1. On what factors does the type of reproduction adopted by an organism depend on?[NCERT Exemplar] Answer: The organism’s habitat, physiology and genetic make-up determines the type of reproduction adopted by it. 2. What is asexual mode of reproduction? The mode of reproduction in which formation and fusion of gametes does not take place is called asexual reproduction. Only somatic part is involved in such reproduction. Define clone. Clone is a group of individuals of the same species that are morphologically and genetically similar. Name the type of fission with examples. Binary fission — Amoeba Transverse fission — Paramecium Multiple fission — Plasmodium What is budding? It is a mode of asexual reproduction in which one or more outgrowths (buds) protrude out, which later get detached from the parent body to grow into a new individual, e.g., yeast. Name one organism where chain budding is found. Yeast Mention two inherent characteristics of Amoeb...
