Question

The following are examples of classification schemes that are used in bacteria. Which schemes provide useful information about the phylogeny of the organisms that fall into these categories? For each category you must say why, or why not.
(A) Photosynthetic
(B) Archaea
(C) Pathogenic
(D) Gram negative

Answer 1

Answer:

Photosynthetic: a portion of the microscopic organisms are photosynthetic in nature they can utilize carbon dioxide and daylight for the development of nourishment. Model: cyanobacteria or blue green growth.  

Other microscopic organisms are heterotrophic in nature they are not ready to incorporate nourishment without anyone else and relies on living and nonliving material for their supplements. Model pseudomonas, staphylococcus. These are chemotrophic, organ trophic and so forth.  

Archaea: it is a gathering of archaea which are considered as associating join among eukaryote and prokaryote. Archaea are considered as archaebacterial yet don't have a place with the gathering of Bacteria. They have unmistakable highlights then microscopic organisms that is the reason they set in various gathering. A large portion of the archaebacterial are extremophiles and they don't present in ordinary condition where typical microscopic organisms are available. Because of their territory they have diverse basic and practical properties.  

Pathogenic: a portion of the gathering of Bacteria are pathogenic in nature implies they can make malady any host. Pathogenic microscopic organisms are unique in relation to nonpathogenic microbes in auxiliary design and utilitarian properties. They have wide scope of host from plant and creatures. Pathogenic microbe’s displays polysaccharide covering, poisons, containers, discharges, compounds and so on. These all things give them pathogenic properties.  

Gram negative: Gram recoloring is a strategy for recoloring the phone mass of microorganisms by which we can recognize gram positive and Gram Negative microbes. It is given by researcher Christian Graham in which we use Crystal Violet to recognize Gram Positive Bacteria. Gram Negative microbes don't take-up Crystal Violet and they are recolored by counterstain safranin.

Answer 2

Answer: A, B, D provide useful information on the phylogeny of the bacteria that fall in those categories

Explanation: Some bacteria can use carbon dioxide and sunlight for the formation of food, hence, photosynthetic.

Archaebacteria are single celled bacteria that lacked nuclei. They can survive in extreme environments like very salty, very acidic, and very hot surroundings.

Gram-negative bacteria describes bacteria that does not retain the crystal violet stain used in the Gram staining method of bacterial differentiation.

Pathogenic bacteria does not provide any information on the evolutionary history of bacteria. It is useful in classifying bacteria on the basis of disease causing or not.
