Answer:
D
Step-by-step explanation:
Eukaryotic cells are usually bigger than prokaryotic cells. Generally, prokaryotes cels size will range between 1 and 10 micrometers while that of eukaryotes will range between 10 – 30 micrometers. Due to the small cell size of prokaryotes, elements can diffuse in and out of the whole cell. However, for eukaryotes, cellular mechanism need to assist the distribution (in and out) of elements in the cell.
