explain different methods of asexual reproduction with the help of diagrams
Answers
a) binary fission eg ameoba
b) multiple fission eg plasmodium
(in this process one organism in divided into its daughter cells)
2) fragmentation eg Spirogyra
(get divided when matured and each fragment is converted into new individual)
3)regeneration eg Planeria
(accidentally get divided to form new individual)
4)budding eg hydra
(a organism have a out grown bud, which gets deattaches from the plant and formed new individual)
5)vegetative propagation
a) cutting eg bryophyte
b) layering eg jasmine
c ) grafting eg green apple
(new plant is grown with part of parent plant
6)spore formation eg rhizobus
Reproduce by spores

The various modes of asexual reproduction in plants are as follows:
(i)Vegetative propagation: It is the ability of a plant to produce new plants from roots, stems, leaves, and buds. Vegetative propagation is divided into two types.
• Natural vegetative propagation: This type of vegetative propagation occurs easily in nature and involves simple vegetative parts. Potato plant sprouting from an eye is a common example.
• Artificial vegetative propagation: This type of vegetative propagation is performed manually and generally occurs in laboratory conditions. The formation of a complete plant from a stem cutting of rose is a common example of this method.
(ii) Budding:It involves the formation of a new individual from a bulb-like projection called a bud. The bud grows and gets detached from the parent to form a new individual. It is commonly observed in yeast.
(iii)Fragmentation:It is a form of asexual reproduction where a new organism is formed the fragments of the parent body. It is the only mode of asexual reproduction in Spirogyra.
(iv)Spore formation:Many non-flowering plants reproduce through spore formation. Spores are tiny cells protected by a thick wall. Fungi such as bread moulds reproduce asexually using this method.
