whole nature of our planet is divided into two great kingdoms - is the flora and fauna.What is a plant?This organism that evolves in a static position and draw power from inanimate nature.The source of food for them are water, minerals and sunlight, which are in the process of photosynthesis are converted into organic compounds.
What plants in terms of types and methods of supply?So called body, consisting of a root, stem, branches and leaves.This is the highest representatives of the flora.There are also lower, which include bacteria and unicellular algae.Meals are also obtained from the environment, but it enters the cell through the entire surface thereof.With regard to bacteria living in areas without access to sunlight, in which the process of photosynthesis occurs;they can receive the necessary material ready-made, so many of them are parasitic.However, some species of higher flora also do not synthesize organic compounds.They, as well as the animal trying to get them off the shelf.This variety is called plant predators.They produce enzymes capable of digesting the biological food, so do not disdain insects and other small animals.
What is a plant from the point of view of appearance and method of reproduction?According to this classification, they are divided on the tree, shrubs, herbs.Propagate plants in the following ways: vegetatively via shoots, rhizomes, mustache;for trees typical of gymnosperms;the most difficult, but the most beautiful - flowering.The emergence of this method of reproduction has acquired the nature of a huge variety of shapes and colors.
What plants in terms of their use?There is division in the wild, cultural, agricultural, ornamental, home.Also allocate more technical, weed, drugs, greenhouse.The same principle can be expanded all the plants on different criteria.The two main groups of plants - wild (grow without human intervention, forests, grasslands, steppes, and so on), and cultural - (those grown men they once were selected from the wild and were selected).Culture, in turn, are divided into agricultural, technical, greenhouse, ornamental and house plants.Product has tens of thousands of titles.This allows you to create a huge variety of new varieties and even species.
Until recently, the domestic flora were not so diverse, have not yet become adapted exotic plants.Houses for them, as it turned out, it is possible to create acceptable conditions.It's one thing when exotics grown in greenhouses have new items, and from there they were in the apartment people.There is a certain guarantee that these plants are not dangerous, they can not be poisoned and they do not serve as an allergen.Such indoor plants have the majority of fans.But now widespread business when from the depths of the jungle brought copies 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 tend to buy unusual plants, causes damage to species, and human health too.
