First of all, diatoms can reproduce asexually. Reproducing asexually is the basic method of how diatoms reproduce. Diatoms have a distinctive mode of reproduction called “shrinking division,” which is used in asexual reproduction. After cell division, the two valves that encase the diatom separate.

WebThe main characteristics of diatoms are as follows: They have a cell wall that surrounds the entire cell as if it were an external skeleton. Their cell wall is formed by silica. They have little or no ability to move so they are carried away by different currents and surfaces. They reproduce by binary division, each new cell has one leaflet ... WebFor example, some brown alga (Phaeophyceae) reproduce by producing multi-flagellated male and female gametes that recombine to form the diploid sporangia. Zoids are primarily found in some protists, diatoms, green alga, brown alga, non-vascular plants, and a few vascular plants (ferns, cycads, and Ginkgo biloba).
