Aquatic plants live in both the benthic and pelagic zones, and can be grouped according to their manner of growth: ⑴ emergent = rooted in the substrate, but with leaves and flowers extending into the air; ⑵ floating-leaved = rooted in the substrate, but with floating leaves; ⑶ submersed = growing beneath the surface; ⑷ free-floating ...
Pond life is an umbrella term for all life forms found in ponds. Although there is considerable overlap with the species lists for small lakes and even slow-flowing rivers, pond life includes some species not found elsewhere, and as a biome it represents a unique assemblage of species.
Pontederia cordata, common name pickerelweed or pickerel weed (), is a monocotyledonous aquatic plant native to the Americas. It grows in a variety of wetlands, including pond and lake margins across an extremely large range from eastern Canada south to Argentina.
These plants are placed in a pond or container usually 1–2 ft (0.30–0.61 m) below the water surface. Some of these plants act as oxygenators as they create oxygen for any animals which live in a pond. Examples of submerged plants are: Hornwort (Ceratophyllum demersum) Water-lilies (Nymphaeaceae) Lotus (Nelumbo spp.) Featherfoil (Hottonia ...

The technical distinction between a pond and a lake has not been universally standardized. Limnologists and freshwater biologists have proposed formal definitions for pond, in part to include 'bodies of water where light penetrates to the bottom of the waterbody', 'bodies of water shallow enough for rooted water plants to grow throughout', and 'bodies of water which lack wave action on the ...
