CHAPTER 22: THE REPRODUCTIVE SYSTEMS
1.Briefly explain why human reproduction is significant, and how sexual reproduction always results in a unique zygote.
2.List the functions of the reproductive systems.
3.Define the terms meiosis, DNA, somatic cells, gametes, diploid, haploid and zygote.
4.Name the common term for both the male and female gamete.
5.Distinguish between spermatogenesis and oogenesis.
6.Illustrate the steps involved in gamete formation (meiosis), explain the highlight(s) of each step, and explain any differences between male and female end-products.
7.Name the specific step of meiosis where homologous chromosomes are arranged together in tetrads (this is also called synapsis).
8.Compose a table comparing mitosis and meiosis in terms of time of DNA replication, number of divisions involved, number of daughter cells produced and their genetic composition, and the importance of each process.
9.Locate each of the following male reproductive organs on a diagram, discuss the structure of each organ, and name a major function for each organ:
testes, scrotum, epididymis, vas(ductus) deferens, seminal vesicle, ejaculatory duct, prostate gland, bulbourethral glands, urethra, and penis
10.Describe the microscopic structure of the testes and explain where spermatogenesis and androgen production occurs.
11.List and describe the sequence of events involved in spermatogenesis, beginning with a spermatogonium and ending with mature sperm cells. Be sure to keep track of chromosome number (2n = 46, or 1n = 23) and the number (i.e. 1, 2, or 4) of each cell type produced.
12.Name the location where sperm is stored.
