Question

how many types of asexual reproduction are there?what are they.

Answer 1

Asexual reproduction is of six types

The types are

1.Budding

2.Fragmentation

3.Spore Formation

4.Vegetative propagation

5.Binary Fission

6.Regeneration

Budding:- Budding is a type of reproduction which takes in yeasts which is a single celled organism. It sends out one or more tiny outgrowths which are known as buds. The buds may stockpile to form chains of buds. The nucleus of the yeast cell is divided and is passed on to each of the buds. The buds upon fully developing are cut of from the yeast cell and become new individual organisms,

Fragmentation:- Fragmentation takes place in filamentous algae such as the spirogyra. The algae is divided into two parts by the running water, then the new part develops into a new organism.

Spore Formation:- Spores are asexual reproductive organs found in plants such as ferns or moss. The spore settles over a hyphae(a thread like structure) then creates new spores which are protected by a thick covering known as the sporangium which is borne on a stalk known as the sporangiophore. The spores can be released at any time and can be carried anywhere. Upon finding suitable conditions they may germinate.

Vegetative propagation:- Vegetative propagation takes place in advanced plants through their vegetative organs. The flower is not involved. Some plants like potato store food to survive through adverse conditions. There are various examples of vegetative propagation taking place in plants some of them are :- Root Tuber,Rhizome,Tuber,Runner,Foliar Buds etc.

Binary Fission:- In Binary Fission the organism’s Dna is duplicated . it then divides in two(via cytokinesis) with each copy receiving one copy of the Dna. Amoeba reproduces by this process.

Regeneration:- In this process , a broken part of the organism(which broke accidentally) develops into a complete organism.Planaria reproduces by this process

Hope this helps you

Answer 2

Asexual Reproduction- The production of new organism from a single parent without the involvement of sex cells is called asexual reproduction.

There are six different types of asexual reproduction-

1. Fission

2. Budding

3. Spore formation

4. Regeneration

5. Fragmentation

6. Vegetative propagation.
