Among the statements given, which are the disadvantages of natural vegetative propagation?
a) Lack of dispersal mechanisms
b) No fertilization is involved
c) The area is quickly colonized
d) Offspring are exact clones of parent plants.

Correct Answer: (a) Lack of dispersal mechanisms and (d) Offspring's are exact clones of parent plants

Explanation:

Vegetative propagation is an asexual method of reproduction in which plants can grow and reproduce from stems, roots, and leaves.

The new plants can grow from the detached part (stems, roots, and leaves) of the plant because it has sufficient cells to divide and produce a new individual.

Examples of Vegetatively propagated plants:

Through Stem - Mint, Rose, and Sugarcane

Through Roots - Sweet Potato, Yam, and Dahlia

Through Leaves - Begonia and Bryophyllum

Advantages of Vegetative Propagation are:

• Vegetative propagation helps in maintaining the characteristic features of the parent plant.
• Cultivation of plants through vegetative propagation consumes less time.
• Vegetative reproduction helps in bringing the desired characteristics of the plant such as immunized to diseases through budding and grafting.
• It helps to develop plant varieties with useful characteristics and is also helpful for plant that rarely produces flowers.

Disadvantages of Vegetative Propagation are: 

• Genetic variation is not observed in the plants propagated vegetatively and thus plants are less adaptable to the environment.
• As plants are a copy of the parent plant, diseases of the parents' plants are transferred to offspring.
• As it is an asexual method of reproduction, it does not involve pollination and mating among varied plants. This can lead to decreased rate of genetic variation and ultimately fewer chances of evolution and survival.
