SET 2
Introduction
This set focuses on asexual reproduction in unicellular and simple multicellular organisms. It includes detailed questions on binary fission, multiple fission, budding, fragmentation, regeneration, and the role of specialised cells. The questions also cover experimental observations related to yeast, bread mould, and bacteria.
