- Fern sperm release
- Fern spores germinate into haploid fern gametophytes; small plants only a few millimeters in diameter. These gametophytes produce sperm by mitosis in small sacs called antheridia. When placed in water, the antheridium opens up, and the sperm are released. In these sequences, the release of sperm is visible, including a single sperm being released from an antheridium
