The class Phaeophyceae is included within the division Heterokontophyta.[2] This name comes from the Greek word phaios meaning "brown" and phyton meaning plant.[3] They include some of the largest organisms in the sea, but some are small and fine in structure.

Classification

The Fucales include some of the more common littoral seaweeds and the members of the order have the typical seaweed construction: a holdfast, stipe, and lamina. The lamina is often much branched and may include gas-filled bladders. Growth is by division of the apical cells.

They are oogamous – fusion between the small male gamete and the large female gamete.
