Question

A primary spermatocyte matures into ________ spermatids having ________ chromosomes.

A) millions of
B) thousands of
C) haploid, 23
D) diploid, 46

Answer 1

A primary spermatocyte matures into haploid 23 spermatids having spermatids having haploid 23 .

C) haploid 23

Step-by-step explanation:

A primary spermatocyte undergoes meiosis a process that involves two successive divisions resulting in the formation of haploid cells called spermatids. During the first division meiosis I the primary spermatocyte which is initially diploid 2n divides into two haploid secondary spermatocytes each with half the chromosome number n. In the second division meiosis II each secondary spermatocyte divides into two spermatids.

Now let's break down the chromosome count. A diploid cell has a total of 46 chromosomes 2n which includes pairs of homologous chromosomes. As the primary spermatocyte undergoes meiosis the chromosome number is halved. Therefore each secondary spermatocyte has 23 chromosomes n and subsequently each spermatid also has 23 chromosomes.

In summary the primary spermatocyte matures into haploid spermatids each having 23 chromosomes. This reduction in chromosome number is crucial for maintaining the correct chromosome count in the offspring when the spermatids eventually develop into spermatozoa through further differentiation processes. The correct answer is C) haploid 23 as it accurately reflects the maturation process of spermatocytes into spermatids and the resulting chromosome count.

Answer 2

A primary spermatocyte matures into haploid spermatids having 23 chromosomes. Correct answer is option c. haploid, 23

Step-by-step explanation:

Primary Spermatocyte Matures Into Haploid Spermatids, which states that a primary spermatocyte matures into haploid spermatids. This is accurate. Spermatogenesis involves the process of cell division, transforming diploid spermatogonia into haploid spermatids. Chromosomes in Spermatids Haploid cells have half the number of chromosomes as diploid cells. In humans, the haploid number is 23 and this applies to spermatids.

The term haploid refers to cells that contain a single set of chromosomes, and in the context of spermatogenesis, it denotes the mature sperm cells spermatids. The number 23 signifies the specific chromosome count in these haploid cells.

This process is vital for sexual reproduction as it ensures genetic diversity in the offspring by shuffling and recombining genetic material.

Thus, Correct answer is C. haploid, 23
