Question

How do roots take part in Vegetative propagation?

Answer 1

Hint: Reproduction is the essential system of any human being, mammals and organisms be it vertebrates or invertebrates. It possesses the ability to produce new organisms of their own species hence maintaining the line of its species and further life processes. Vegetative reproduction is a mode asexual reproduction. Asexual reproduction refers to the non-involvement of gametes or where no fusion takes place between individuals.

Complete answer:
Vegetative reproduction as we know also known as vegetative propagation or multiplication or cloning is any form of asexual reproduction occurring in plants in which new plant can grow from a plant part or from a fragment of plant. Many plants naturally reproduce this way but it can be grown or culture artificially too.
In some plants the vegetative propagation can be done through adventitious buds. These buds grow and form new plants or sprouts under the right conditions. These sprouts are detached from the parent plant and planted in other areas and then new plants are formed. For example- potato and dahlia. Also, root cutting is a type of artificial method. Horticulturalists techniques are being used to culture it or produce it artificially. This uses the vegetative parts to replicate plants. Success rates of being cultured such plants are very great.
There are two types of methods – natural means and artificial means. Natural means are- runners, bulbs, tubers, corms, suckers, plantlets, apomixis.
Artificial includes-grafting, cutting, layering, suckering, tissue culture etc.
Advantages of vegetative propagation are- mainly to produce offspring which are also called clones of their parents. Clones are basically the exact copies both genetically and morphologically similar individuals chopped off or came out of their parents.
Disadvantages of vegetative propagation- is that it prevents species genetic diversity, like the same line or lineage of species will continue to grow years after years until and unless artificially propagated. If naturally they propagate it maintains the genetic traits and avoids any kind of mutation or diversity which can be seen. The chances of getting diversity are less or rare.

Note:
Roots as we discuss are a medium of propagation through root cutting and it can develop into a whole new plant. All the tubers plant possess this quality to maintain their heredity line. Some examples of vegetative propagated crops are- strawberries, kalanchoe pinnata, rose, hibiscus. It can be economically beneficial and commercial too. It also possesses cost effectively and takes less time to reproduce.
