Question

14. In each round of bacterial sporulation, one cell produces_ spore(s), while in fungal sporulation, one cell produces_ spore(s). • one; many • many, many • one; one • many; one 15. (True/false) During bacterial sporulation, the sporulating cell has to replicate its chromosome so that one chromosome is put into the spore while the other chromosome remains with the original cell. • True False 16. Only Gram positive bacteria can sporulate due to the presence of the Thick cell wall • Thin cell wall • Outer membrane • Cell membrane • Lipoteichoic acids 17. Predict which type of metabolic classification is represented by the data below. Metabolism Terminal electron acceptor Electron source Carbon source Fructose H2 Fe3+ Fructose CO2 • • • A is chemsargapobetecatrophic; B is chemolithoautotrophic A is chemolithoautotrophic; B is shemaargangbeteratrophis A is chemolithoheterotrophic, B is shemareangautotraphic • A is chemgheteroautotrophic: B is shemalitboorganotrophic 18. Many Eukaryotic and Prokaryotic microorganisms use aerobic respiration as their primary metabolism. Which curve represents the growth of an aerobically respiring yeast cell versus the growth of an aerobically respiring bacterial cell? • Curve B is yeast; Curve A is bacterial • Curve A is yeast; Curve B is bacterial Curve A Curve B Log # cells/mL Time

the highlighted choices are what i think the answer is...please correct whats wrong.

Answer 1

14. One bacterial cell usually produces only one endospore. Many species of microscopic fungi are capable of producing a comparable number of spores. Option A is correct,

15. Sporulation, a single chromosome is partitioned into two separate domains of unequal sizes. During vegetative growth, the individual daughter chromosomes are separately and symmetrically condensed following their replication.SO it's false.

16. Endospore formation is usually triggered by a lack of nutrients and usually occurs in gram-positive bacteria. In endospore formation, the bacterium divides within its cell wall, and one side then engulfs the other. Endospores enable bacteria to lie dormant for extended periods, even centuries.

17. Chemolithoautotrophic means that these organisms obtain the necessary carbon for metabolic processes from carbon dioxide in their environment. So option A is correct.

18. Bcterial cell divides faster than yeast cell. So Curve A is bacteria and curve B is yeast.
