Multiple Choice
In multicellular eukaryotes, what is the primary function of mitotic cell division?
A
To increase genetic variation by recombining homologous chromosomes during synapsis
B
To reduce the chromosome number by half to form gametes for sexual reproduction
C
To generate ATP by splitting glucose into pyruvate in the cytosol
D
To produce two genetically identical daughter cells for growth, tissue repair, and asexual reproduction
Verified step by step guidance1
Step 1: Understand the context of mitotic cell division in multicellular eukaryotes. Mitosis is a process where a single cell divides to produce two daughter cells.
Step 2: Recall that mitosis results in daughter cells that are genetically identical to the parent cell, maintaining the same chromosome number.
Step 3: Differentiate mitosis from meiosis, where meiosis reduces chromosome number by half and increases genetic variation through recombination during synapsis.
Step 4: Recognize that mitosis is primarily involved in growth, tissue repair, and asexual reproduction, rather than producing gametes or generating ATP.
Step 5: Conclude that the primary function of mitotic cell division is to produce two genetically identical daughter cells to support these biological processes.
