Bacteria
The likelihood that we will ever discover every type of bacteria on this planet within our lifetime is pretty slim. I will be discussing research I have done on bacteria. I will be first discussing the classification of bacteria.
The classification of the many types of bacteria started when the first microscopes were created. Bacteria run under the evolutionary chain as prokaryotes. Under these prokaryotes, bacteria are divided by whether they need oxygen or not. Bacteria that need oxygen to survive are called aerobic bacteria. Bacteria under this are called eubacteria. ...
Bacteria that do not need oxygen to survive are called anaerobic bacteria. These bacteria usually live in chains or colonies because of a gel like product that is produced on the cell wall, which allows them to join. ... Also, there is a group of bacteria that do not need oxygen either. ...
Bacteria are also classified by their physical shapes. Bacteria can be spherical (cocci), rod-shaped (bacilli), or corkscrew-shaped (spiochetes). Scientists have also classified bacteria by how they obtain carbon energy. Some bacteria use the process of photosynthesis to obtain energy. ... The last remaining group of bacteria is the heterotrophs, which obtains their energy from decaying organisms or preying on other bacteria.
To obtain the energy from organic compounds the bacteria must carry out fermentation or cellular respiration. ... The type of bacteria designates the end result of fermentation. ...
Bacteria have DNA like other cells, but instead of the helix shaped strand theirs is 1 long strand. ... Bacteria also have ribosomes but theirs are smaller and have a different molecular structure than eukarotic cells.
