Question

what is asexual reproduction explain its types please answer this

Answer 1

HEYA. ....
Asexual reproduction is the method of reproduction in which there is no involvement of gametes and in other way we can say it avoids syngamy( Fusion of gametes)..
It is mostly shown by unicellular organism but few multicellular also show.
For example
Amoeba :- Binary Fission+ Multiple Fission
Planaria:- Regeneration/ Fragmentation
It also includes Vegetative methods
1) Cutting
2) Grafting
Hope it helps;;;!;;;;

Answer 2

Hey dear

☻ Asexual reproduction ☻

Formation of new individuals from the cells of a single parent known as asexual reproduction.

● Types of asexual reproduction.

There are major 6 types of asexual reproduction :-

1 ) = Binary fission

2 ) = Fragmentation

3 ) = Budding

4 ) = Spore formation

5 ) = Regeneration

6 ) = Vegetative propagation.

● Fission

There are two of Fission :-

1 ) = Binary Fission

2 } = Multiple Fission

● Binary fission

Fission means " splitting into two "In binary fission the nucleus of the Amoeba rapidly divides into two nucleic after the division of cytoplasm , the two daughter cells are formed.

Two examples of binary fission = Amoeba and Leishmania.

2. Multiple fission

The parent cell divides into many daughter cells.

e.g.Plasmodium.

● Fragmentation

It is the accidental process when broken pieces of an organism grows in a complete organism.

It occurs in multicellular organism.

Two examples are :-Lichens , Flatworms

● Budding

The process by which a bud develops as a outgrowth on parent body.

When these buds become mature these buds detach from the parent body.

Two examples are :- Hydra and Yeast

● Spore formation

Spores are covered by thick walls they protect them until they come in contact with suitable conditions.

They produce new individuals under favourable conditions

Two examples are - Ferns , Mosses

● Regeneration

When simple animals develop a new individuals from their broken older parts it is known as regeneration.

Two examples of regeneration are - Planaria , Sea Star

● Vegetative propagation

In vegetative propagation reproduction takes place from the vegetative parts like stem , roots and leaves.

Method for vegetation propagation

● Natural

1 ) = By grafting - Dahlias

2 ) = By stems - potatoes

3 ) = By leaves - Bryophyllum

● Artificial

1 ) = Grafting - Mango

2 ) = Cutting - Rose

3 )= Layering - Jasmine
