Biology 11: Kingdom Monera
Terms in this set (37)
One of the five kingdoms of life. Organisms in this kingdom are all prokaryotic cells called bacteria.
the study of microorganisms
being present everywhere at once
A layer of polysaccharid or protein on top of cell wall that protects pathogenic bacteria from phagocytic cells.
A hairlike extension that aids in communication and exchange of genetic material in prokaryotes
A lash-like appendage used for locomotion in some bacteria and protozoa
a small cellular inclusion consisting of a ring of DNA (usually drug resistant genes) that is not in a chromosome but is capable of autonomous replication
Bacteria that can live in extreme conditions sans oxygen; Most primitive
Largest group of bacteria
Photosynthetic bacteria containing a blue pigment in addition to chlorophyll
3 Types of Bacteria Shapes
Bacilli (rod-shaped), Cocci (circle-shaped) and Spiral.
cocci in pairs
chain of cocci
grape-like clusters of cocci
chain of bacilli
Gram Positive bacteria
Bacteria with thick cell walls containing peptidoglycans; these cells turn purple when stained.
Gram Negative bacteria
Bacteria with cell walls bounded by a second outer membrane containing lipids; these bacteria turn red when stained.
5 Modes of Bacteria Movement
a) By flagellum
b) Lash/snake/spiral forward
c) glide slowly along slime layer secrete
Organisms that are able to make their own food
Bacteria that make their own food by way of photosynthesis
Bacteria that obtain their energy from inorganic chemicals such as sulfur, nitrites, and iron
Organisms that gain nutrients from food produced by other organsims
Organisms that are able to obtain some nutrients by photosynthesis and others from other organisms
Organism that can obtain energy by taking in organic molecules and breaking them down
take organic molecules for nutrition from living organisms
bacteria that derive their nutrition from dead organic matter
Energy production NOT requiring oxygen in bacteria
Energy production requiring oxygen; produces 3X as much energy as fermentation
Prokaryotes that require a constant supply of oxygen in order to live
Prokaryotes that must live in the absence of oxygen
Prokaryotes that can live with or without oxygen
asexual reproduction in single-celled organisms by which one cell divides into two cells of the same size
asexual reproduction in which a part of the parent organism pinches off and forms a new organism
Form of sexual reproduction In bacteria through direct transfer of DNA between two cells that are temporarily joined.
A thick-walled protective spore that forms inside a bacterial cell and resists harsh conditions
Beneficial effects of monerans
Food production (cheese, vinegar etc.), Industrial usage (mining), Digestion & Vitamin Production, Sewage decomposition, Nitrogen Fixation
Methods to control Bacterial Disease
Sterilization, Refrigeration, Antibiotics (eg. Erythromycin, Penicillin, Immunization)
