Detailed explanation-1: -Prokaryotic cells lack a true nucleus. The nucleus is devoid of the nuclear membrane. On the contrary, the nucleus of the eukaryotic cells is enclosed by a nuclear membrane. A prokaryotic cell also lacks mitochondria and chloroplast, unlike a eukaryotic cell.

Detailed explanation-2: -Most bacteria rely on binary fission for propagation. Conceptually this is a simple process; a cell just needs to grow to twice its starting size and then split in two.

Detailed explanation-3: -Binary fission is when an organism splits into two identical individual organisms without sex taking place. It is a type of asexual reproduction which often occurs in prokaryote micro-organisms. Some organelles among eukaryotes reproduce using binary fission.

Detailed explanation-4: -Prokaryotes such as E. coli, Archaea as well as eukaryotes such as euglena reproduce through binary fission.

Detailed explanation-5: -Steps of binary fission Like a human cell, a dividing bacterium needs to copy its DNA. Unlike human cells, which have multiple linear (rod-like) chromosomes enclosed in a membrane-bound nucleus, bacterial cells usually have a single, circular chromosome and always lack a nucleus.
