Question

______ a. The largest group of related microbes within domain Bacteria, including many chemo organotrophs, phototrophs, and chemolithotrophs ________ b. The smallest "free - living cells" capable of independent growth; although lacking a cell wall, they belong to the Gram (+) group of bacteria ______ c. A group of Bacteria with a number of unusual morphological features: a protein stalk, compartmentalization of the DNA within a "nuclear envelope", and division by budding _______ d. A group of oxygenic phototrophs belonging to domain Bacteria that were critical to the evolution of future life on Earth ____ e. A group of helical Bacteria that cause Lyme disease and syphilis _______ f. Strict anaerobes of domain Archaea that produce methane as a byproduct of their metabolism ________ g. Extremophiles from domain Archaea that require large amounts of sail for survival; some contain pigments that can capture light and use it to make ATP.

Explanation / Answer

A) Proteobacteria : The largest group of related microbes within domain bacteria

B) Mycoplasma : the smallest free living cells capable of independent growth.

C) planctomycetes : a group of bacteria having nuclear envelope and division by budding.

D) Cyanobacteria: oxygenic phototrophs belonging to domain bacteria.

E) spirochetes : group of helical bacteria causing Lyme disease and syphil-is.

F) methanogens : strict anaerobes of domain archea that produce methane as a byproduct of their metabolism.

G) halobacteria : extremophiles from domain archaea that require large amounts of salt for survival; some contain pigments that can capture light and use it to make ATP.
