Answer 1

Answer

1. A gamete is a haploid cell that combines with another haploid gamete during fertilization --- TRUE

2. Sperm mature and are stored in the epididymis. --- TRUE

3. In the first several weeks after fertilization, males and females are essentially the same --- TRUE

4. Genes on the X chromosome cause male organ formation. --- FALSE
- Genes on X chromosome cause formation of female organs while genes on Y chromosome cause formation of male organs.

5. Rapid growth occurs during puberty. --- TRUE

6. A sexually mature male produces hundreds of sperm each day --- FALSE
- Millions of sperms are produced by a sexually mature male each day.

7. Sperm are produced in the epididymis and become mature in the seminiferous tubules. --- FALSE
- Seminiferous tubule is the site for sperm production and epididymis is the site for sperm maturation.

8. When sperm “swim,” the tail rotates like a propeller. --- TRUE

9. Hundreds of billions of sperm are released with each ejaculation. --- FALSE
- Several millions of sperms are released with each ejaculation.

10. Spermatogenesis involves both mitosis and meiosis. --- TRUE

11. The part of the sperm called the tip produces enzymes that help the sperm penetrate an egg. --- FALSE
- The part of sperm that produces enzymes is called acrosome.
