The history of the miscroscope

Extracts from this document...

Introduction

"The History of the Microscope". People look closely at cells for a huge number of reasons. Such as looking for cancer, designing a baby and DNA testing. To do this, because cells are so tiny in size, a microscope is needed to see all of the details that a cell has. In 1665, it was Robert Hooke who was the first person to design and assemble a microscope and see the complexity of a cell. Some years after this, in 1676, Anton van Leeuwenhoek used lenses to observe a variety of unicellular cells which he had placed in drops of water, which he names 'animalcules'. ...read more.

Middle

This was of considerable biological significance because it suggested that there was a common denominator for all living matter. There are two main types of microscope which are used for the study of cells. These are the electron microscope and the light microscope. Electron microscopes are usually considered to be the best option for a scientist because they provide the highest levels of magnification. It was the electron microscope which revolutionised our understanding of cell structure. It has the ability to magnify up to 500 times more than the light microscope, and it revealed the ultrastructure of a cell. There are many advantages of the electron microscope. ...read more.

Conclusion

Before this, however, it opened up a new world of structural detail for a biologist. Like the electron microscope, the light microscope has many advantages and disadvantages. Under a light microscope parts of living plants and animals can be seen directly. This means that you can compare prepared slides with living tissue. However, light microscopes have limited powers of resolution and magnification. Also, because of preservation and staining, what is seen under the microscope may be a result of preparation, rather than the real tissue. Thanks to the development and the continuous improvements made to microscopes, knowledge about cells has progressed a long way. Without it, we would not have been able to develop our understanding of how cells work. ...read more.

    Each thus acquires a full diploid set of chromosomes. This process is repeated again and again as cells divide and the body grows. Sex cells, however, divide in a different way. Sex cells in the adult reproductive organs produce gametes by meiosis. This process consists of two divisions. As the first division proceeds, the homologous chromosomes in the nucleus
