Question

Discrib the various methods of asexual reproduction

Answer 1

Answer:

There are several different methods of asexual reproduction. They include binary fission, fragmentation, and budding.

Binary fission occurs when a parent cell splits into two identical daughter cells of the same size.

The definition of fragmentation is being broken down into sections. An example of fragmentation is cutting a worm into pieces.

Answer 2

・❥・Different methods of asexual reproduction  :-

• Binary fission- The process in which parent  cell elongates and gets divided into two  identical daughter cells is called binary fission.  Each daughter cell grows into an independent  adult. It takes place in unicellular organisms.

• Endospore Formation- The method in which  a spore wall is formed around a bacterial cell to  form an endospore is called endospore  formation. Under favorable conditions, this  endospore germinates to form an active  bacteria.

• Vegetative propagation- The type of  asexual reproduction in which vegetative parts  of a plant like stems, leaves, and root, etc. give  rise to new ones is called vegetative  propagation.  

Examples: stem cutting in Champa, eye growth  in potatoes, bud in case of Myriophyllum.

• Budding: It involves the formation of a new  organism from a projection called bud. After  growing to full size, the budgets detached from a  parent and forms a new independent individual.  It is commonly observed in yeast.

• Spore Formation: In this mode of  reproduction, spores germinate and develop  into a new individual, under favorable conditions.  The spores are tiny spherical unicellular  structures protected by a thick wall. It is seen in  ferns and moss.

• Fragmentation: It is a form of asexual  reproduction in which a new organism is formed  from the fragments of the parent organism. It is  the only mode of asexual reproduction in  Spirogyra.
