Dictyochales

Dictyocha speculum

The Dictyochophyceae are a class of single-celled organisms from the group of Stramenopilen.

Features

The representatives are unicellular or colony-forming flagellates or amoebae. The cells are naked, wear organic scales or a silicate skeleton. Plastids are present in some representatives and then have belt slats. The plastid DNA has a grain -type Genophor. Ocelli absent.

Among the plastid pigments include chlorophylls a and c1, 2, fucoxanthin, Diatoxanthin and Diadinoxanthin.

Enthusiast cells usually possess a scourge that is directed to the front and three-piece tubular hair wearing.

The kinetosomes are pressed onto the cell nucleus. Microtubular or fibrillar kinetosomes roots are missing.

System

The Synurales are one of the groups of Stramenopile. To them, the following orders are counted:

• Dictyochales missing with silicate skeleton in at least one life stage, plastids.
• Pedinellales: flagellates, naked, with organic scales or Lorica; Plastids present or absent.
• Rhizochromulinales: vegetative cells are amoeboid, flagellated zoospores; Plastids present.
