Scelta multipla
In most animals, where does meiosis primarily take place?
A
In the nucleus of bacteria during binary fission
B
In mature red blood cells circulating in the bloodstream
C
In somatic body tissues such as skin and muscle to support growth and repair
D
In the gonads (ovaries and testes) within germ-line cells that produce gametes
Guida verificata passo dopo passo1
Understand that meiosis is a specialized type of cell division that reduces the chromosome number by half, producing haploid gametes (sperm and eggs) from diploid germ-line cells.
Recall that meiosis does not occur in somatic (body) cells, which divide by mitosis for growth and repair, nor in mature red blood cells, which lack nuclei and do not divide.
Recognize that bacteria reproduce by binary fission, a different process that does not involve meiosis and occurs in the cytoplasm, not the nucleus.
Identify that meiosis primarily takes place in the gonads (ovaries and testes) of animals, where germ-line cells undergo meiosis to produce haploid gametes.
Conclude that the correct location for meiosis is within the germ-line cells in the gonads, as this is essential for sexual reproduction and genetic diversity.
