unlikely that even one person alive today knows who were the first people to notice all sorts of differences between plants and learned how to use their unique properties.Nobody, of course, will not name names of these ancient scholars, began to carry out such a deal nebhodimo humanity, the classification of plants.

first timid attempts to classify plants based only on the outside of the similarity of the materials.That is why very often the results were wrong.However, a deeper study of samples of plants, scientists have obtained new evidence, significantly advancing the study of flora.

Modern classification of plants, like most classifications of living organisms, is based on the well known theory of Darwin.It is a kind of family tree that has many branches.Natural proof of the correctness of this theory are the various paleontological finds.Analysis of the structure of ancient extinct plants and its comparison with modern specimens allow us to judge the origin of species and determining the antiquity of modern plants.The result of these studies, it is the union of a group of plants having a common "ancestor".During these experiments Botany carefully trace the evolutionary path of each sample and classify it.

can be divided fauna at higher and lower plants.Lower are algae and lichens, and higher - it mosses, gymnosperms, ferns and flowering plants.Accordingly, these categories are divided into various departments.

biggest department can be called angiosperms, or flowering plants, which includes trees, shrubs, wild and cultivated organisms.It should be noted that they are all significantly different from each other in shape and size, and life expectancy, and many other properties.It is in order to safely navigate in this riot of wildlife and has created a classification of flowering plants.It has brought together a huge number of families, creating groups and subgroups, such as species, genus, order, class and division.These groups were created based on the characteristics of the structure, methods of community development and reproduction of plants.

suffered a big change classification of plants in 1789.The book, written by the famous botanist Antoine Laurent Jussieu named "Genera plant located to the natural order," Section Department of flowering to 15 classes, within which there were about 100 "natural order."This work has brought world-famous French botanist, and most of the names invented by them are today.

some wildlife enthusiasts are not engaged seriously this is quite a complex science, as botany, however, like to breed houseplants.That house "scientists" could be useful classification of indoor plants, which divides this section into three groups: plants of moderate lighting, shade-tolerant and light-loving.

The first group includes virtually all known plants. Citrus, hydrangeas, primrosesand begonias thrive in moderate light.

second group - ferns, ivy, room vines and boxwood plants, rather quietly survive in a shady corner of the garden.

third group - children of the sun, cactus, eucalyptus and Coleus, plants that are not of their own lives without the gentle rays of the sun and quickly dying from a lack of lighting.

not essential classification of plants for lovers of lush greenery and natural beauty of the house. The main thing for them - a timely fertilizing, watering, change the soil and sufficientcoverage of their favorites.After all, instead of a plant bring comfort and an atmosphere of peace, and only to them subservient charm wildlife
