Duckweed Care Guide – Planting, Growing, and Propagation
Aquatic plants are plants that have adapted to living in aquatic environments saltwater or freshwater. They are also referred to as hydrophytes or macrophytes to distinguish them from algae and other microphytes.
A macrophyte is a plant that grows in or near water and is either emergent, submergent, or floating. In lakes and rivers macrophytes provide cover for fish , substrate for aquatic invertebrates , produce oxygen , and act as food for some fish and wildlife. Macrophytes are primary producers and are the basis of the food web for many organisms.
Excess sediment will settle into the benthos aided by the reduction of flow rates caused by the presence of plant stems, leaves and roots. Some plants have the capability of absorbing pollutants into their tissue. Aquatic plants require special adaptations for living submerged in water , or at the water's surface. The most common adaptation is the presence of lightweight internal packing cells, aerenchyma , but floating leaves and finely dissected leaves are also common.
They are therefore a common component of wetlands. Many small aquatic animals use plants such as duckweed for a home, or for protection from predators. Some other familiar examples of aquatic plants might include floating heart , water lily , lotus , and water hyacinth. The principal factor controlling the distribution of aquatic plants is the depth and duration of flooding.
However, other factors may also control their distribution, abundance, and growth form, including nutrients, disturbance from waves, grazing, and salinity. Aquatic plants have adapted to live in either freshwater or saltwater. Aquatic vascular plants have originated on multiple occasions in different plant families;   they can be ferns or angiosperms including both monocots and dicots.
The only angiosperms capable of growing completely submerged in seawater are the seagrasses. An aquatic origin of angiosperms is supported by the evidence that several of the earliest known fossil angiosperms were aquatic.
Although most aquatic plants can reproduce by flowering and setting seeds, many have also evolved to have extensive asexual reproduction by means of rhizomes , turions , and fragments in general. Due to their underwater environment, aquatic plants have limited access to carbon and experience reduced light levels.
DBLs are the main factor responsible for the lack of carbon fixation in aquatic plants. In floating aquatic plants, the leaves have evolved to only have stomata on the top surface due to their non-submerged state. Due to their aquatic surroundings, the plants are not at risk of losing water through the stomata and therefore face no risk of dehydration. Due to their environment, aquatic plants experience buoyancy which counteracts their weight. Gravitropism, along with phototropism and hydrotropism, are traits believed to have evolved during the transition from an aquatic to terrestrial habitat.
There have been multiple studies regarding the physiological changes that terrestrial plants undergo when submerged due to flooding. When submerged in an aquatic environment, new leaf growth from terrestrial plants has been found to have thinner leaves and thinner cell walls than the leaves on the plant that grew while above water, along with oxygen levels being higher in the portion of the plant grown underwater versus the sections that grew in their terrestrial environment.
An emergent plant is one which grows in water but pierces the surface so that it is partially exposed to air. Collectively, such plants are emergent vegetation.
This habit may have developed because the leaves can photosynthesis more efficiently in air and competition from submerged plants but often, the main aerial feature is the flower and the related reproductive process. The emergent habit permits pollination by wind or by flying insects. There are many species of emergent plants, among them, the reed Phragmites , Cyperus papyrus , Typha species, flowering rush and wild rice species.
Some species, such as purple loosestrife , may grow in water as emergent plants but they are capable of flourishing in fens or simply in damp ground. Submerged macrophytes completely grow under water with roots attached to the substrate e. Myriophyllum spicatum or without any root system e. Ceratophyllum demersum. Helophytes are plants that grows in a marsh , partly submerged in water, so that it regrows from buds below the water surface.
Examples include stands of Equisetum fluviatile , Glyceria maxima , Hippuris vulgaris , Sagittaria , Carex , Schoenoplectus , Sparganium , Acorus , yellow flag Iris pseudacorus , Typha and Phragmites australis.
Floating-leaved macrophytes have root systems attached to the substrate or bottom of the body of water and with leaves that float on the water surface. Common floating leaved macrophytes are water lilies family Nymphaeaceae , pondweeds family Potamogetonaceae. Free-floating macrophytes are aquatic plants that are found suspended on water surface with their root not attached to substrate, sediment, or bottom of the water body.
They are easily blown by air and provide breeding ground for mosquitoes. Example include Pistia spp. The many possible classifications of aquatic plants are based upon morphology. Macrophytes perform many ecosystem functions in aquatic ecosystems and provide services to human society. One of the important functions performed by macrophyte is uptake of dissolve nutrients N and P from water.
Habitat complexity provided by macrophytes tends to increase diversity and density of both fish and invertebrates. Some aquatic plants are used by humans as a food source. Examples include wild rice Zizania , water caltrop Trapa natans , Chinese water chestnut Eleocharis dulcis , Indian lotus Nelumbo nucifera , water spinach Ipomoea aquatica , and watercress Rorippa nasturtium-aquaticum. A decline in a macrophyte community may indicate water quality problems and changes in the ecological status of the water body.
Such problems may be the result of excessive turbidity , herbicides , or salination. Conversely, overly high nutrient levels may create an overabundance of macrophytes, which may in turn interfere with lake processing. Phytochemical and pharmacological researches suggest that freshwater macrophytes, such as Centella asiatica , Nelumbo nucifera , Nasturtium officinale , Ipomoea aquatica and Ludwigia adscendens , are promising sources of anticancer and antioxidative natural products.
Hot water extracts of the stem and root of Ludwigia adscendens , as well as those of the fruit, leaf and stem of Monochoria hastata were found to have lipoxygenase inhibitory activity. Hot water extract prepared from the leaf of Ludwigia adscendens exhibits alpha-glucosidase inhibitory activity more potent than that of acarbose.

Duckweed Aquarium Plant: How to Grow and Care Guide
However, the downsides are that duckweed has a tendency to take advantage of the ammonia in a fish tank and grow TOO fast, clogging filter intakes, and sometimes introducing parasites and snails into an otherwise balanced aquatic system. You CAN add duckweed to fish aquariums if you are willing to do the following:. Disinfect your duckweed if you are concerned about its source. I raise mine outdoors and have not had an opportunity yet to do this, but there are sites that describe how to use a weak solution of bleach or potassium permanganate to kill parasites and snails. See Aquaculture discussion.
Maintaining a Planted Aquarium
Many ponds have more than one type of aquatic plant, and care must be taken to identify all the aquatic plants inhabiting the pond. Some pond plants may be beneficial to local or migratory wildlife, and therefore, may want to be encouraged or at least not eliminated. Click on whichever group of aquatic plants that you feel your specimen may belong to and work through the examples until you find it. Algae are very primitive plants. Some algae are microscopic planktonic algae.
In an aquarium or water garden, floating plants are essentially a boon to the just use the speediest growing floating plants like hornwort and duckweed.
There are many plants that grow in water. Some of these plants can be found in the water, while others have roots that rest on a substrate, and the leaves project above the surface. There are some aquatic plants that you can use as fish food, such as duckweed or water lettuce. What are the best plants that grow in water?
Home » Floating Aquarium Plants. Living plants can bring a new dynamic to your fish tank. Floating aquarium plants not only keep water healthy but also provide protection and shelter for shy fish. They are also a great way of natural beauty. Many fish-keepers are enthusiastic to grow plants in their aquarium. Because some plants need extra lighting and others require a high nutrient intake.
We aimed to determine the effects of nutrient availability on the growth rate and carrying capacity of Lemna minor.

I had always been really interested in gardening, particularly in aquatic and floating plants. So when I finally had my own space to dabble in growing floating plants, I took a shot at it, only to make several rookie mistakes and my plants withered. So how can we take care of floating plants? Ensure that the plants are aided in aeration by filtration systems, and that the floating direction is controlled.
