Corn even has little prop roots at the base of the stalk to buttress it.

If, by accident, the underground roots die off, the plant relies entirely on these air and prop roots for support and food.

Such roots become supporting or prop roots and are particularly conspicuous in several stout tall grasses such as Andropogon Sorghum, Zea Mays and Pennisetum typhoideum.

The strong prop roots are generally of the same diameter throughout, though sometimes they thicken at the ends.

Another very prominent feature of pandans is the presence of air or prop roots which grow from the stem above the ground and are helpful to the plant in various ways.
