Question

(a) Define vegetative propogation. List its two methods. (b) Why is this mode practised for growing some types of plants? (c) Explain the process of budding in Hydra.​

Answer 1

a)Vegetative propagation, or vegetative plant propagation, refers to the process of plant reproduction whereby a fragment of a parent plant (a cutting) is taken in order to produce more plants (clones). ... It is considered to be an asexual method

b)

Answer: Vegetative propagation method is used for growing certain plants which do not produce viable seeds. It is also used for growing of plants bearing superior traits, because they produce genetically identical plants. ... Plant which require lot of care during early stages of development are also grown by this method

c)

Shiza as hydra use regenerative cells for reproduction in the process of budding. In hydra, a bud develops as an outgrowth due to repeated cell division at one specific site. These buds develop into tiny individuals and, when fully mature, detach from the parent body and become new independent individuals.

Answer 2

Answer:

(a) Vegetative propagation is a form of asexual reproduction of a plant. Only      one plant is involved and the offspring is the result of one parent. The new plant is genetically identical to the parent.

   two methods

natural vegetative propagation

artificial vegetative propagation

(b) vegetative propagation is practiced for growing some plants because

   - Plants raised by vegetative propagation can bear flowers and fruits earlier than those produced from seeds

  -  It is also applied to plants such as banana,orange, rose and jasmine which have lost the capacity to produce seeds

  -  All plants produced by vegetative propagation are genetically similar to their parents.

(c)   Organisms such as hydra use regenerative cells for reproduction in the process of budding. In hydra, a bud develops as an outgrowth due to repeated cell division at one specific site. These buds develop into tiny individuals and, when fully mature, detach from the parent body and become new independent individuals
