Enzymes. There are 3 main types: Peptidase, Lipase, and amylase :) hope that helps! I'm learning that stuff too :)
Flowering plants produce male and female cells. The male cells are called pollen and the female cells are called ova. When a flowering plant is fertilized, it produces offspring in the form of seeds. However, not all plants reproduce flowers. Simpler plants, like mosses, lack these specialized structures.
I would say pelagic isn't a zone of ponds and lakes. A pelagic zone is more a zone of the sea rather than ponds and lakes.
