Bibliographic Information

Though scientists had been using microscopes for centuries, they were not always sure what they were looking at. Robert Hooke's initial observation in of plant-cell walls in slices of cork was followed shortly by Antonie van Leeuwenhoek's first descriptions of live cells with visibly moving parts.

In the s two scientists who were colleagues — Schleiden, looking at plant cells, and Schwann, looking first at animal cells — provided the first clearly stated definition of the cell. Their definition stated that that all living creatures, both simple and complex, are made out of one or more cells, and the cell is the structural and functional unit of life — a concept that became known as cell theory.

As microscopes and staining techniques improved over the nineteenth and twentieth centuries, scientists were able to see more and more internal detail within cells. The microscopes used by van Leeuwenhoek probably magnified specimens a few hundredfold.

Today high-powered electron microscopes can magnify specimens more than a million times and can reveal the shapes of organelles at the scale of a micrometer and below. With confocal microscopy a series of images can be combined, allowing researchers to generate detailed three-dimensional representations of cells.

These improved imaging techniques have helped us better understand the wonderful complexity of cells and the structures they form.

There are several main subfields within cell biology. One is the study of cell energy and the biochemical mechanisms that support cell metabolism. As cells are machines unto themselves, the focus on cell energy overlaps with the pursuit of questions of how energy first arose in original primordial cells , billions of years ago.

The Hidden Life of the Cell

In the case of human infections, unavoidable delays occur between the time a person is exposed to bacteria, becomes sick, and provides a sample for culture; the culture grows; the bacterium is identified in the laboratory, grown on media for transportation, and sent to a second laboratory; a pattern is determined; and matches are identified. There are no diagrams and everything is explained using words alone, which is not how to teach biology.

Organelles perform specific functions such as photosynthesis and protein production. Mobile genetic elements: Prokaryotic cells are found only in microscopic organisms such as bacteria and archaea. He seemed a wise tour guide with an encyclopaedic knowledge, who wrote clearly and beautifully about biology and society.

I fancy reading books keenly. Look over my other articles. I have always been a very creative person and find it relaxing to indulge in volunteer.
