The blue whale

Blue whale with a length of 30 meters to 33 meters and weighs 180 tons to 250 tons and can reach speeds up to 50 kilometers per hour

Blue whale up capacity to 1,000 horsepower and devoured about 4,100 kilograms of food per day

Blue Whale care about the length of up to about 180 cm and weight of the heart of the Blue Whale 450 kg, equivalent to any size car, so much so that the man can swim in the veins

Blue Whale Zaanafth equivalent to the size of the wings of a plane Mtostahibdo evolution of modern botany during the Renaissance, a period spanning three hundred years of European history began in the fourth century AD. And stimulated European discoveries of the world, during this period, largely the process of studying plant science and other sciences. And pioneer explorers discovered several new species of plants they brought to the students for examination and identification.

And increased trade, demand for all types of plant products such as food, fiber, medicines, dyes increased. Huge gardens which contained many of the new plants have been planned. As a result of excess numbers of new plants and the facts that have been discovered from those plants, legacy systems have proven in the naming and classification of plants it is inadequate.

Line morphology Plant tremendous strides during the seventeenth century after the appearance of the compound microscope. It was one of the first scientists, who observed the exact composition of the plants, the world Marcello Malpighi of Italy and Alanklyzaan Robert Hooke, and Nhmaa Gro. In the seventeenth century began research in physiology work done by Jean Baptista van Helmont Flemish physician and chemist, who scored his observations on how the plant for growth.

During the mid-eighteenth century, the world of natural history Swede Carl Linnaeus developed a system for naming plants, it has become acceptable in the end as a standard for classification. Use Linnaeus bilateral label or name duplication, and where the distinguished name of each plant consists of two parts. This system has been modified and expanded to the modern system of classification of the user now. This is Linnaeus founder of modern botany. Make Linnaeus Division followed, down from largest to smallest, then the community Valrtbh sex Valenua.

Flourished study botany environment of research conducted on the geographical distribution of plants. The world of natural history and geographical German Alexander von Humboldt has developed a map of the distribution of plants in the series during his travels everywhere in the world, during the late eighteenth century and early nineteenth century.

The research conducted by the Austrian botanist Gregor Mendel in the second half of the nineteenth century a major impact on the study of botany and other fields of science. The experiments are based on breeding pea plants, the basic laws of heredity.

In the twentieth century the latest Engaged scientists with the knowledge of plant genetics and molecular biology major discoveries. Within the research that has the maize plant, for example, found that there are certain genes can move from one place to another within the chromosomes of cells. The record of this discovery, announced in 1951, a great addition to the concept of how the inheritance of plants and other organisms for genetic traits.
