Multiple Choice
In eukaryotic cells, mitosis is NOT used for which of the following processes?
A
Replacing cells during normal turnover in tissues such as skin
B
Generating gametes with half the chromosome number (haploid cells)
C
Producing genetically identical daughter cells for growth and tissue repair
D
Asexual reproduction in some organisms (e.g., budding in yeast)
Verified step by step guidance1
Step 1: Understand the role of mitosis in eukaryotic cells. Mitosis is a process of cell division that results in two genetically identical daughter cells, each with the same chromosome number as the parent cell.
Step 2: Identify the processes where mitosis is involved. These include replacing cells during normal turnover (like in skin), producing genetically identical cells for growth and tissue repair, and asexual reproduction in some organisms such as budding in yeast.
Step 3: Recognize that generating gametes (sperm and egg cells) with half the chromosome number (haploid cells) is not a function of mitosis but of meiosis, a different type of cell division.
Step 4: Compare the options given and note that the process of generating haploid gametes is distinct from mitosis because it involves reduction division to halve the chromosome number.
Step 5: Conclude that mitosis is NOT used for generating gametes with half the chromosome number, which is the correct answer to the problem.
