Batrachospermaceae

From Wikipedia, the free encyclopedia

Batrachospermaceae[1] is a family of freshwater red algae (Rhodophyta), a group of reddish plants found in rivers and streams. These algae have a distinct life cycle called the "Lemanea-type," starting with small reproductive cells known as carpospores that grow into a form called chantransia. This leads to a sporophyte phase, during which a process called meiosis—where cells divide to create new reproductive cells—takes place in a specialized cell at the filament’s tip, known as the apical cell, responsible for growth. This division results in the gametophyte, the stage of the algae that produces reproductive structures.[2] Various genera within this family are listed in the table below.

The structure of Batrachospermaceae is remarkable for its organization: each filament, or thread-like strand, grows from a single apical cell, a feature termed uniaxial.[3] Inside their cells, they have pit connections—structures with two cap layers, one of which is enlarged—that help maintain strength and linkage between cells.[2] These characteristics make Batrachospermaceae a notable group within the study of freshwater algae.
