1.

Reproduction

Reproduction in organisms:

Reproduction, characteristic feature

Modes of reproduction –Asexual and sexual; Asexual reproduction; Modes-Binary fission, sporulation, budding, gemmule, ragmentation; propagation in plants.

Sexual reproduction in flowering plants: Flower structure; Development of male and female

gametophytes; Pollination–types, agencies and examples; Outbreeding devices Pollen-Pistil interaction;

Double fertilisation; Post fertilisation 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).

2.

Genetics & evolution

Heredity and variation: Mendelian Inheritance; Deviations from Mendelism– Incomplete dominance, Codominance,

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's Syndrome, Turner’s andKlinefelter’ssyndromes.

MolecularBasisofInheritance:SearchforgeneticmaterialandDNAasgeneticmaterial;Structure Of DNAand RNA;

DNApackaging; DNAreplication;Central dogma; Transcription, genetic code,translation;Geneexpressionand

regulation–Lac Operon; Genome and human genome project; DNA fingerprinting.

Evolution: Origin of life; Biological evolution and evidences for biological evolution (Paleontological, comparative

anatomy, embryology and molecular evidence); Darwin’s contribution, Modern Synthetic theory of Evolution;

Mechanism Of evolution–Variation(Mutation and Recombination) and Natural Selection with examples types of natural

selection; Gene Flow and genetic drift; Hardy-Weinberg’s principle; Adaptive Radiation; Human evolution.

3.

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.

4.

Biotechnology and its Application

Principles and process of Biotechnology : Genetic Engineering(Recombinant DNA technology).

Application of Biotechnology health and agriculture : Human insulin and vaccine production, gene therapy;

Genetically Modified Organisms-Bt crops; Transgenic Animals; Biosafety Issues–Biopiracy and patents.

5.

Ecology and Environment

Organisms and environment: Habitat and niche; Population and ecological adaptations; Population interactions–

mutualism, competition, predation, parasitism; Population attributes–growth, birth rate and death rate, age

distribution.

Ecosystems: Patterns, components; productivity and decomposition; Energy flow; Pyramids of number, biomass,

energy; Nutrient cycling (carbon and phosphorous); Ecological Succession; Ecological Services– Carbon fixation,

pollination,oxygen release.

Biodiversity and its conservation : Concept of Biodiversity ; Patterns of Biodiversity ; 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 success stories addressing environmental issues.
