What structural features characterise prokaryotes?

Answer 1

"Prokaryotic cells differ significantly from eukaryotic cells. They don't have a membrane-bound nucleus and instead of having chromosomal DNA, their genetic information is in a circular loop called a plasmid. Bacterial cells are very small, roughly the size of an animal mitochondrion (about 1-2µm in diameter and 10 µm long). Prokaryotic cells feature three major shapes: rod shaped, spherical, and spiral. Instead of going through elaborate replication processes like eukaryotes, bacterial cells divide by binary fission."

Answer 2

Prokaryotes lack a true nucleus and organelles, such as mitochondria, in their cells. They have a single circular chromosome and lack membrane-bound organelles. Prokaryotic cells are generally smaller and simpler in structure compared to eukaryotic cells.
