Eubacteria are considered to be "true bacteria," according to Reference.com. They are characterized by a lack of nuclear membrane, single circular chromosome and have cell walls composed of peptidogycan.Continue Reading
A popular classification system divides all living beings into three domains: eubacteria, archaea and eukaryotes. The word "eubacteria" derives from the words "eu," which means "true" and "bacteria." Eubacteria are prokaryotes, which mean they have a primitive nucleus. The nuclear material of bacteria is not bound by a distinct nuclear membrane, as in eukaryotes. Also, bacterial genetic material, or the DNA, is present as a single circular chromosome.
The cell wall of bacteria is composed of peptidoglycan, as opposed to cellulose, like in plants. They are single celled organisms, and mostly reproduce through binary fission. Eubacteria are either motile, or non-motile. The motile bacterium are able to move, due to the presence of a flagellum.
Eubacteria can form spores, which allows them to survive for a long time in adverse conditions, notes the Augusta Technical College. Eubacteria are further classified as either gram positive bacteria, or gram negative bacteria, depending on whether or not they take in a gram stain. Eubacteria and Archaebacteria evolved from a common ancestor, but have enough differences to merit two separate domains in the classification of living beings.Learn more about Biology
Gram staining separates bacteria into two classes, Gram-positive and Gram-negative, allowing medical providers to determine an appropriate antibiotic to prescribe a patient, according to Reference.com. The cell wall, which is the protective coating of the bacteria, determines the outcome of this test.Full Answer >
According to Spark Notes, eubacteria comprise an ancient group and can be saprophytes, photoautotrophs or symbionts. Eubacteria are also known as the true bacteria. They are able to reproduce by binary fission, with a split approximately every 20 minutes.Full Answer >
Eubacteria fall into four primary categories, which are gram-positive eubacteria, proteobacteria, cyanobacteria and spirochetes. Eubacteria are much more common than archaebacteria, which are closely related members of the prokaryote division. Eubacteria live in many areas around the world, including some of the most extreme and inhospitable environments.Full Answer >
While agriculture is the growing of plants as crops and animals for food, biology is the study of life, which broadly divides into plants and animals, according to Reference.com. The two relate closely and intertwine often. The best agricultural practices make use of lessons learned from biology.Full Answer >
