All living things on this planet are made up of cells that are considered to be a living thing's building blocks. Several cells come together to form a living organism. During their entire lifespan, each living being performs various functions such as respiration, excretion, reproduction, etcetera. Our body has different organs to perform these functions. Such organs are made up of different tissue types, and tissue is nothing more than a group of cells. As we know that the human body is composed of many cells (just like bricks form the vital part of a building), and cells make up an organism. Cells are the fundamental component of life. Cells are the smallest living unit of an organism, and all cells have three things in common a cell membrane, Cytoplasm, and DNA. There are two broad categories of cells, The Eukaryotic cells, and Prokaryotic cells.
In 1665, the first biologist Robert Hooke discovered cells. He used an old basic microscope to detect the dead cells in the cork of a tree's bark. He noticed a wall's empty spaces and called them cells because they looked like tiny compartments. Therefore, we can conclude that what Robert Hooke saw looked like a honeycomb-like structure.
The structure and function of cells have now become a blend of basic research and clinical topics. The tools have also expanded with the growth of molecular and analytical techniques. In this Century, especially during the past two or three decades, We also experienced an unparalleled rise in our understanding of the cell, its systemic structure and complexity, its chemical organization, and the specific roles of its sections. This knowledge focused on the efforts that thousands of scientists are working on throughout the world in laboratories.
The importance of cell biology in the 21st Century is that it has helped us in so many ways, and by understanding how cells work in healthy and diseased states, cell biologists are working in the animal, plant, and medical science. We will develop new medicines, more effective drugs, plants with enhanced properties, and a better understanding of how all living things function by increased knowledge.
Eventually, it is and will be more effectively possible to produce a 'health forecast' by analyzing our database of genetic and cell information. Using this, we can take more control over our health in a preventive way. (Lodish et al. 2016) Nevertheless, cell biology is not just about disease. It has greatly assisted the human fertility program. Archeological DNA testing is being used to show how a living person is linked to a long-dead ancestor.
In-plant science was used to show that two different-looking plants have the same genetic background. In Forensic medicine, we are using DNA fingerprints, cell biology, and DNA to help solve murders and assaults. Neither the law courts nor the criminals can escape from Cell biology's importance.
In Biotechnology, we are using cell biology techniques, and information to genetically modify fertilizers to produce appropriate features, to clone animals and plants, to develop and ensure high-quality food is available at lower costs, to manufacture purer drugs and timely organs for the people who are in need for transplants. ( BSCB = British Society for cell biology, founded 1965) (The Company of Biologist )
Cell biology is all about this and is capable of making an exciting career. It is significant for every one of us to feel about how the increase in knowledge about cell biology has affected him or her and our society in general. Our society will need to make informed decisions about such issues as growing organs for human transplantation and growing modified rice to provide nutrients in those areas where vitamin 'A' deficiency causes blindness to produce the vitamin.
A fundamental understanding of cell biology for us is as important as having any awareness, including genetics, of computers and the Internet.
The cell biology of the twenty-first century will put together many distinct branches of biological researches such as taxonomic studies of many organisms, considerable advancement in molecular genetics, moves towards discovering cellular life processes, and new biological systems that will recognize biological objects concerning their broader environment. The Cell biology of the twenty-first century seeks to better understand the mechanisms of a living cell and the increasingly complex structure of metazoan organisms, up to processes functioning at the organism stage, like species and ecosystems. This comprehension, though, is primarily based on synergies between the interpretation of a process. The Cell Biology of the 21st century frequently ties together theoretical work in the field of empirical work in biology. Empirical research was carried out in laboratory experiments or field findings and has contributed to testing for theories as well as developing hypotheses. Hypothesis analysis is focused on the data provided by empirical work to accept or reject a candidate hypothesis. Data collected in empirical work, however, may also suggest new hypotheses, resulting in exploratory work in nature.
In the Cell biology of the 21st century, computational research provides a variety of methods to help experimental study, but also enables a great deal of process biology by techniques such as simulation, data mining, and microarray analysis — and thus underlies the development of possible candidate theories that need to be checked. It should also be remembered that hypothesis testing applies to both reductionist and process biology in the context that both forms of Cell biology are constructed about theories (about components or element relationships) that may or may not be compatible with analytical or experimental outcomes. (John C Wooley and Herbert S Lin, 2005)
