Name an example of a plant that reproduces through rhizomes.

Bamboo is an excellent example of a plant that reproduces through rhizomes. Rhizomes are underground stems that grow horizontally and can produce new shoots and roots at various points along their length. This method of propagation allows bamboo to spread rapidly and form dense stands, which is characteristic of many species within the bamboo family.

In contrast, the other plants mentioned do not primarily rely on rhizomes for reproduction. Maple and pine trees typically reproduce through seeds, while sunflowers are annual plants that grow from seeds each year. Therefore, bamboo's unique ability to propagate via rhizomes makes it a standout example of vegetative reproduction in the plant kingdom.
