Duckweed
Duckweed reproduces by two methods, budding and seeding.
Seeding: At the beginning of winter, seeds are created from the old flower pods and sink to the bottom of water for germination. During this process, the seeds become turions and when winter ends they rise to the surface.
Budding: The oldest fronds of the plant develop pouches on their stems, these contain new buds. In time the buds split through the pouches. They then sink down to the bottom of the pond until spring when they float back up to the top as adult plants.

Salamander
Male and female salamanders look the same. Their genders aren't easy to identify, particularly because their genitals are not visible. The gender differences are most apparent during breeding
season. For example, some males have visible hairs around the cloaca when they
are ready to mate. in the wild, breeding season occurs once, typically toward
the end of summer. If the cloaca of your salamander becomes enlarged once a
year, it is probably a male.
Salamanders lay large quatities of eggs suspended in a gel type liquid in a large mass. These masses are then laid in the water, the salamanders are born with gills and are able to survive. They Fertilize by “Sperm packets” deposited by male in water and taken up by female for internal fertilization.
From fertilization, salamanders protect the egg packet from preditors.
