$\huge\star{\green{\underline{\mathfrak{Answer :-}}}}$

• Asexual reproduction is the type of reproduction in which only one individual is involved.
• Here, no gametes are involved,but some part of the organism or the entire organism may give rise to the new individual.
• The types are as follows :

1. Fission
2. Budding
3. Regeneration
4. Fragmentation
5. Spore Formation
6. Vegetative Reproduction

FISSION :

• In pigeon, the organism divides or splits into two or more parts.
• There are two types of fission namely binary fission and multiple fission.
• The binary fission is shown in amoeba and leishmania.
• These organism divide into two new organisms during division.
• The multiple fission is shown in plasmodium.
• During division, the plasmodium divides into many daughter cells simultaneously.
• The yeaat on the other hand, put out small buds with separate and grow further.

FRAGMENTATION :

• This is shown in Spirogyra.
• After maturation, it simply breaks up in two different small pieces.
• The new fragments further grow into new individuals.

REGENERATION :

• Many organisms have the ability to give rise to new individual organisms from their body parts.
• The examples include hydra and planaria.
• Planaria can be cut into any number of pieces and each piece will grow into a new complete organism.
• It can only be carried out by specialised cells.

BUDDING :

• Organisms like hydra, develops a bud as an outgrowth due to repeated cell division.
• These buds, father detached from the parent body after getting fully matured and become new independent individual.

VEGETATIVE PROPAGATION :

• There a lot number of plants which grows with the help of different parts of a plant in some appropriate conditions.
• This property of vegetative propagation is used in the methods of layering and grafting to grow many plants for agricultural purposes.
• These methods make possible the propagation of plants such as fruit plants that have lost the capacity to produce seeds.
• Theother advantage of it is that all the plants produced are genetically similar enough to the parent plant to have its characteristics.
• This also includes the bryophyllum leaf.
• In a bryophyllum leaf, small buds are produced in the notice along the leaf margin.
• These buds, fall on the soil and develop a new plant.
