Question

In some organisms the body breaks into distinct pieces and each fragment grows into an adult capable of producing offspring. This is also a mode of asexual reproduction called

• A. Encystation
• B. Fragmentation
• C. Binary fission
• D. Sporulation

Answer 1

The correct option is B Fragmentation

Asexual reproduction
Asexual reproduction is the process of producing offspring from a single parent, without involving the fusion of gametes. Sporulation, fragmentation and binary fission are different types of asexual reproduction.

Sporulation
Sporulation is a mode of asexual reproduction that occurs in Amoeba during unfavorable conditions. $Amoeba$ withdraws its pseudopodia and develops a tough wall around itself known as cyst . The process is called encystation.The encysted $Amoeba$ divides by multiple fission to form pseudopodiospores. When favourable conditions return, the pseudopodiospores are released due to rupturing of the cyst and each of them give rise to new amoebae.


Fragmentation
In fragmentation, the body of the parent organism breaks into many fragments each, which later grows into new individuals. For example $Spirogyra$ etc.


Binary fission
Binary fission is a method of asexual reproduction in which the nucleus elongates and divides into two followed by division of cytoplasm, giving rise to two daughter cells.


Final answer
(c) Fragmentation
