Microscopy plays a critical role in a majority of life sciences.
Microscopes have contributed significantly in the fields of cell biology and histology where great discoveries have been made over the years. The discovery of blood cells in the human body paved the way for advanced studies in cell biology.
Early discovery of genes involved in human development by Edward Lewis, Christine Nusslein and Eric Wieschaus in 1995 is a clear demonstration of the importance of microscopes in the life sciences.
The biological systems are composed of vast complexities, which can be better understood though the use of microscopes. A microscope allows scientists to view detailed relationships between the structures and functions at different levels of resolution.
Microscopes have continued to be improved since they were first invented and used by early scientists like Anthony Leeuwenhoek to observe bacteria, yeast and blood cells.

When discussing microscopy the compound light microscope is the most popular and usually brings back memories of biology classes in the lab. Also, the stereo microscope can be used in the life sciences to view large samples or materials.
The basic premise is that the microscope is used to greatly magnify objects/specimens. This hasn't changed but instead has become increasingly more powerful and with various microscopy imaging techniques employed to make certain types of observations.
In biology, Cryo electron microscopy has become an important tool in determination of the 3D structure of the complexes of macromolecules at the subnanometer resolution. Moreover, it has been used to observe helical as well as 2D crystalline specimens.
These microscopes have also been used to achieve near-atomic resolution, which have been instrumental in the study of biological functions of different molecules in atomic detail.
With the combination of a number of techniques such as X-ray crystallography, microscopy has also been able to achieve greater precision, which has been used as a phasing model to solve crystallographic structures of a variety of macromolecules.
In histology, microscopy is used to study fine details of biological cells and tissues. Microscopy finds a wide range of use in autopsy, diagnosis for treatment and education just to mention a few.
Histology, which is the microscopic study of tissues, would not be possible without the use of microscopes. A histologist will be able to learn valuable information with regards to the functional morphology of both human beings and animal. This helps with important discoveries concerning the cells and body systems. See Histology Slides.
The importance of microscopes in life sciences can never be overestimated. Following the discovery of blood cells among other micro-organisms, many other discoveries were made through the use of advanced instruments. Some of the other discoveries made include;
Many other discoveries have been made since the 1670s and have contributed significantly in a variety of studies that have seen major advancements in the treatment of diseases and the development of cures.
It is now possible to study diseases and how they progress within the human body so as to better understand how to treat them.
Due to the many applications, data used in cell biology has transformed significantly from non-quantitative representative observations in the fixed cells to high-throughput quantitative data in the living cells.
In conclusion, it is safe to say that microscopes have played a central part in life sciences.
This has positively contributed to the enhancement of quality of life since a lot of discoveries directly contributed to the development of drugs and cures used in the treatment of diseases and conditions that were previously misunderstood or not well understood.
A cell is the single unit of life, and to understand and study it, the microscope is necessary. The discovery of cells and genes were major milestones in the medical sciences and were a great influence to the development of new effective cures and a reduction of mortality cases among populations.
