An example of the rhizome is the iris. Examples of the tubers are potatoes, begonias, and dahlias. Ferns use spores to reproduce. These spores can be found on the underside of the leaves at certain times of the year. Ferns have transport vessels and have the capacity to grow as tall as trees.
Plants reproduce both sexually and asexually.
Propagation by the asexual method assures having new plants exactly like the parent and in a shorter period of time than the sexual reproduction. One type of asexual reproduction, vegetative reproduction, is possible because certain parts of some plants are capable of regeneration, or reproducing their missing parts. Bulbs, corms, rhizomes and tubers are all vegetative reproduction structures. Divide the class into groups of four. Each group picks a plant group of either corm, rhizome, or tuber to research their form of reproduction.
