Key Components of the CUET 2025 Biology Syllabus

CUET Biology Syllabus 2025 has only five units to be covered from the CUET exam point of view.

The essential units and subtopics for CUET 2025 Biology Syllabus 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 propagation in plants.
