Question

Mitosis and cytoplasmic division function in

• A. Gamete formation in prokaryotes
• B. Growth, tissue repair, and sometimes asexual reproduction in many multicellular eukaryotes
• C. Asexual reproduction of single-celled eukaryotes
• D. Both (a) and (b)

Answer 1

Answer: (B), (C)

The correct options are
B Growth, tissue repair, and sometimes asexual reproduction in many multicellular eukaryotes
C Asexual reproduction of single-celled eukaryotes

• Mitosis and cytoplasmic division is where the cell is divided into 2 daughter cells where the daughter cells are similar to that of the mother cell and have an equal amount of genetic material.
• As most prokaryotes are very simple organisms with a cellular level of organization they do not use sexual ways of reproduction and they reproduce by the act of simply dividing the cell body into 2 by methods such as binary fission, fragmentation, or sporulation.
• In multicellular organisms reproduction usually takes place by the mode of sexual reproduction but the other cells of the body divide and use mitosis for the function of growth, repair, wear and tear, etc.
• But some unicellular eukaryotes such as yeast reproduce by the method of budding which also takes place through the process of mitosis.
• And also some of the multicellular eukaryotes such as planaria reproduce by fragmentation and some of the plants that reproduce or are cultivated using fragmentation are divided by the process of mitosis.
• Therefore options 'Growth, tissue repair, and sometimes asexual reproduction in many multicellular eukaryotes' and 'Asexual reproduction of single-celled eukaryotes' are correct.
