(d) seed

Show Answer

Answer : b

Hints & Solutions

(b) Each pseudostem produces a single bunch of bananas, before dying and are replaced by a new pseudostem. The base of the plant is a rhizome (known as a corm). Corms are perennial, with a productive lifespan of 15 years or more. Cultivated bananas are parthenocarpic, which makes them sterile and unable to produce viable seeds. Lacking seeds, another form of propagation is required. This involves removing and transplanting part of the underground stem (called a corm). Usually this is done by carefully removing a sucker with some roots intact.
