It is the brach of science that deals with the composition, structure and properties of substances and its applications to the reactions to form new substances.

Employment Areas for Bachelor of Science [BSc] Chemistry – BSc Chemistry graduates can find a career in Chemistry in the following sectors –
Botany is the scientific study of plants "Plants," to most people, means a wide range of living organisms from the smallest bacteria to the largest living things - the giant sequoia trees. By this definition plants include: algae, fungi, lichens, mosses, ferns, conifers and flowering plants. Today scientists believe bacteria, algae and fungi are in their own distinct kingdoms.
Because the field is so broad, there are many kinds of plant biologists and many different opportunities available. Botanists interested in ecology study interactions of plants with other organisms and the environment. Other field botanists search to find new species or do experiments to discover how plants grow under different conditions. Some botanists study the structure of plants. They may work in the field, concentrating on the pattern of the whole plant. Others use microscopes to study the most detailed fine structure of individual cells. Many botanists do experiments to determine how plants convert simple chemical compounds into more complex chemicals. They may even study how genetic information in DNA controls plant development. Botanists study processes that occur on a time scale ranging from fractions of a second in individual cells to those that unfold over eons of evolutionary time.
New positions in botany are expected to increase at an above-average rate through the turn of the century. Growing world population continues to increase the need for better food supplies. Environmental concerns, such as air, water and soil pollution, will create openings for ecologists in government and industry. The search for new drugs and medicines and useful genes for improving crop plants will continue to create a need for botanical explorers.
Industry is the third major employer of plant biologists. Drug companies, the oil industry, the chemical industry, lumber and paper companies, seed and nursery companies, fruit growers, food companies, fermentation industries (including breweries), biological supply houses and biotechnology firms all hire men and women trained in botany. Recently the first genetically altered food crop, the FlavrSavr(tm) tomato, reached store shelves. This opens a new career field for botanists.
Zoology (also known as animal science) is the branch of biology devoted to the study of animal life. It covers areas ranging from the structure of organisms to the subcellular unit of life. Some zoologists are interested in the biology of particular groups of animals. Zoology is both descriptive and analytical. It can be approached either as basic science or as applied science.
Historically, the study of zoology can be viewed as a series of efforts to analyze and classify animals. The ancient Greek philosopher Aristotle is credited with devising the system of classifying animals that recognized similarities among diverse organisms in the fourth century B.C.E.; he arranged groups of animals according to the mode of reproduction and habitat. Zoology began to emerge as a science in the 12th century and long was dominated by studies of anatomy and efforts at classifying animals. The Swedish botanist Carolus Linnaeus developed a system of nomenclature that still is used today — the binomial system of genus and species — and established as a discipline taxonomy, the science of classification according to a predetermined system.
Zoology today is as diverse as the animal kingdom it studies, broadening its range to include such fields as genetics and biochemistry. It now is considered an interdisciplinary field that applies a great variety of techniques to obtain knowledge of the animal kingdom. For instance, the genetic study of DNA from various animals can provide insights into their evolutionary history. Zoologists who concentrate on the morphology (the study of structure, including muscles, bones, cells, and cellular components) employ many techniques first developed in the biochemistry lab.
Subdisciplines that concentrate on specific divisions of animal life:
The types of jobs zoologists perform also are quite diverse. The zoology undergraduate major is chosen by many students who seek a career in one of the several health care professions (veterinary medicine, medicine, dentistry) or careers in the environmental sciences. Jobs are available in the agricultural, biotechnological/pharmaceutical, and environmental/ecological fields. There are jobs available working outdoors doing fieldwork as well as working in a lab. Career options include positions in government departments, environmental agencies, education (including universities and colleges), and industry (including consulting firms and biomedical companies). Depending on the way the biological sciences are organized at a particular college or university, the student interested in majoring in zoology actually could receive a degree in biology with a concentration in zoology.
