Mitosis
Multiple Choice
In the human body, which cell-division process occurs more frequently over a lifetime, and why?
A
Meiosis, because it produces genetically identical somatic cells for growth, tissue maintenance, and repair throughout the body
B
Mitosis, because it produces genetically identical somatic cells for growth, tissue maintenance, and repair throughout the body
C
Meiosis, because it is required for routine replacement of most body cells such as skin and intestinal epithelium
D
Mitosis, because it occurs only in the ovaries and testes to produce haploid gametes
Verified step by step guidance1
Step 1: Understand the two main types of cell division in the human body: mitosis and meiosis. Mitosis results in two genetically identical somatic cells, while meiosis produces haploid gametes (sperm and egg cells) with half the chromosome number.
Step 2: Identify the primary functions of mitosis and meiosis. Mitosis is responsible for growth, tissue maintenance, and repair by producing identical somatic cells. Meiosis is involved in sexual reproduction by generating gametes.
Step 3: Consider the frequency of each process over a lifetime. Since the body constantly needs to replace and repair somatic cells (like skin and intestinal cells), mitosis occurs frequently throughout life.
Step 4: Recognize that meiosis occurs only in specialized cells within the ovaries and testes to produce gametes, and thus happens less frequently compared to mitosis.
Step 5: Conclude that mitosis is the cell-division process that occurs more frequently over a lifetime because it supports ongoing growth, maintenance, and repair of the body's tissues.
