The modes by which various organisms reproduce depend on the body design of the organisms. In asexual reproduction, a single individual parent produces offsprings without the involvement of gametes. This method is a common means of increasing the offsprings rapidly under favourable conditions. Asexual reproduction occurs mostly in unicellular organisms, some plants and certain simple multicellular animals.
(a)
Why is regeneration not same as reproduction ?
(b)
List any two advantages of producing plants through vegetative propagation.
(c)
(i)
