Chapter 1 of Class 12 Biology, "Reproduction in Organisms," covers the fundamental processes through which living organisms reproduce to ensure the continuation of their species. It discusses the two main modes of reproduction: **asexual** and **sexual**. Asexual reproduction involves a single parent, resulting in offspring that are genetically identical to the parent, with methods like binary fission, budding, and fragmentation. Sexual reproduction, on the other hand, involves two parents and the fusion of male and female gametes, leading to genetic variation in the offspring. The chapter also highlights the reproductive phases in organisms, including juvenile, reproductive, and senescent stages.
