Every single organism on earth is made from the complex structures of various cell structures that altogether combine to form the various types of tissues and organs. Thus, we can say that all organisms are basically cellular organisms.
Cells are the most important part of our life. They are known to be the structural as well as the functional unit of life and so are the most essential units in our body without which our existence is not possible.
Cell biology, in the academic discipline is the study of cells which is also known as Cellular biology, or Cytology. The study of Cell biology includes the various topics such as
The word cell is derived from the Greek word, “Kytos” meaning “container”. It encloses inside its membrane all the cell organelles which play a very vital role in all the essential life processes occurring inside our body. Thus, cell biology, along with the study of the cell structure also entails the study of all the cell organelles with their functions and the vital roles in the life processes. It also includes the study of the various cell activities that are performed inside these cells and have a great influence on our health, body and life. These activities include the cell interactions, cell signaling, life cycle, cell division (mitosis and meiosis) and finally cell death. The study of all these activities and interactions is extremely important as a minor change in them can result into a notable change in our body. Thus, it gets very essential that we learn in details about their structure and the proper working in our body.
This very basic study of the most basic unit of our life is thus categorized into the various categories based on the type of cells, their similarities and the varied differences. Simply based on the study of the cell and the cellular activities which are included in cellular biology, other fields are also developed which are:
• Genetics
• Biochemistry
• Molecular biology
• Developmental biology
These fields have their basics in cell biology, but simply spread boundlessly due to their complexity and significance. Genetics, deals with the study of the genes and the genetic codes which are the inheritable matters in our body which are transmitted from generation to the next. Biochemistry is the study of the chemical processes that occur between the various cell products that have an influence on the working of the entire body. Molecular biology is similarly the study of biology that is performed in the molecular level of all the components. And finally the developmental biology is the basic study of the major processes occurring in our body that lead to the growth and the development of a new organism. But, to learn about any of these fields, you have to learn more about the basic, that is cell biology.
