Biology is the subject that elucidates our knowledge of different life forms. It is a major branch of science that makes us able to see life beyond our normal vision. When we talk about life forms; most of us observe things taking place in our surroundings like birds flying, people communicating, plants having colorful flowers and fruits. But only a Biologist can draw out the reasons and meaning of every activity, gesture, and moment.
Biology conducts study from a minute cell to the entire organism. It provides answers about the immune system of the living body and the functioning of every organ. Whether it’s adaptation in plants or products of animals; all the answers about life can be acquired from the study of this subject. Presently, the growing research and globalization have helped researchers to investigate the most talked and discussed topic i.e. Human genome. Hence, answers to different forms of life can be found under Biological study.
Similar to the other fields of Science; biological information’s are also based on Observations, Hypothesis, experiments and results. Since Biology is real science, no hypothesis is forwarded or accepted until it is approved by conducting a proper experiment. Hence, this is the reason that years of experiments and findings on varied topics have been stacked in a large volume of Biology book. Today we have answers to most of the questions on the living world. What factors mark the beginning of life? How are living being able to survive in different environments? How does the living system work? Answers to these and many such questions can be acquired from different sections of the Biology textbook.

With the invention of advanced scientific instruments, researchers have step forward for deeper study on living beings and this is the reason that Biology is now termed Modern Biology.
Four main theory of Modern Biology
1. The cell theory
Robert Hook was the first Biologist to discover cells. The cell is the basic entity of life that arises from the pre-existing form. Thus, cell theory explains the working of cells and their function. This credit for formulation of cell theory is given to three well-known scientist Theodor Schwann, Matthias Schleiden and Rudolph Virchow. Though the earlier concept of cell theory focused on the basic information about the cell, the recent concept on cell theory is elaborated by defining the importance of DNA in a cell and the Energy flow system of the cell. Overall, cell theory explains the structure, working, and function of different cells in a living body.
2. Evolution by Natural Selection
Though many scientists and Biologists worked on this theory, it was Charles Darwin who first provided the world some interesting examples to prove the Evolutionary theory of natural selection. The key concept of this theory is that species are produced in large numbers. But environment selects only those species that can survive environmental consequences and possess a heritable trait that serves as an advantage for their survival.
3. Gene Theory
The study conducted by George Mendel on pea plants was the first insight on gene theory. His research gave an answer to the question that “how some traits transfer from one generation to the other”? His experiments and findings concluded that it is gamete that is involved in the transmission of characteristics. Hence, In Gene theory gene is described and proved as a unit of inheritance. After Mendel’s work on pea plants, many other researchers turned up and worked on genes, chromosomes, and DNA. Hence, time and again with new findings and results, changes were made in gene theory.
The word homeostasis was first coined by cannon. Homeostasis means “internal body condition remains constant even if there is a change in the outer environment”. This theory of Biology includes the detailed study of the endocrine system and the nervous system of brain. It comprises pH balance, blood pressure, electrolyte, and many more.

Our online Biology experts have made a list of a few important areas of this field. Some of them are briefly explained below:
1. Anatomy: Anatomy means the study of internal parts of a living body. The study on the anatomical part that can be easily viewed by naked eyes is segmented under gross anatomy and those parts that form the basic organization of a living body are studied under the Histological section. This area of study is important to discover the functioning, composition, and importance of any specific part or organ. Hence, when plant anatomy is studied, it is termed plant anatomy. Likewise, the anatomical study of animals is termed animal anatomy.
2. Cell Biology: Cell is the foundation of any living body. It is the first step for the beginning of life. Though it is minute and cannot be seen by naked eyes, it is made of many important components. Hence, knowledge of cells, their structure, composition and function can be obtained by the study of Cell Biology. Presently, cells are also important to conduct study on different diseases, transplantation of organs, immune system of body and many more. Hence, Cell Signaling, Cell movement, Cell Culture, Cell cycle are some of the important topics dealt under this area of Biology.
3. Molecular Biology: It is the area of biology that elucidates our knowledge of the living organism at a molecular level. It also provides information on the interaction of different systems of a body at the molecular level. Hence, molecular biology is connected with many other fields of Science including Cell Biology, Genetics etc. Some important topics segmented in this field of Biology are Biomolecules, Gene expression, Membrane Biology.
4. Genetics: Genetics include the study of gene, heredity, and variation of an organism. The reason for transmission of trait, genetic disorders, Study on Chromosomes and DNA are sliced in this field of Biology. Presently, with the concept and ideas of this field, people have started modifying animals and plants to obtain maximum benefit. Hence, this field of Biology includes a wide range of topics like genetic engineering, Epigenetics, Molecular genetics, and many more.
5. Microbiology: Microbiology deals with the study of minute organism or smaller organisms that cannot be viewed by our naked eyes. Presently, microorganism are important in different research fields as they are used in designing drugs and studying about viruses including many other pathogens. Hence, subjects like Bacteriology, Viruses, Virology, and Microscopy are dealt with under this area of Biology.
6. Biochemistry: Biochemistry deals with the structures and functions of biomolecules that form the components of the living cell and develops an understanding of how various biological processes in living beings. For the understanding of how cellular structures are made and how cellular structures of living cells work, it is important to understand about the complex biomolecules such as proteins, peptides, amino acids, carbohydrates, glucose, fructose, nucleic acids like Deoxyribose Nucleic Acid DNA and RNA including DNA cloning and DNA sequencing, antioxidants, generation of free radicals, the study of the chemistry of fats and lipids like glycerides and triglycerides. Understanding the structure and functioning of these biomolecules helps to understand cell functions like cell signalling, neurochemistry and Neurology, bioinformatics, genetics, heredity, genomics, evolution, and other life processes like metabolism, nutrition, RNA transcription, respiration, aging and diseases, protein metabolism, muscles and more. Biochemistry is also important to understand drug interactions and diseases like cancer, AIDS, HIV, immunological responses, immune systems and hormonal systems as well as to develop an understanding of agricultural biology, molecular biology, parasitology, pharmacology and oncology (cancer). You will learn how to uncover the molecular processes of life and how this knowledge can be applied in medical science and biotechnology such as sequencing, cloning, protein synthesis, mutations, enzyme reaction, and kinetics, and more. Biochemistry is widely used in areas like Agriculture and horticulture, industries related to biotechnology and pharmaceuticals, genetically modified organisms, Biochemical Intellectual property industries, stem cell research, Medical research, biomedical science research projects as well as advanced biochemistry and biotechnology laws related to intellectual property.
