1. World Of Microbiology Flashcards
(21 cards)
The three domains of life
Bacteria, Archaea, Eukarya
Three domain system of classification is based on differences in which of the following molecules?
rRNA
……….. is a population of microbial cells growing in the absence of other species or types
Pure Culture
…………. is the genetic material of all the microbes - bacteria, fungi, Protozoa and viruses- that live on and inside the human body
Microbiome
…………. are “ecological communities of Commensal, symbiotic, and pathogenic microorganisms” that literally share our body space.
Microbiota
Difference between Anaerobic and Aerobic Bacteria?
Anaerobic are single called organisms that don’t need oxygen to survive, Aerobic are bacteria that can grow and survive when it is oxygen
The …….. is the genetic makeup of a cell, an organism, or an individual usually with reference to a specific characteristic under consideration
Genotype
How do we get our microbiome?
During the birth, breast feeding, environment
Which types of microorganism has organism as Bacteria and Archaea?
Prokaryotic Organisms
Which types of microorganism has organism as Fungi, Protozoa and Algea?
Eukaryotic microorganisms
……….(single type of cells) Mostly live in communities and arranged in pairs, chains, clusters or other groupings
Unicellular
……………. is a polymer consisting of sugar and amino acids that forms a mesh like layer outside the plasma membrane of most bacteria that forms the cell wall.
Peptidoglycan cell wall
“………..” are small single celled organisms, they are 10 times as many “………….” cell as human cells in the human body
Bacteria
How do bacteria RePRODUCE?
Bacteria reproduce by “binary fission. “ . in this process the bacterium divides into two identical daughter cells. “.binary fission” begins when the DNA of the bacterium splits into two replicates. The bacteria cell than elongates and splits into two daughter cells each with identical DNA as their parent cell.
Single-celled prokaryotic organism, they are “Extremophiles” that means they are adapted to extreme environments( very hot, cold, saline, acidic) which bacteria is that?
Archaea
Singular cells have also nucleus. 3 mayor groups: YEASTS, FUNGI AND MUSHROOMS. are multicellular except for YEAST. Their cell walls are CHITIN, that is a composed of filaments
Fungi eukaryotic microorganisms
Unicellular eukaryotes, they are diverse group, may be motile via pseudopods, cilia or flagella.
Protozoa eukaryotic microorganism’s
May be unicellular or multicellular, the cell was is made of Cellulose. It is found in freshwater, saltwater. It uses photosynthesis for energy. It also produces oxygen and carbohydrates
.Algae eukaryotes cell
Its acellular, consist of DNA and RNA core, and the core is surrounded by a protein coat. Protein coat may be enclosed with in a lipid envelope. They only replicate when they are living in a host cell.
Virus
They are Eukaryotes and is find in multicellular animals, not strictly a microorganism.
Multicellular animal Parasites.
Bacteria is classified into five groups according to their basic shapes:
Spherical (cocci), Rod (bacilli), spiral ( spirilla), comma (vibrios) or corkscrew (spirochaetes)
