What is a plant is a whole kingdom
The whole nature of our planet is divided into two hugekingdoms are flora and fauna. What are plants? These are organisms that develop in a static position and are fed from inanimate nature. The source of food for them are water, minerals and sunlight, which they convert into organic compounds in the process of photosynthesis.
What is a plant in terms of varietiesand method of nutrition? So called the body, consisting of the 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 receive the necessary substances already prepared, so there are many parasites among them. However, some species of higher representatives of the flora also do not synthesize organic compounds. They, just like animals, try to get them ready. This species is called predator plants. They produce enzymes that can digest biological food, so do not disdain insects and other small animals.
What are plants in terms of appearance andmethod of reproduction? According to this classification, they are divided into tree, shrub, grass. The plants reproduce in the following ways: vegetative, with the help of shoots, rhizomes, mustaches; the trees are characterized by gymnosperms; the most complex, but the most beautiful - the flower. Thanks to the appearance of such a method of reproduction, nature has acquired a huge variety of forms and colors.
What are plants in terms of their application? Here there is a division into wild-growing, cultural, agricultural, decorative, domestic. Also, there are also technical, weedy, medicinal, greenhouse. By the same principle, it is possible to decompose all plants according to different criteria. The two main groups of plants are wild (grow without human participation, in forests, meadows, steppes, etc.), and cultural ones (those that are grown by humans, they were once chosen from the wild and selected). Cultural, in turn, are divided into agricultural, technical, greenhouse, ornamental and domestic plants. The catalog includes tens of thousands of titles. This huge variety allows creating new varieties and even species.
Until recently, home representatives of the florawere not so diverse, until the exotic plants began to adapt. Home for them, as it turned out, you can create quite acceptable conditions. It's one thing when exotics were grown in greenhouses, they received new copies, and from there they got into people's apartments. There are certain guarantees that these plants are not dangerous, they can not be poisoned, and they do not serve as an allergen. There are a lot of such flowers in the room. But now business is widespread, when from the bowels of the jungle brought copies that are sold as exclusive. And people buy without thinking about the consequences. But it should be. Because demand determines the supply, and while people tend to acquire unusual plants, damage to biological species, and human health, too.
