Question

Which pair of values best fills in the blanks in this statement: On average, eukaryotic cells are __________ times longer and have _________ times more volume than prokaryotic cells.

(a) 5, 100
(b) 10, 200
(c) 10, 100
(d) 10, 1000

Answer 1

Eukaryotic cells are on average 10 times longer and have 1000 times more volume than prokaryotic cells. The correct option is (d) 10, 1000

Step-by-step explanation:

The statement that best fills in the blanks would be: On average, eukaryotic cells are 10 times longer and have 1000 times more volume than prokaryotic cells. The diameters of prokaryotic cells range from 0.1 to 5.0 µm, whereas eukaryotic cells are significantly larger, with diameters falling between 10 to 100 µm. This difference in size means that eukaryotic cells also have a much greater internal volume.

Besides, eukaryotic cells have compartmentalization with membrane-bound organelles, which allows them to manage the larger volume. It's the lack of these compartments that gives prokaryotic cells a higher surface-to-volume ratio, facilitating the fast diffusion of ions and organic molecules throughout the cell. The correct option is (d) 10, 1000
