Question

Mention the disadvantage of vegetative propagation.

Answer 1

Hint: Seeds are not always necessary for plants to grow. Vegetative propagation such as grafting and budding, etc. help in growing new plants from vegetative sections of the older plants. It's a reproductive asexual process.

Complete answer:
Disadvantages of vegetative distribution
-The vegetatively propagated plants are short-lived, tiny compared to the propagated seeds.
-No new varieties may be produced
-Skilled people are needed and often costly compared to seed propagation.
-More vulnerable to disease, as the whole plant can be affected, as there is no genetic variation.

Additional Information: - The vegetative reproductive structures in non-vascular plants are gemmae and spore, while the structures involved in transplantation are roots, tribulations, leaves, and nodes in vascular plants. The structure of meristem has been studied in plants. The same tissue contributes to the growth of plants. This tissue is made up of undifferentiated cells that pave the way for plant growth. Various permanent tissues are formed from meristems.

Plant growth is the plant breeding period of a crop or cultivar which may be sexual or asexual through the use of vegetative parts such as leaves, stalks, and roots for new plants or through the development of particular vegetative sectional plants. Plant breeding can occur. While many plants reproduce by vegetative breeding, this type is seldom used exclusively for breeding purposes. When it allows plants to produce more offspring per resource unit than through seed development, vegetative reproduction is favored. Usually, young plants are more difficult to reproduce vegetatively.

Note:
- Morphologically and genetically similar descendants are produced in vegetative reproduction.
- Potentially, vegetative propagation is something very special to plants. The same attribute is often used for commercial value and for passionate gardeners who know their plants well.
- Vegetative reproduction is not evolutionary; it does not require genetic diversity and can lead to deleterious mutations in plants.
