What are aquatic plants?

Aquatic plants live in water

Our aquatic plants They are those that, unlike terrestrial ones, are adapted to environments with high humidity. There are some that even live in water, such as in lakes or rivers. They are very interesting to have in a garden pond, as it gives them a new, very elegant appearance.

These are plants that we usually see very often in nurseries and homes, since they are very easy to care for and maintain. Let's see what aquatic plants are.

What is the definition of aquatic plants?

The mangrove is an aquatic tree

Our protagonists, also known as hydrophytes or hygrophytes, are plants that are adapted to live in humid or aquatic environments. They can be algae, or vascular plants, pteridophytes and angiosperms (the latter with showy flowers). Normally they are strongly rooted in the silt that is found at the bottom of the waters, but there are others that remain floating on the surface.

Generally live in freshwater environmentslike lakes, rivers or ponds, but we can also find them in salt water environments, where the mangroves which are trees whose roots resist the high concentration of salts in the intertidal zone near the mouth of fresh water courses in tropical regions.

How are they classified?

Depending on where they are found, three classes of aquatic plants are distinguished:

  • Floating plants: are those that, as their name suggests, float on the surface. Its roots may or may not anchor to the bottom. Examples: salvinia natans, Nymphaea or Phyllantus fluitans.
  • Submerged plants: are those that live under water, either anchoring to the bottom or not. Examples: Cabomba australis (aquatic nettle), Egeria densa o Vallisneria spiralis.
  • Emerging plantsThese are the ones that take root at the bottom, keeping leaves, flowers and stems in the open air. Examples: Cyperus papyrus (papyrus), Juncus (reed), or the Oryza sativa (rice).

Types of aquatic plants
