Concept explainers
(a)
To determine: The mass of a single cell.
Introduction:
Escherichia coli (E. coli) is a type of “Gram-negative bacterium” found in the intestine of animals. This bacterium looks like a rod (a cylinder).
(b)
To determine: The percentage of total volume of the bacterium occupied when cell envelope is 10 nm thick.
