Question

explain any two methods of asexual reproduction​

Answer 1

Answer:

Asexual reproduction includes fission, budding, fragmentation, and parthenogenesis, while sexual reproduction is achieved through the combination of reproductive cells from two individuals.

The ability of a species to reproduce through fragmentation depends on the size of part that breaks off, while in binary fission, an individual splits off and forms two individuals of the same size.

Budding may lead to the production of a completely new adult that forms away from the original body or may remain attached to the original body.

Observed in invertebrates and some vertebrates, parthenogenesis produce offspring that may be either haploid or diploid.

Sexual reproduction, the production of an offspring with a new combination of genes, may also involve hermaphroditism in which an organism can self-fertilize or mate with another individual of the same species.

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.
