Final answer:
The gumamela or hibiscus plant does not reproduce sexually, but rather through vegetative propagation.
Step-by-step explanation:
Out of the options given, the plant that does not reproduce sexually is the gumamela or hibiscus. Unlike most plants, which reproduce sexually through the fusion of male and female gametes, gumamela reproduces asexually through a process called vegetative propagation. This involves the growth of new individuals from vegetative parts of the parent plant, such as stems or leaves, without the involvement of flowers or seeds.
