Read the paragraph and answer the questions given below:Reproduction is the process by which the living species continues its existence. Lower organisms carry out asexual reproduction while higher plants and animals always show sexual reproduction. Plants reproduce asexually by methods such as fragmentation, vegetative propagation, budding, spore formation. For sexual reproduction they form gametes. In animal kingdom, budding, fission of different types and parthenogenesis are some of the methods that do not require both the sexes. Though regeneration also forms new individual, it is not considered to be a reproductive process because, basically it is a repair process. The ability to regenerate is lost in higher phyla. In human beings | it is restricted only to wound healing. Sexual reproduction is also undergoing lots of experimentation such as cloning which may make females capable of producing their own baby without intervention of any male.i. How do living species continue their existence?ii. Which are asexual methods of reproduction in kingdom Animalia?iii. Why is regeneration not true method of reproduction?iv. What are methods of reproduction in plants?v. What is the modern method of reproduction aimed at in higher organisms?

Answer»

i. Through the process of reproduction, living species continue their existence.

ii. Fission, budding and parthenogenesis are the asexual methods of reproduction in Kingdom Animalia.

iii. Regeneration is the repair process than a reproductive process. It is not done with the intention of producing offspring, but is for healing or repairing the lost part.

iv. Plants reproduce by asexual as well as sexual methods. Asexual reproduction is by fragmentation, vegetative propagation, budding, spore formation, while by formation of gametes, sexual reproduction is done.

v. Cloning is the modern method of reproduction by which production of young one can be aimed at.
