CUET examination will be conducted by National Testing Agency for the Year 2022-23.
Unit I: Reproduction.
Reproduction in organisms: Reproduction, a characteristic feature of all organisms for continuation of 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 ofseed
andfruitformation.
Human Reproduction: Male and female reproductive systems; Microscopic anatomy of testis and ovary;
Gameto genesis- spermatogenesis & oogenesis; Menstrual cycle; Fertilisation, embryo development upto
blastocyst formation, implantation; Pregnancy and placenta formation (Elementary idea); Parturition
(Elementaryidea);Lactation (Elementaryidea).
Reproductive health: Need for reproductive health and prevention ofsexually 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 polygenicinheritance; Chromosome
theory of inheritance; Chromosomes and genes; Sex determination – In humans, 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 and Klinefelter’s syndromes.
Molecular Basis of Inheritance: Search for genetic material and DNA as genetic material; Structure of DNAand RNA;
DNA packaging; DNA replication; Central dogma; Transcription, genetic code, translation; Geneexpression and
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 dirft; Hardy Weinberg’s principle; Adaptive Radiation; Human evolution.
Unit III: Biology and Human Welfare Health an d Disease:
Pathogens; parasites causing human diseases (Malaria, Filariasis, Ascariasis, Typhoid,
Pneumonia, common cold, amoebiasis, ring worm); Basic concepts of immunology–vaccines;Cancer, HIV and
AID's; Adolescence, drug and alcohol abuse.
Improvement in food production: Plant breeding, tissue culture,single cell protein, Bio fortification; Apiculture and
Animal husbandry.
Microbes in human welfare: In household food processing, industrial production, sewage treatment, energy
generation and as bio control agents and bio fertilizers.
Unit IV: Biotechnology and Its Applications.
Principles and process of Biotechnology: Genetic engineering (Re combinant DNA technology).
Application of Biotechnology in health and agriculture: Human insulin and vaccine production, gene therapy;
Genetically modified organisms - Bt crops; Transgenic Animals; Bio safety issues–Bio piracy 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 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; Hot spots, endangered organisms, extinction, Red Data Book, biosphere
reserves,National parks and sanctuaries.
Environmental issues:Air pollution and its control;Water pollution and its control; Agro chemicals 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.
