How does diatom reproduce

Diatoms have a nucleus, cytoplasm, vacuoles, and chromatoplasts as cell components. The silicon wall is porous with different designs at various places for passage of gases and nutrients within the cell. These algae are classified into pinnate and centric groups. The ones belonging to the latter group are … See more This is the primary form of reproduction, and it occurs by binary fission. In this process, the DNA undergoes replication that causes the chromosomes to divide into … See more Diatoms are non-motile organisms, and therefore the sperms have flagella.
