The term ‘botanical’ is derived from the adjective ‘botanic’ which is again derived from the Greek word ‘boten’. A person who studies ‘botany’ is called a ‘botanist’.
Botany is one of the oldest natural sciences in the world. Initially, botany included all plant-like organisms such as algae, lichens, ferns, fungi, mosses, along with true plants. Later it was observed that bacteria, algae and fungi belong to a separate kingdom

History of Botany
Plants are the main source of life on earth. They provide us with food, oxygen and various raw materials for various industrial and domestic purposes. This is why humans have always been interested in plants since ancient times.
The Greek scholar Theophrastus was one of the world’s earliest botanists. He is also known as the “Father of Botany” because of his voluminous writings on plants. One of his books called “Inquiries into Plants” classified plants based on geographic range, size, use, and growth patterns. Another work entitled “On the Causes of Plants” explained the economics of growing plants

Dioscorides was another Greek physician from 90-40 AD who wrote an encyclopedia on herbal medicine called “De Materia Medica”. This book was used as an important medicinal guidebook for more than 1500 years until the invention of the compound microscope.
The invention of the compound microscope by Robert Hooke in 1665 marked the advancement of scientific knowledge in the field of botany. He helped in the study of plant anatomy and physiology. The discovery of chlorophyll helped to understand the process of photosynthesis. Gregor Mendel studied genetic inheritance in plants through experiments on pea plants.
With the advent of biotechnology and genetic engineering, scientists have been able to better understand the structure of plants and have devised better ways to improve crop yield and crop health.

Branches of Botany
Botany is divide into several branches:
Plant Pathology
It is the study of the organisms and environmental conditions responsible for causing disease in plants, the mechanisms by which disease occurs, and methods of controlling plant diseases.
Plant Ecology
Plant ecology studies the distribution of plants, how environmental factors affect plants, and the interactions between plants and other organisms

Palaeobotany
It is the branch of botany that deals with the recovery and identification of plant fossils, thus, studying the evolutionary history of plants.
Archaeology

1)Botany deals with the study of different types of plants, their uses and properties to influence the fields of science, medicine and cosmetics.
2)Botany is key to the development of biofuels such as biomass and methane gas that are use as alternatives to fossil fuels.
3)Botany is important in the field of economic production as it involves the study of crops and ideal growing techniques that help farmers increase crop yields.
The study of plants is also important in environmental conservation. Botanists catalog the different types of plants on Earth and can understand when plant populations begin to decline.
