The whole nature of our planet is divided into two huge kingdoms - flora and fauna. What are plants? These are organisms that develop in a static position and receive food from inanimate nature. They feed on water, minerals and sunlight, which they convert into organic compounds during photosynthesis.
What are plants in terms of varieties and mode of nutrition? 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 also lower ones, which include bacteria and unicellular algae. They also receive food 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 prepared, so there are many parasitic ones among them. However, some varieties of higher representatives of the flora also do not synthesize organic compounds. They're just likeand animals, try to get them ready-made. This variety is called carnivorous 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 propagation method? According to this classification, they are divided into trees, shrubs, herbs. Plants reproduce in the following ways: vegetatively, with the help of processes, rhizomes, mustaches; trees are characterized by gymnosperms; the most complex, but the most beautiful - flower. Thanks to the emergence of this method of reproduction, nature has acquired a huge variety of shapes and colors.
What are plants in terms of their uses? Here there is a division into wild, cultural, agricultural, decorative, domestic. Also allocate more technical, weed, 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 intervention, in forests, meadows, steppes, and so on), and cultivated - (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 contains tens of thousands of titles. This huge diversity allows the creation of new varieties and even species.
Until recently, domestic representatives of the flora were not so diverse, untildid not begin to adapt exotic plants. As it turned out, quite acceptable conditions can be created for them at home. It's one thing when exotics were grown in greenhouses, new specimens were received, and from there they got into people's apartments. There are certain guarantees here that these plants are not dangerous, they cannot be poisoned, and they will not serve as an allergen. Fans have the majority of such indoor flowers. But now the business is widespread, when specimens are brought from the bowels of the jungle, which are sold as exclusive. And people buy without thinking about the consequences. And it should. Because demand determines supply, and while people seek to acquire unusual plants, species are being damaged, and human he alth too.
