The importance of botany

The study of plants is vitally important because all of the food that people and animals eat comes from plants, either directly or indirectly. Except for certain species of bacteria, plants are the only organisms that can make their own food. They do so by the process of photosynthesis. As a result, plants form the case or nature’s food chain the system by which energy is transferred from one organism to another in the form of food. Since the earliest times in human history, people also have used plant as medicine, as material for building, and as a means of beautifying their surroundings, Botany also increases understanding of all forms of through studies of plants, scientists learn how plants, animals, and other organisms interact with one another. They also learn how living things have developed and changed through time. Research by botanists benefits people in a great variety of ways. For example, some botanists study plant genetics to develop new crop plants that are more productive and resistant to pests and diseases. Other botanists use findings in plant ecology to develop ways of im­proving the lumber industry while minimizing harm to the environment still other botanists study fossils of extinct plants to provide clues to the earth’s history and to help geologists searching for oil.
