Detailed explanation-1: -Organisms which reproduce asexually cannot undergo meiosis, whereas all eukaryotic organisms undergo mitosis. Mitosis and meiosis are similar in that both can only occur in eukaryotic cells. This is because prokaryotic cells do not contain a nucleus within which to begin the processes of mitosis and meiosis.
Detailed explanation-2: -The precise timing and formation of the mitotic spindle is critical to the success of eukaryotic cell division. Prokaryotic cells, on the other hand, do not undergo mitosis and therefore have no need for a mitotic spindle.
Detailed explanation-3: -Mitosis is common to all eukaryotes; during this process, a parent cell splits into two genetically identical daughter cells, each of which contains the same number of chromosomes as the parent cell. Meiosis, on the other hand, only occurs in eukaryotic organisms that reproduce sexually.
Detailed explanation-4: -The cells formed after binary fission are genetically identical. There is no spindle apparatus formed in case of binary fission. So the answer is ‘no’, prokaryotes do not undergo mitosis or meiosis. The division in prokaryotic cells is by binary fission.
Detailed explanation-5: -Prokaryotic cells can reproduce asexually only through binary fission. Binary fission is the process by which a bacterial cell splits into two identical daughter cells. This is a very fast process and contributes to the rapid growth and replication of bacteria. Mitosis and meiosis are only found in eukaryotic cells.
