Question 3
Which of these plants propagates naturally by runners?
The right answer is the one marked above.
Gotu kola. Its stems travel across the surface of the soil, rooting wherever a node touches down.
Banana propagates by suckers, which come up from a buried stem base; Bryophyllum by plantlets on its leaves; turmeric by a rhizome, which is an underground stem. All four are vegetative, but only one runs along the surface.
