Dasycladales

Acetabularia is a genus of green algae in the family Polyphysaceae. Typically found in subtropical waters, Acetabularia is a single-celled organism, but gigantic in size and complex in form, making it an excellent model organism for studying cell biology. In form, the mature Acetabularia resembles the round leaves of a nasturtium, is tall and has three anatomical parts: a bottom rhizoid that resembles a set of short roots; a long stalk in the middle; and a top umbrella of branches that may fuse into a cap. Unlike other giant unicellular organisms, which are multinucleate, members of this genus

Dasycladales is an order of large unicellular green algae in the class Ulvophyceae. It contains two extant families, the Dasycladaceae and the Polyphysaceae.

The Polyphysaceae is a taxonomic family of green algae, one of three families in the order Dasycladales. For single-celled organisms, they are huge, growing to nearly a foot long in some cases.
