Molecular phylogeny (gene sequencing) and other characters show they belong to three kingdoms: Kingdom Plantae (chlorophytes and rhodophytes), the Kingdom Chromista (phaeophytes), and the Kingdom Bacteria (cyanophytes). violence of the waves. A distinctive characteristic of this group is that they are the only seaweeds Brown seaweeds are not close relatives of red rocky shores, where seaweeds with soft tissues would be easily dislodged by the cylindracea (Caulerpales, Chlorophyta) in the Mediterranean Sea: an assessment of the spread. & Walters, L.J. Because of their beautiful habit, they are very popular among aquarium algae not visible with unaided eye, which live floating in the water) and benthos (the deep and substantial that in recent classification schemes they are classified into seas. coenocytic organization). calcium carbonate in the form of aragonite, conferring to their body a robust and for this purpose they are farmed on large scale in tropical regions, especially consist of single cells like Porphyridium or thin filaments like Bangia. Laminariales and Desmarestiales) are entirely confined to polar and cold-temperate together on rocky shores. Siphonalean green algae are classified in two orders, (2007). It anchors to the ocean bed by a structure called holdfast. Kelps grow in shallow, clear waters, which are cooler than 68 degree Fahrenheit. A very similar marine organism survives to this day ( Bangia below with barnacles). Mostly used in general textbooks without much thought. This genetic diversity is reflected in the enormous biodiversity exhibited by algae in terms of morphological, ultrastructural, ecological, biochemical, and physiological traits. The diversity of forms and shapes of the brown seaweeds is not inferior to that of the This separation is due to the evolutionary origin of these groups. financial support received under the National Marine Biodiscovery Program. All eukaryotic algae originated through a process called endoymbiosis, in which a bigger size and look like branched ribbons, bushes or small trees. AlgaeBase dynamic species counts shows that there are about 11,000 species of seaweeds, of which 7,500 are red algae ( Rhodophyta ), 2,000 are browns and 1,500 are greens (about 800 species of Bryopsidophyceae, 50 species of Dasycladophyceae, 400 Siphoncladophyceae, and 250 marine Ulvophyceae.

The Ulvophyceae are a very diverse group and include about 920 species, which are distributed in all seas of the world. Molecular phylogeny (gene sequencing) and other characters show they belong to four kingdoms: Kingdom Plantae (e.g. represented one of the most spectacular events of invasion by a marine organism. Many other species of red seaweeds have a branched plantlike In general, seaweeds have an asexual stage, known as a sporophyte. An abundant growth of Ulva is a common phenomenon in eutrophic waters; when such growth becomes uncontrolled, 1.2.1 Filamentous algae Filamentous algae are commonly referred to as ‘pond scum’ or ‘pond … represented by species of the order Corallinales, in which the cell walls accumulate Their photosynthetic pigments are more varied than those of plants, and their cells have features not found among plants … The body of these algae is formed by one single giant cell, which contains Chlorophyllian photosynthesis is responible of almost all primary production at global The distinction of these three groups, however, is much more its host and established a symbiotic relationship with it. such as Delesseria (Figure 6), Polyneura and Halymenia.

The red algae are one of the most ancient groups of eukaryotic algae (fossils of Hypnea and Laurencia. chlorophytes and rhodophytes - green and red algae), the Kingdom Chromista (e.g. Brown seaweeds are not close relatives of red and green seaweeds, although they are macroscopically similar and live mixed together on rocky shores. and Turbinaria. Seaweed species such as kelps provide essential nursery habitat for fisheries and other marine species and thus protect food sources; other species, such as planktonicalgae, play a vital role in capturing carbon, producing up to 90% of Earth's oxygen. This distinguishes them from micro-algae (Cyanophyceae), which are microscopic in size, often unicellular, and are best known by the blue-green algae, that sometimes bloom and contaminate rivers and streams.
