"Seaweed" lacks a formal definition, but seaweed generally lives in the ocean and is visible to the naked eye. The term refers to both flowering plants submerged in the ocean, like eelgrass, as well as larger marine algae. Generally, it is one of several groups of multicellular algae; red, green and brown.

Chlorella is a genus of about thirteen species of single-celled or colonial green algae of the division Chlorophyta. The cells are spherical in shape, about 2 to 10 μm in diameter, and are without flagella. Their chloroplasts contain the green photosynthetic pigments chlorophyll-a and -b.
The algae of this paraphyletic group "Charophyta" were previously included in Chlorophyta, so green algae and Chlorophyta in this definition were synonyms. As the green algae clades get further resolved, the embryophytes, which are a deep charophyte branch, are included in "algae", "green algae" and "Charophytes", or these terms are replaced by ...
Caulerpa is a genus of seaweeds in the family Caulerpaceae (among the green algae).They are unusual because they consist of only one cell with many nuclei, making them among the biggest single cells in the world.
Green algae: These groups have green chloroplasts containing chlorophylls a and b. [22] Their chloroplasts are surrounded by four and three membranes, respectively, and were probably retained from ingested green algae. Chlorarachniophytes, which belong to the phylum Cercozoa, contain a small nucleomorph, which is a relict of the algae's nucleus.
Although most contemporary ulvophytes are marine macroalgae , ancestral ulvophytes may have been freshwater, unicellular green algae. Molecular phylogenetic evidence suggests that macroscopic growth was achieved independently in the various major lineages of Ulvophyceae ( Ulvales - Ulotrichales , Trentepohliales , Cladophorales , Bryopsidales ...
Ulva australis, the southern sea lettuce, is a species of bright green coloured seaweed in the family Ulvaceae that can be found in waters around Australia and was first described by Swedish botanist Johan Erhard Areschoug. It is an edible green algae, although sometimes designated as a seaweed. [1]
Caulerpa lentillifera or sea grape is a species of ulvophyte green algae from coastal regions in the Asia-Pacific. This seaweed is one of the favored species of edible Caulerpa due to its soft and succulent texture. It is traditionally eaten in the cuisines of Southeast Asia, Oceania, and East Asia.
