Clone is
- Descendants of a single parent
- Vegetatively produced descendants of a single parent

- All the above
Clones are individuals obtained through
- Self pollination
- Cross pollination
- Vegetative propagation

Which one of the following statements is not correct regarding vegetative propagation?
- Vegetative propagation produces clonal population
- Micro propagation is the fastest technique of vegetative propagation
- Vegetative propagation can go on round the year
- Vegetative propagation helps to eliminate the vrius
The most significant feature of vegetative propagation is that
- It enables rapid production of genetic variation
- It is a means of producing a large population of individuals genetically identical to the parent
- It ensures that the progeny are safe from attack of diseases and pests
- It is an ancient practice
Offspring produced by vegetative propagation are
- haploid
- triploid
- genetically identical
- superior to offspring produced by sexual reproduction
Which of the following is not a vegetative part of plant?
- Carpel
- Thalamus
- Stipules
- Calyx

A. There are some plants which have in their life-cycles neither the process of fertilization nor they have meiosis.
R. In these plants, the vegetative or somatic plant body helps in the propagation of the plant.
