• 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 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 upto 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).

CUET Biology Preparation Tips

Though the syllabus of Biology consists of only 5 units, that does not mean that you can take this subject lightly as when you go into the detail of these 5 units, the syllabus tends to be vast. So, follow the below-mentioned CUET Preparation tips for the Biology exam:

• It is highly recommended to the candidates that they must stick to the syllabus first. If you pick up a unit such as Genetics and Evolution, complete all the possible topics of the unit mentioned in the syllabus so that you will be able to attempt every question from this unit.
• As CUET Exam is based on the syllabus of Class 12, it is advised that a candidate must go through the NCERTs quite carefully and thoroughly.
• As biology is a conceptual and theoretical subject, you must make sure that all your concepts are clear and up to the mark. Also, you need to be well-prepared with the diagrams of Biology as any question can be framed from within the diagrams.
• If you get stuck on a question, do not panic and waste your time on that specific question even if it is from your most prepared unit.
