WebJun 16, 2024 · Diatoms primarily reproduce asexually by binary fission, similar to prokaryotes. During binary fission, the two valves of the frustule are separated and each new cell forms a new valve inside the old one. However, the new valve is always smaller. WebIn diatom sexual reproduction, you have some cells that form an egg. The female cells form this egg, and you have other cells that go through meiosis and form a bunch of flagellated little sperm cells. Those gametes will swim over and fertilize that egg cell of the females, and once that's fertilized, it's forming what's called an auxospore.
