Scientific classification or biological classification is how biologists group and categorize extinct and living species of organisms. ... Divisions Green algae land plants (embryophytes) non-vascular embryophytes Hepatophyta - liverworts Anthocerophyta - hornworts Bryophyta - mosses vascular plants (tracheophytes) seedless vascular plants Lycopodiophyta - clubmosses Equisetophyta - horsetails Pteridophyta - true ferns Psilotophyta - whisk ferns Ophioglossophyta - adderstongue ferns seed plants (spermatophytes) †Pteridospermatophyta - seed ferns Pinophyta - conifers Cycadophyta - cycads Ginkgophyta - ginkgo Gnetophyta - gnetae Magnoliophyta... Classes Chlorophyceae Ulvophyceae Trebouxiophyceae Prasinophyceae The Chlorophyta sensu stricto or chlorophytes, comprises most of what are commonly called green algae and includes most members of the grade of putatively ancestral scaly flagellates in Prasinophyceae plus members of Ulvophyceae, Trebouxiophyceae, Chlorophyceae, Pedinophyceae, Picocystophyceae, and unclassified Chlorophyta. ... Families Monostromataceae Ulvaceae Ulvellaceae Ulvales is an order of green algae. ...

The Ulvophyceae or Ulvophytes are class of green algae, distinguished mainly on the basis of ultrastructural morphology. The sea lettuce, Ulva, belongs here. Other well-known members include Ulothrix, Acetabularia, and Caulerpa. Divisions Chlorophyta Charophyta Streptophytina (Subdivision) The green algae are the large group of algae from which the embryophytes (higher plants) emerged. ... Species Ulva lactuca Ulva pertusa Ulva fasciata Ulva rigida Ulva pertusa Ulva linza and more at algaeBASE The sea lettuces comprise the genus Ulva, a group of edible green algae widely distributed along the coasts of the worlds oceans. ... Ulothrix is a genus of filamentous green algae, generally found in fresh and marine water. ... Acetabularia are giant (0. ... Binomial name Caulerpa taxifolia (M. Vahl) C. Agardh, 1817 Caulerpa taxifolia is a species of seaweed (a type of algae) that has been commonly used as ornamentation in aquarium installations around the world. ...


The Ulvophytes are diverse in their morphology and their habitat. Most are seaweeds such as those listed above. Others, such as Cladophora, Rhizoclonium and Pithophora live in fresh water and in some areas are considered weeds. Comparative anatomy is the study of similarities and differences in organisms. ... Habitat (from the Latin for it inhabits) is the place where a particular species lives and grows. ... Seaweed-covered rocks in the UK Biologists, specifically marine biologists, consider seaweed to be any of a large number of marine benthic algae that are multicellular, macrothallic, and thus differentiated from most algae that tend to be microscopic in size [1]. Many phycologists prefer the term marine macroalgae over seaweeds... Marimo (Japanese: 毬藻 marimo), also known as Cladophora ball in English, are a variety of algae found in some lakes of Japan, Iceland and Estonia. ... A weed is often an unwanted, usually wild or feral, plant. ...

Ulvophyceae, class Ulvophyceae is a member of :
Chlorophyta, division Chlorophyta — large division of chiefly freshwater eukaryotic algae that possess chlorophyll a and b, store food as starch, and cellulose cell walls; classes Chlorophyceae, Ulvophyceae, and Charophyceae; obviously ancestral to land plants

Ulvophyceae (179 words)
2005 indicate that Ulvophyceae as circumscribed here may be paraphyletic.
There is a lack of clear synapomorphies, i.e., defining characters, that set this group off from other green algae.
The characters below are either shared with some other green algae, or not present in all Ulvophyceae (see also Lewis and McCourt 2004).
