	Rhipiliopsis ''Rhipiliopsis'' is a genus of green algae in the family Rhipiliaceae Rhipiliaceae is a family of green algae in the order Bryopsidales Bryopsidales is an order of green algae, in the class Ulvophyceae. Characteristics The thallus is filamentous and much branched and may be packed into a mass. It is coenocytic .... ''Johnson-sea-linkia'' is a synonym. Morphology According to Algaebase as described by Kraft (1986), the thallus height ranges from less than 5 mm to above 7 cm, non-calcified and the prostrate rhizome or digitate processes within the substratum gives rise to the blade and stalk system. The fronds are monostromatic or polystromatic having irregularly lanceolate or regularly to excentrically peltate, with siphons dichotomously branched and generally equally constricted above dichotomy. A somewhat differentiated cortex was observed on upper and lower surfaces of fronds and scattered spines occur on blade siphons for the two species with thickest blade. ...

	Bryopsidales Bryopsidales is an order of green algae, in the class Ulvophyceae. Characteristics The thallus is filamentous and much branched and may be packed into a mass. It is coenocytic, having multi-nucleate cells consisting of cytoplasm contained within a cylindrical cell wall. There are no septae and the many discoid chloroplasts, nuclei and other organelles are free to move through the organism. The whole organism may consist of a single cell and in the genus ''Caulerpa'' this may be several metres across. In the genus '' Halimeda'', whole seabed meadows may consist of an individual, single-celled organism connected by filamentous threads running through the substrate. Reproduction Propagation is normally vegetative from small fragments which grow into new individuals. Under certain conditions sexual reproduction occurs in a process called holocarpy. Almost all of the cytoplasm in the thallus is converted into biflagellate gametes, which are discharged into the sea through papillae ...

picture info	Green Algae The green algae (singular: green alga) are a group consisting of the Prasinodermophyta and its unnamed sister which contains the Chlorophyta and Charophyta/Streptophyta. The land plants (Embryophytes) have emerged deep in the Charophyte alga as sister of the Zygnematophyceae. Since the realization that the Embryophytes emerged within the green algae, some authors are starting to properly include them. The completed clade that includes both green algae and embryophytes is monophyletic and is referred to as the clade Viridiplantae and as the kingdom Plantae. The green algae include unicellular and colonial flagellates, most with two flagella per cell, as well as various colonial, coccoid and filamentous forms, and macroscopic, multicellular seaweeds. There are about 22,000 species of green algae. Many species live most of their lives as single cells, while other species form coenobia (colonies), long filaments, or highly differentiated macroscopic seaweeds. A few other organi ...
