Most centric and araphid pennate diatoms are nonmotile, and their relatively dense cell walls cause them to readily sink. Planktonic forms in open water usually rely on turbulent mixing of the upper layers of the oceanic waters by the wind to keep them suspended in sunlit surface waters. Many planktonic diatoms have also evolved features that slow their sinking rate, such as spine… WebThrough the raphe, the living diatom secretes mucilage, with which it may attach to a substrate or move by gliding over the substrate. Within their silica walls, diatoms show a typical level of eukaryote organization. Living diatoms contain several chloroplasts, where photosynthesis takes place.
