Answer the following question given this paragraph: Gametogenesis may differ between males and females. Male gametes are called sperm . Female gametes are called eggs . In human males, for example, the process that produces mature sperm cells is called spermatogenesis . During this process, sperm cells grow a tail and gain the ability to "swim," like the human sperm cell shown in Figure below . In human females, the process that produces mature eggs is called oogenesis . Just one egg is produced from the four haploid cells that result from meiosis. The single egg is a very large cell, as you can see from the human egg in Figure below . Q: What are the male gametes called? Choices: - cytoplasm - pollen - urea - sperm A:
sperm
