Question

give the most important characteristic feature of organisms which reproduce by fragmentation can the multicellular organisms have Complex body organisation of body reproduce by this method. give reason​

Answer 1

Answer:

Spirogyra is one of such type of plant by fragmentation

Answer 2

Answer:

Important characteristic feature for fragmentation:

The process of fragmentation occurs due to the presence of specialized tissues which is responsible for such type of asexual reproduction. One best example of organism that undergo fragmentation is Spirogyra.

Fragmentation is a process of asexual reproduction, in which an organism splits up into fragments and each fragment propagates to form a new organism.

Fragmentation in complex organisms:

In case of complex organisms, the process of fragmentation is not possible. Complex organisms do not reproduce through fragmentation. This is because, these organisms lack those specialized tissues that are responsible for fragmentation.

However, some organisms undergo regeneration. In this type of reproduction the accidentally cut part of an organism grows back to original form through the regenerative cells and tissues. Lizard is an example of this type.

In case of lower organisms, this method itself serves as a method of asexual reproduction. Some examples of organisms that undergo regeneration are Planaria, hydra etc..,
