Final answer:
Mitosis is a type of cell division resulting in genetically identical daughter cells; plant root cells, human cheek cells, and whitefish blastula cells divide by mitosis. Gametic cells divide by meiosis, producing cells with half the DNA for sexual reproduction. The correct options for cell types dividing by mitosis are plant root cells, human cheek cells, and whitefish blastula cells.
Step-by-step explanation:
Understanding Mitosis in Different Cell Types
In biology, particularly in cell division, mitosis is a process that results in the formation of two daughter cells that are genetically identical to the parent cell. Through thousands of rounds of this type of cell division, an adult organism is developed from diploid cells. Plant root cells, human cheek cells, and whitefish blastula cells are examples of cells that divide through mitosis. It is during mitosis that the duplication of DNA ensures each new cell has the same genetic material as the parent cell.
Conversely, gametic cells divide through a different process called meiosis, which results in cells with half the normal DNA, meant for sexual reproduction. Unlike mitosis, meiosis produces cells that are not genetically identical to their parent cells.
The cell types that divide by mitosis to create new genetically identical cells are plant root cells, human cheek cells, and whitefish blastula cells. These cells perform vital roles in the growth, development, maintenance of health, and asexual reproduction in some organisms. The division times for these cells can vary, reflecting the dynamic nature of cell division in living organisms.
Thus, the correct options are: plant root cells, human cheek cells, and whitefish blastula cells.
