4: Bacteria - Cell Walls
Bacteria in Nature pp Cite as. By nature, humans are inquisitive animals: this is the foundation of scientific investigation. However, we sometimes have difficulty in comprehending, and therefore interpreting, the data; this is especially true when working with systems much different from those of our own experience. In these cases, we are forced to attempt to comprehend the system by the use of analogy. For example, when describing the nature of fundamental quark particles, nuclear physicists have allocated to them the characteristics of flavor and color.
The Structure of Bacteria
The bacterium, despite its simplicity, contains a well-developed cell structure which is responsible for some of its unique biological structures and pathogenicity. Many structural features are unique to bacteria and are not found among archaea or eukaryotes. Because of the simplicity of bacteria relative to larger organisms and the ease with which they can be manipulated experimentally, the cell structure of bacteria has been well studied, revealing many biochemical principles that have been subsequently applied to other organisms. Perhaps the most elemental structural property of bacteria is their morphology shape. Typical examples include:. Cell shape is generally characteristic of a given bacterial species, but can vary depending on growth conditions. Some bacteria have complex life cycles involving the production of stalks and appendages e.
Formation and function of bacterial organelles
They are as unrelated to human beings as living things can be, but bacteria are essential to human life and life on planet Earth. Although they are notorious for their role in causing human diseases, from tooth decay to the Black Plague, there are beneficial species that are essential to good health. For example, one species that lives symbiotically in the large intestine manufactures vitamin K, an essential blood clotting factor. Other species are beneficial indirectly.
It is important to note that not all bacteria have a cell wall. The two different cell wall types can be identified in the lab by a differential stain known as the Gram stain. Originally, it was not known why the Gram stain allowed for such reliable separation of bacterial into two groups. Once the electron microscope was invented in the s, it was found that the staining difference correlated with differences in the cell walls. Here is a website that shows the actual steps of the Gram stain.

Северная Дакота - призрак, сказала она. Сплошная мистификация. Блестящий замысел.
Хакеры подобны гиенам: это одна большая семья, радостно возвещающая о любой возможности поживиться. Лиланд Фонтейн решил, что с него довольно этого зрелища. - Выключите, - приказал. - Выключите эту чертовщину. Джабба смотрел прямо перед собой, как капитан тонущего корабля.
Беккер безучастно кивнул: - Так мне сказали. Лейтенант вздохнул и сочувственно помотал головой. - Севильское солнце бывает безжалостным. Будьте завтра поосторожнее. - Спасибо, - сказал Беккер.
Приближающаяся медсестра прямо-таки кипела от возмущения.
