Detailed explanation-1: -Cell size. Typical prokaryotic cells range from 0.1 to 5.0 micrometers (m) in diameter and are significantly smaller than eukaryotic cells, which usually have diameters ranging from 10 to 100 m.

Detailed explanation-2: -Eukaryotic cells are generally bigger-up to 10 times bigger, on average, than prokaryotes. Their cells also hold much more DNA than prokaryotic cells do. To hold up that big cell, eukaryotes have a cytoskeleton (Sy-toh-SKEL-eh-tun).

Detailed explanation-3: -Prokaryotic cells are generally smaller and simpler than eukaryotic cells; in addition to the absence of a nucleus, their genomes are less complex and they do not contain cytoplasmic organelles or a cytoskeleton (Table 1.1).

Detailed explanation-4: -Mycoplasma is the smallest prokaryotic organism (0.15 to 0.35 micrometer) that lacks cell wall but have rigid plasma membrane rich in sterols and lipoglycans. Bacteria are mobile prokaryotic cells with characteristic peptidoglycan cell wall; they range in size from 0.5 to 5 micrometer length.

Detailed explanation-5: -Eukaryotic cells are typically larger than prokaryotic cells, ranging from around 10 to 100 m in diameter. While many eukaryotes consist of multiple cells, there are also single-celled eukaryotes.
