LiRa [457]

Answer:

Eukaryotic cells typically have circular chromosomes, whereas prokaryotic cells typically have linear chromosomes.

Explanation:

Prokaryotic and Eukaryotic cells are the two kinds of cells that living organisms are composed of. Eukaryotic cells are cells that possess a membrane-bound nucleus while prokaryotic cells do not possess a membrane-bound nucleus. The cell membrane of eukaryotes contain ester-linked phospholipids, whereas that of prokaryotes (bacteria and archeae) have ether-linked or ester-linked phospholipids.

Peptidoglycan is the major constituent of the cell wall of many prokaryotes (bacteria) while peptidoglycan is absent in the cell wall of eukaryotes that possess it. One notable difference between eukaryotic and prokaryotic cells is the SHAPE OF THEIR CHROMOSOME.

- The chromosome in eukaryotic cells is LINEAR while that in prokaryotic cells is CIRCULAR in shape.
