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) State the name of the organism in which binary fission takes place in a definite orientation. Also name the disease caused by this organism.
(b) List any two advantages of producing plants through vegetative propagation.
(c) (i) Explain the process of budding in Hydra.
Solution
(a) Leishmania, Kala-azar
(b) Plants can bear fruits and flowers much earlier than produced by sexual reproduction
Plants produced are genetically similar to the parent plant
(Or any other)
(c)(i) Bud develops as an outgrowth due to repeated cell division at one specific site, these buds develop into tiny individuals, and when fully mature detach from the parent body and become new independent individuals.
