Related to Heterokonts: Heterokontophyta, Stramenopiles


Any of numerous mostly aquatic organisms in the group Heterokonta, having zoospores or other swimming cells usually with a pair of flagella, one of which has brush-like extensions, and whose photosynthetic members have a distinctive form of chlorophyll. Heterokonts include the brown algae, chrysophytes, diatoms, and oomycetes. Also called stramenopile.

[New Latin Heterokonta, taxon name : Greek hetero-, hetero- + Greek kontos, punting pole, goad (in reference to the pair of flagella); see kent- in Indo-European roots.]

They evolved from heterotrophic flagellates and photosynthetic algae, both categories belong to the heterokonts [8]; some of them left the zoosporic aquatic behavior and have been adapted to the terrestrial conditions to become amphibians and widespread inhabitants of soils and humus [4].
In addition, they are the source of the secondary plastids found in the numerous "brown" algal lineages, such as heterokonts, cryptophytes, and dinoflagellates, although it is unclear exactly how the secondary plastid of red algal origin was inherited among these groups (Keeling, 2013).
