$\fbox \color{blue} Required\:Answer:-$

➢The defining characteristic feature that distinguishes between prokaryotic and eukaryotic cell is the nucleus.

➢In prokaryotic cells, the true nucleus is absent, moreover, membrane-bound organelles are present only in eukaryotic cells.

➢Other major differences between prokaryotic and eukaryotic cells are that prokaryotic cells are exclusively unicellular, while the same does not apply to eukaryotic cells.

Answer:

1. The most fundamental difference is that eukaryotes do have "true" nuclei containing their DNA, whereas the genetic material in prokaryotes is not membrane-bound.
2. Structure and contents of a typical Gram-positive bacterium cell (a prokaryotic cell) magnifyStructure and contents of a typical Gram-positive bacterium cell (a prokaryotic cell)
3. In eukaryotes, the mitochondria and chloroplasts perform various metabolic processes and are believed to have been derived from endosymbiotic bacteria. In prokaryotes similar processes occur across the cell membrane; endosymbionts are extremely rare.
4. The cell walls of prokaryotes are generally formed of a different molecule (peptidoglycan) to those of eukaryotes (many eukaryotes do not have a cell wall at all).
5. Prokaryotes are usually much smaller than eukaryotic cells.
6. Prokaryotes also differ from eukaryotes in that they contain only a single loop of stable chromosomal DNA stored in an area named the nucleoid, while eukaryote DNA is found on tightly bound and organised chromosomes. Although some eukaryotes have satellite DNA structures called plasmids, these are generally regarded as a prokaryote feature and many important genes in prokaryotes are stored on plasmids.
7. Prokaryotes have a larger surface area to volume ratio giving them a higher metabolic rate, a higher growth rate and consequently a shorter generation time compared to Eukaryotes.
