Different organisms reproduce by different methods suitable to their body designs.
(i) Justify the above statement using examples of two different organisms which reproduce by different methods of asexual reproduction,
(ii) Differentiate between sexual and asexual modes of reproduction.

Explanation

(a) (i) Binary Fission in Amoeba-In this method, the nucleus first divides amitotically into two, followed by the division of the cytoplasm. The cell finally splits into two daughter cells. So, from one Amoeba parent, two daughter amoebae are formed.
(ii) Budding in Hydra-In Budding, a small part of the body of the parents grows out as a .bud which then detaches and becomes a new organism. Hydra reproduces by budding using the regenerative cells. A bud develops as an outgrowth in Hydra due to repeated cell division at one specific site. When fully mature, the bud detaches itself from the parent body and develops into new independent individuals.
(iii) Regeneration in Planaria-In this method, small cut or broken parts of the organisms body grow or regenerate into separate individuals. Planaria can be cut into any number of picces and each piece grows into a complete organism.
(b) Difference between jenxas and Asexual
