What characteristics distinguish protists from bacteria?
Protists have nucleus and double membranous organells.Bacteria do not have them.
Bacteria are classified as either gram positive or gram negative based on their ability to absorb gentian violet dye into their cell walls True or False?
True. Gram staining is a common technique used to distinguish between different groups of bacteria based on differences in their cell wall structure. Gram positive bacteria retain the violet dye and appear purple, while gram negative bacteria do not retain the dye and appear pink.
Why gram stain is called differential stain?
Gram stain is called a differential stain because it differentiates bacteria into two major groups based on the differences in their cell wall composition. This staining technique allows us to distinguish between Gram-positive bacteria, which retain the crystal violet dye, and Gram-negative bacteria, which do not retain the dye and instead take up the counterstain, usually safranin.
Ribosomal differences have put bacteria into what two kingdoms?
Eubacteria and Archeabacteria.
Why are cultural and biochemical characteristics so important for assigning bacteria to a taxonomic group?
Cultural and biochemical characteristics are important for assigning bacteria to a taxonomic group because they provide valuable information about the physiology and genetic makeup of the bacteria. Cultural characteristics, such as growth requirements and appearance on agar media, can help distinguish between different bacterial species. Biochemical characteristics, such as metabolic capabilities and enzyme production, can provide insights into the biochemical pathways and metabolic capabilities of the bacteria. These characteristics are essential for the accurate classification and identification of bacteria within taxonomic groups.
Does the presence of nuclei in fungi as well as its ability to reproduce asexually distinguish from bacteria?
Those are two of many characteristics that distinguish fungi from bacteria.
Why is important to distinguish between Gram-positive and Gram-negative bacteria in diagnosing a bacterial infection?
gram- negative and gram- positive bacteria differ in their response to different antibiotics
What causes differences in cheese?
bacteria
How do the two members of the two domains of prokaryotes differ?
there are important differences in the structure and chemical makeup of their cells.Some prokaryotes are unicellular, and others are multicellular.Although bacteria and archaea are similar in some ways, there are important differences in the structure and chemical makeup of their cells.
What characteristics distinguish protists from bacteria?
Protists have nucleus and double membranous organells.Bacteria do not have them.
The three-domain system recognizes fundamental differences between two groups of?
The three-domain system recognizes fundamental differences between the Archaea, Bacteria, and Eukarya domains. These differences are based on genetic, biochemical, and structural characteristics that distinguish each domain from one another. This system has replaced earlier classification systems that grouped all organisms into either plants or animals.
Bacteria are classified as either gram positive or gram negative based on their ability to absorb gentian violet dye into their cell walls True or False?
True. Gram staining is a common technique used to distinguish between different groups of bacteria based on differences in their cell wall structure. Gram positive bacteria retain the violet dye and appear purple, while gram negative bacteria do not retain the dye and appear pink.
What method is used to distinguish the two types of bacteria?
One common method to distinguish between different types of bacteria is Gram staining. This method involves staining bacteria with crystal violet and iodine, followed by a decolorization step and counterstain. Based on whether bacteria retain the stain (Gram-positive) or not (Gram-negative), they can be differentiated.
A gene that makes it possible to distinguish bacteria that carry the plasmid from those that dont?
Genetic marker.
Why gram stain is called differential stain?

Why are contrasting colors important in gram staining?
# Suppose you performed a gram stain on a sample from a pure culture of bacteria and observed a friend of red and purple cocci. Adjacent were not always the same color. What do you conclude? # ## The bacteria was not a pure culture.
In regards to taxonomic classification of bacteria what is the relationship between physiological and genetic differentiation of bacteria?
You're lame typing the answer as exactly as it is on the lab manual......I.V. Genetic differences between bacteria causes specific physiological differences among the bacteria, such as certain morphological characteristics as well as what compounds the bacteria can ferment and produce as by-products in this process.
