Mitosis and meiosis are both ways in which cells:
A
generate ATP through cellular respiration
B
divide to produce new cells
C
transport materials across the plasma membrane
D
synthesize proteins
검증된 단계별 안내1
Understand the purpose of mitosis and meiosis: Both are processes of cell division, but they serve different purposes. Mitosis is responsible for producing two genetically identical daughter cells for growth, repair, and asexual reproduction. Meiosis, on the other hand, produces four genetically diverse gametes (sperm or egg cells) for sexual reproduction.
Eliminate incorrect options: The first option, 'generate ATP through cellular respiration,' is unrelated to cell division. Cellular respiration occurs in the mitochondria and is a process for energy production, not cell division.
Analyze the second option: 'Divide to produce new cells' is directly related to the purpose of both mitosis and meiosis. Mitosis produces new somatic (body) cells, while meiosis produces gametes. This aligns with the primary function of these processes.
Evaluate the third option: 'Transport materials across the plasma membrane' is a function of cellular transport mechanisms like diffusion, osmosis, and active transport, not mitosis or meiosis.
Consider the fourth option: 'Synthesize proteins' is a function of ribosomes during translation, part of gene expression, and is not directly related to mitosis or meiosis. Therefore, the correct answer is the second option, as it accurately describes the role of mitosis and meiosis in cell division.
