In the 4-th century BC in Greece, there were only a few schools, and none taught science. It was left to philosophers to come up with logical explanations of the world. Aristotle studied under the famous philosopher Plato, who regarded thought or the idea as the basis of all knowledge. Aristotle later decided that theories about the world must be based on the close study and classification of nature. Aristotle catalogued the known species of animals and plants, believing they were made of four elements: earth, water, fire, and air. He also believed that a fifth element, ether, surrounded the Earth.

                                     Scope and importance of botany
1. In biology, plant life can be studied from different perspectives, from the molecular, genetic and biochemical level through organelles, cells, tissues, organs, individuals, plant populations, and communities of plants. At each of these levels a botanist might be concerned with the classification, structure (anatomy and morphology), or function (physiology) of plant life.
2. Historically all living things were grouped as animals or plants, and botany covered all organisms not considered animals. Some organisms once included in the field of botany are no longer considered to belong to the plant kingdom – these include fungi (studied in mycology), lichens (lichenology), bacteria (bacteriology), viruses (virology) and single-celled algae, which are now grouped as part of the Protista. Paleobotanists study also ancient plants in the fossil record. It is believed that early in the Earth's history, the evolution of photosynthetic plants altered the global atmosphere of the earth, changing the ancient atmosphere by oxidation.
3. The study of plants is vital because they are a fundamental part of life on Earth, which generates the oxygen, food, fibres, fuel and medicine that allow humans and other life forms to exist. Through photosynthesis, plants absorb carbon dioxide, a greenhouse gas that in large amounts can affect global climate. Additionally, they prevent soil erosion and are influential in the water cycle. A good understanding of plants is crucial to the future of human societies as it allows us to produce food to feed an expanding population, to understand fundamental life processes, to produce medicine and materials to treat diseases.

Dear Sirs,
We have received your letter of 20th December, this year, and are puzzled by your decision to prolong for only one month guarantee period for the generator which broke down owing to manufacturing defects.
2_______ to Clause 7 of our contract providing for the prolongation of the guarantee period, if the equipment breaks down owing to the defects of the manufacturing plant for the period during which the equipment stood idle.
3_______ that we duly informed you about the breakdown of the generator. Your representatives, however, arrived at the plant after a big delay as a result of which the generator was put into operation only two months after its breakdown.
Moreover we are surprised at your refusal to compensate us fully for the losses caused by the idle time of the generator.
Under our contract the Customer has the right to make a claim if the equipment fails due to the above reasons.
4_______, we would like to resume our talks and to finalize the date of the expiration of the guarantee period and to solve the matter of full compensation of our losses.
Yours faithfully,
Mr Brown
