Fertilization and development
निषेचन और भ्रूणीय विकास
In this Class 10 Science topic from “How do Organisms Reproduce?”, students learn how fertilization occurs when a sperm fuses with an ovum to form a zygote. They follow the zygote’s early divisions, implantation in the uterus, and development of the embryo and foetus, while understanding the roles of the uterus, placenta, and umbilical cord in nourishment and exchange. The topic connects human reproductive processes with the beginning of a new individual.
