Question

What is plasmotomy? Give two examples of it.

Answer 1

Hint:In asexual mode of reproduction, new offsrpings are produced without the fusion of male and female gametes. Usually only a single parent is involved.

Complete answer:
Let us first know more about asexual mode of reproduction. In asexual mode of reproduction only a single parent is involved and the offspring is both physically and genetically identical to each other and the parent.
The characteristics of asexual mode of reproduction are:-
>The offsprings are genetically similar
>The rate of reproduction is faster
>Only single parent is involved
>The time period for reproduction is small

Now, coming to plasmotomy. It is a mode of asexaul reproduction which is commonly seen in protozoa. The word plasmotomy means uncountable.
In many multinucleated organisms, the cells divide and they form multiple nuclei without undergoing the process of mitosis and this is known as plasmotomy. The multinucleated cells further divide into similar daughter cells.
In and all, plasmotomy can be defined as the process by which the parent organism divides into daughter organism or offspring without undergoing the process of mitosis.

Examples: Plasmodium and Opalina

Note:The advantage of asexual reproductiona are,
>There is no requirement of two parents, as only one parent is enough.
>The rate of reproduction is fast.
>Huge amounts of offspring can be produced in a short period of time.
>It can occur in different and diverse environments.
>The positive and useful genes can be transmitted to the offspring.
