Mucilage secretions of moving diatoms

  • Published:
Protoplasma Aims and scope Submit manuscript

Summary

The raphes of a moving diatom are filled with mucilage strands which are perpendicular to the slit and protrude from the external raphe fissure. The distal ends of the strands are capable of adhering to the substratum.Navicula cuspidata moves with only the posterior half of the cell adhered; the anterior is elevated from the substratum. The species studied left no apparent mucilage trails.
