How does diatom reproduce
WebDiatoms generally reproduce asexually by mitosis. The two frustules separate, each with a nucleus and cytoplasm. Each daughter constructs a new frustule. The newly constructed frustule is always the bottom (smaller one). WebFeb 23, 2024 · During reproduction, usually by cell division, the overlapping shell halves separate, and each secretes a (usually) smaller bottom half. …

WebMay 3, 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. If diatoms only reproduce in this way, it results in a continual decrease in average size.
