Questions: Which of the following statements describes correct naming of bacterial cells? a. Genus name (capitalized in italics) and species name (lowercase in italics) b. Genus name (lowercase in italics) and species name (lowercase in italics) c. Species name (capitalized) and species name (lowercase) d. Genus name (capitalized) and species name (lowercase)

The answer is the first one (or A): Genus name (capitalized in italics) and species name (lowercase in italics).

Explanation for each option: a. Genus name (capitalized in italics) and species name (lowercase in italics) - This is the correct format for naming bacterial cells according to the binomial nomenclature system. The genus name is always capitalized and italicized, while the species name is lowercase and italicized.

b. Genus name (lowercase in italics) and species name (lowercase in italics) - This is incorrect because the genus name should be capitalized.

c. Species name (capitalized) and species name (lowercase) - This is incorrect because the genus name should be capitalized and italicized, and the species name should be lowercase and italicized.

d. Genus name (capitalized) and species name (lowercase) - This is incorrect because both the genus and species names should be italicized.

Summary: The correct naming convention for bacterial cells is to have the genus name capitalized and italicized, and the species name lowercase and italicized. Therefore, the correct answer is option A.
