For ten points, name these flagellated cells that are produced in the testes and can fertilize eggs.
In humans, the environment in which these cells must develop is carefully regulated by the cremaster muscle, and Sertoli cells provide nutrients to these cells before they mature. In some plants, these cells are produced by the antheridia. These cells cause a release of calcium ions that prompts cortical granules to fuse with the perivitelline space, and contain a vesicle called an (*) acrosome that allows them to degrade part of the zona pellucida. In humans they travel through the vas deferens after maturing in the epididymis under the cooler temperatures provided by the scrotum.
