1. The plants of an aquarium

The world of aquarium plants is a part of the world of water plants. These have appeared in the Planetary Ocean a few billion years ago within the intrinsic and characteristic process of the living matter, of biological evolution. By dividing the classes and subclasses of plants and animals according to the developing environments, S.A. Zernov considers that 75% come from water, respectively 69% from sea, 6% from soft water basins and only 25% from land. The relative equability of the aquatic environment has favored a lower diversification on species- about 1.500.000 species.

By tracing the way of organization of water life, we observe that it depends on factors such as: physical-chemical peculiarities of water, the nature of the substrate, the altitude and the chemical elements, in one word, biotope factors.

Morphological and biological peculiarities of aquarium plants:

Superior water plants or cormophyte (from the Greek CORMOS-log, shank; plants with a differentiated body in root, shank and leafage) group the most evolved plants; they represent the favorite group of aquarists. Their ancestor is found in the algae world of over 50 million years ago. It has appeared on land and diversified in over 300.000 actual species, an amount almost double than the one of the inferior plants among which they have detaches- 175.000 species. Then readjusted to the aquatic environment, the water plants of today have suffered some morphological and anatomical alterations. Thereby, these secondary adaptations have solicited the reduction of some tissues (mechanical, of protection, assimilation) or processing new tasks (air depositing). Some plants are strictly aquatic, others present adaptive alterations to the aerial environment and even to the terrestrial one.

The attachment and nutrition member in the substrate is the root. The main or central root persists in few plants. It dies early or remains undeveloped, her tasks being taken over by secondary and adventitious roots, which appear in nodes. Their universality will form the root system. The roots have a cylindrical shape, being slightly thickened, or filamentous. The root system extracts form the substrate the mineral and organic substances, necessary to the plant for growth and development. For this reason, it distributes in the soil according to the specific of the plant but, especially, according to the nature of the subsoil. A dense substrate (clayey-sandy or argillaceous), won’t allow the growth of the roots more than the surface, being exposed to putrefaction and, in general, to a weak superficial protraction. A light soil (gritty or sandy-clayey), constantly rummaged, and allows the growth of the roots in depth and at surface, favoring a better contact with the environment, a more active exchange of gas (a respiration) and a more intense absorption of the necessary substances. Usually, the roots are white, but they can also be colored from a pale yellow to a dark brown. The roots can express the state of health of the plants, but also of the environment they live in. in some species, the roots are underdeveloped, and in others, they are missing. Comparative with terrestrial plants, to the water ones, the root system is much more underdeveloped because the plant absorbs the nutriment through the entire surface of the body. The leafage of water plants are composed of limb, sheath and petiole as the leafage of the plants of which they come- terrestrial plants. If we observe a swamp plant, that has submerged, emerged leafage (buoyant) and aery leafage, we notice a visible differentiation at the same organ, which is nothing else than the adaptation to the two vital environments that are so different-water and air. The submerged leafage, surrounded by water, are supported by liquid and, because of the large quantity of gas from the tissues, they are drawn to the surface.

The supporting tissues (mechanical) appeared and grown in the terrestrial phase, become useless for this function. They will reduce and, from a peripheral position, they will take the central place in the stem (or in the leaf), which will prevent the rupture of the plant powerfully drawn to the surface. All the adaptations of the terrestrial plants in order to prevent a great loss of water (by perspiration) are superfluous to the submerged leafage (or plants). If the terrestrial leafage seek to reduce to a minimum their surface reported to volume, but with a maximum capacity of assimilation, aquatic leafage aspire to the realization of a surface as large as possible (3-4 times higher than terrestrial leafage).

That is way submerged leafage are very thin, with a larger surface as against volume and with a greater possibility of necessary substances to life exchange. Also, the large difference between the concentration of the oxygen and carbon dioxide from air and water has led to a series of other alterations. In water,
