The whole nature of our planet is divided into two huge kingdoms - this is flora and fauna. What are plants? These are organisms that develop in a static position and receive food from inanimate nature. The source of food for them is water, minerals and sunlight, which they convert into organic compounds during photosynthesis.
What are plants in terms of variety and diet? This is the name of an organism consisting of a root, stem, branches and leaves. These are the highest representatives of the flora. There are lower ones, which include bacteria and unicellular algae. They also get nutrition from the environment, but it enters the cell through its entire surface. As for bacteria living in places without access to sunlight, the process of photosynthesis does not occur in them; they can get the necessary substances already ready, so many of them are parasitic. However, some varieties of higher flora representatives also do not synthesize organic compounds. They, like animals, try to get them ready-made. This species is called predator plants. They produce enzymes that can digest biological food, so they do not disdain insects and other small animals.
What are plants in terms of appearance and method of propagation? According to this classification, they are divided into tree-like, shrubs, grasses. Plants reproduce in the following ways: vegetative, using processes, rhizomes, mustaches; gymnosperms are characteristic of trees; the most complex, but the most beautiful is flowery. Thanks to the emergence of such a method of propagation, nature has acquired a huge variety of shapes and colors.
What are plants in terms of their application? Here there is a division into wild, cultural, agricultural, decorative, domestic. Also isolated are technical, weedy, medicinal, greenhouse. By the same principle, all plants can be decomposed according to different criteria. The two main groups of plants are wild (grow without human participation, in forests, meadows, steppes, and so on), and cultural - (those that people grow, they were once selected from the wild and selected). Cultural, in turn, are divided into agricultural, technical, greenhouse, ornamental and domestic plants. The catalog has tens of thousands of names. This huge variety allows you to create new varieties and even species.
Until recently, domestic representatives of the flora were not so diverse until they began to adapt exotic plants. Houses for them, as it turned out, you can create quite acceptable conditions. It is one thing when exotics were grown in greenhouses, new specimens were obtained, and from there they ended up in people's apartments. There are certain guarantees that these plants are not dangerous, they can not be poisoned, and they will not serve as an allergen. Most of such indoor flowers are among amateurs. But now business is widespread when copies are brought from the bowels of the jungle that are sold as exclusive. And people buy without thinking about the consequences. And it would be necessary. Because demand determines supply, and as long as people strive to acquire unusual plants, damage is caused to biological species, and human health too.
