Polysiphonia est un genre d’algues rouges de la famille des Rhodomelaceae. Son appareil végétatif est un cladothalle à croissance télomique (c'est à dire par l'extrémité). Cette croissance est orientée par la présence de nœud et d'entre-nœud.

Learn vocabulary, terms, and more with flashcards, games, and other study tools. Red algae have a haplodiplontic (alternation of generations) life cycle that has an extra diploid stage: the carposporophyte. Polysiphonia is the model organism for the Rhodophyta life cycle. The gametophytes of Polysiphonia are isomorphic (iso- meaning same, morph- meaning form), meaning they have the same basic morphology.

The three different stages are distinguishable only by microscopic examination of the reproductive structures. In the life cycle of Polysiphonia, and many other red algae, there are separate male and female gametophytes, carposporophytes that develop on the female gametophytes, and separate tetrasporophytes.

However, it was not until the late 1980s that Labyrinthula was conclusively linked to the acute seagrass declines The Newark Supergroup (Late Triassic - Early Jurassic) of eastern North America is world-famous for it's fossil footprint assemblages.
