Prop roots are the modified aerial adventitious roots of corn that enable the root system to anchor.

Explanation:

Prop roots are the last roots to develop. They appear when the corn plant presents at least ten real leaves, originating from the first two aerial knots and directing to the ground.  These are thick, pulpy, and vigorous, and penetrate the ground up to 15 cm deep. Their principal function is to support, giving the plant a better anchor. They can also participate in water and nutrients absorption, but this is not their primary function.

sexual reproduction produces offspring with novel combinations of genes. species that reproduce sexually must maintain two different types of individuals, males and females, which can limit the ability to colonize new habitats as both sexes must be present.
