Key Components of the CUET Biology Syllabus

The essential units and subtopics for the CUET syllabus Biology are as follows- 

Unit I: Reproduction 

Reproduction in organisms

• Reproduction is a characteristic feature of all organisms for the continuation of species;
• Modes of reproduction –Asexual and sexual; Asexual reproduction;
• Modes- Binary fission, sporulation, budding, gemmule, fragmentation; vegetative plant propagation. 

Sexual reproduction in flowering plants

• Flower structure; Development of male and female gametophytes;
• Pollination–types, agencies and examples; Out breeding's 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.
