Aquatic plants require special adaptations for prolonged inundation in water, and for floating at the water surface. The most common adaptation is the presence of lightweight internal packing cells, aerenchyma , but floating leaves and finely dissected leaves are also common.
Limnobium laevigatum is a floating aquatic plant, which can be mistaken for water hyacinth (Eichornia crassipes) due to their superficial similarity.Juvenile plants grow in rosettes of floating leaves that lie prostrate upon the water surface, a distinguishing character of the juvenile plant is the presence of spongy aerenchyma tissue upon the abaxial surface (underside) of the leaf.
When referring to plants, the term describes land plants whose roots have adapted well to tolerate regular, prolonged submersion in water, as well as emergent and (occasionally) floating-leaved aquatic plants that are only partially immersed in water. Examples of semi-aquatic animals and plants are given below.
Nymphoides, or floatingheart, [1] is a genus of aquatic flowering plants in the family Menyanthaceae. The genus name refers to their resemblance to the water lily Nymphaea. Nymphoides are aquatic plants with submerged roots and floating leaves that hold the small flowers above the water surface.
Close-up of floating aquatic plants: Spirodela polyrrhiza and Wolffia globosa; the very tiny Wolffia plants are under 2 millimetres (0.079 in) long. Wolffia is a genus of aquatic plants with a cosmopolitan distribution. [1] They include the smallest flowering plants on Earth. [2] Commonly called watermeal or rootless duckweed, [3] [4] these ...
Ludwigia helminthorrhiza grows from the water's edge into the water and along the stem and roots develops 1 - 1.2 cm long white rootlets which function as floating bodies to keep the main plant floating on the surface. At each nodus, the plant may develop roots
It floats on the surface of the water, its roots hanging submersed beneath floating leaves. The leaves can measure 2 – 15 cm long and are light green, with parallel venations and wavy margins. [8] The surface of the leaves is covered in short, white hairs which form basket-like structures that can trap air bubbles and increase the plant's ...
Banana plants should have a third of the larger banana shaped roots buried in the gravel. The plant will also put out normal shaped roots. The lowermost leaves grow 15–46 cm tall and frequently the plant will produce a floating lily-leaf at the surface. Given optimal conditions, this plant will commonly flower in the tank.
