1. A gamete is a mature haploid sex cell (sperm or egg) that can unite with another gamete of the opposite sex to form a zygote.
2. Male gamete: Sperm; Female gamete: Egg (or ovum).
3. Scrotum.
4. Sperm production requires a temperature slightly lower than the body's core temperature; 35°C is optimal for spermatogenesis, and higher temperatures can impair sperm development.
5. (Top to bottom, left to right based on typical diagram labeling)
- Bladder
- Vas deferens
- Seminal vesicle
- Prostate gland
- Urethra
- Penis
- Testis
- Epididymis
- Scrotum
6. Testosterone is produced in the Leydig cells (interstitial cells) of the testes.
7. The epididymis stores and transports sperm from the testes, allowing them to mature and gain motility.
8. A vasectomy is a surgical procedure for male sterilization in which the vas deferens is cut and sealed to prevent sperm from entering the semen.
