The candidates can check the CUET 2025 Biology syllabus PDF in online mode and can also check it below.

CUET Biology Syllabus 2025

The CUET Biology syllabus covers important topics in life sciences. It includes the study of cells, which are the basic units of life, and genetics, which explains how traits are passed from parents to offspring. The CUET Biology Syllabus 2025, consists of 5 units which consist of 16 chapters. Each unit carries several chapters or sub-topics. As per the released notification, section II, or the domain-subject section, carries 50 questions, out of which candidates will have to attempt 40 questions. The total time duration for this section is 45 minutes.

Students also learn about the structure and function of plants and animals, including how they grow and reproduce. Additionally, the syllabus covers human biology, such as the digestive, respiratory, and circulatory systems. Topics like ecology, which is the study of how living things interact with their environment, and evolution, which explains how species change over time, are also included.

CUET 2025 Unit Wise Biology Syllabus

The Students are advised to first go through the newly updated CUET syllabus before starting their preparation for the Common University Entrance Test [CUET]. The CUET 2025 Biology Syllabus has been discussed below, which covers almost all the topics of Biology.

Unit I: Reproduction

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; 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 syndrome, Turner’s and Klinefelter’s syndromes.
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, 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’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, ring worm); 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.
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 (Recombinant DNA technology).
Application of Biotechnology in Health and Agriculture: Human insulin and vaccine production, gene therapy; Genetically modified organisms-Bt crops; Transgenic Animals; Biosafety 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 and death rate, age distribution.
