succession; EcologicalServices– Carbon fixation, pollination, oxygen release.
Biodiversity and its conservation: Concept of biodiversity; Patterns ofBiodiversity; Importance of Biodiversity; Loss of Biodiversity; Biodiversity conservation; Hotspots, endangered organisms, extinction, Red Data Book, biosphere reserves, National parks, and sanctuaries.
Environmental issues: Air pollution and its control; Water pollution and its control; Agrochemicals and their effects; Solid waste management; Radioactive waste management; Greenhouse effect and global warming; Ozone depletion; Deforestation; Any three case studies as success stories addressing environmental issues.
