explain different methods of asexual reproduction with the help of diagrams

Budding : In budding the no. of offspring plants will be identical to  parents. In budding an outgrowth develops from the parent which then detaches from the main parent body to form offspring. One cell from the parent body divides by mitosis and then detaches from it. Example: Each potato tuber has several eyes or buds where each bud can grow into a separate potato plant.

Fragmentation : It is a type of an asexual method of reproduction where, an organism such as an alga breaks up into smaller fragments. Each of these smaller fragments grows into a new independent alga.

Cutting- It is a technique of vegetative propagation in plants where a cutting is made from piece of the parent plant - stem, root or leaf, and planted it in a suitable medium. The nodal region of the stem is preferably taken.

Grafting- Grafting is a process commonly used in asexual propagation techniques where a part of one plant is joined to the stump of another plant. Portion of the stem with many buds is taken and this portion is known as scion. The stump to which the scion is attached is called the stock.

Layering- Layering is a method of propagating a plant by growing roots through bending and nailing down a portion of an aerial stem to the ground while still attached to the parent plant. Once the roots develop, the branch is then cut off from the parent body. The branch that produces the roots is called the layer.

Asexual reproduction - Wikipedia, the free encyclopedia

Asexual reproductionis a mode ofreproductionby which offspring arise from a single parent, and inherit the genes of that parent only; it is reproduction which almost never involvesmeiosis,ploidyreduction, orfertilisation. The offspring will be exact genetic copies of the parent, except in the specific case of automixis. A more stringent definition isagamogenesiswhich is reproduction without the fusion ofgametes. Asexual reproduction is the primary form of reproduction forsingle-celled organismssuch as thearchaebacteria,eubacteria, andprotists. Manyplantsandfungireproduce asexually as well.

Different types of asexual reproduction are:-

1. Fission:- in this type of asexual reproduction the parental cell divides into two (binary fission) or more (multiple fission) daughter cells. Example:- Bacteria (binary fission) and Protists (multiple fission).2. Budding:- Some cells of the parental body extend outwards and form a bud like structure that later on separates from the body and give rise to a new organism. Example:- Hydra.3. Vegetative propagation:- This type of reproduction usually occurs in plant, different vegetative parts of the plants like bulbs, tuber, rhizomes give rise to a new plant. Example:- Leaf buds in Bryophyllum.5. Fragmentation:- Parental body get fragmented and each fragment give rise to a new organism. Example:- Spirogyra.6. Spore formation:- In this type of asexual reproduction new organism arise from spores. Example:- Mosses and Ferns.
