i) Some plants follow the asexual or vegetative mode of reproduction wherein, the plants can reproduce via the root, stem, leaves etc of the plant and do not need the male and female reproductive parts to propagate.

ii) Bryophyllum is one such type which follows the vegetative mode of reproduction. It reproduces via the buds present along the notches of the leaf margin.

iii) These buds when fall off on the soil are able to grow into a new plant through vegetative reproduction.

iv) In case of the rose plant, the leaves do not produce such buds and hence this type of vegetative reproduction cannot take place. Rose plant follows the sexual mode of reproduction.

v) In the rose plant, the stamens and carpels which are the reproductive parts of the plant that contain the germ cells, are the ones responsible for its propagation.
