Reproduction

In this Class 10 Science topic from the “World of Living” chapter, students explore how organisms produce new individuals and why reproduction is essential for the continuation of life. They compare asexual and sexual reproduction, study reproductive processes in plants and humans, and understand puberty, the human reproductive system, fertilisation, menstruation, and basic reproductive health. The topic also introduces contraception and the role of responsible choices in preventing unwanted pregnancy and sexually transmitted infections.
