An offset is a form of vegetative propagation; which aquatic plant is listed as an offset example?

• A. Pistia
• B. Eichhornia
• C. Cucumber
• D. Banana

Answer: (A)

Offsets are a form of vegetative propagation where a small plantlet forms at the base of the parent and can detach to grow independently. In aquatic environments, Pistia (water lettuce) routinely produces these offsets—little rosettes that bud off from the parent and can separate to become new, clone plants. This makes Pistia a classic example of an offset. The other options don’t illustrate offsets in the same way: water hyacinth mainly spreads through stolons that give rise to new plants, while cucumber and banana propagate by seeds or other structures like runners, suckers, or rhizomes, not by offsets.
