Ochrophyta

Nannochloropsis oculata, from SBAE Industries NV.


Belongs within: Heterokonta.
Contains: Diatomeae, Marista, Chrysomonadea.

The Ochrophyta includes the photosynthetic heterokonts (golden and brown algae, etc.) and their secondarily non-photosynthetic deerivatives. They possess either a single ciliary transition region helix (Phaeista) or lack this helix entirely (Khakista) (Cavalier-Smith & Chao 2006).
