Why won't you find plant life in the aphotic zone?

In aphotic zones there is less than 1% sunlight since it is very deep in the ocean, most plants wouldn't be able to grow since they wouldn't have the resources.

No sunlight,  up to a kilometre away from the surface, the temperature and pressure becomes too unsuitable organisms to survive. This is a minor factor compared to the lack of light. Hence, we won't find plant in aphotic zone.

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.
