They contain floridean starch as stored food. Red Algae Market Introduction Red Algae which is also known as Rhodophyta is one of the oldest group of Eukaryotic algae. The vast majority of red algae are multicellular, reaching a significant height (up to 2 m). Although they grow in both marine and fresh water, 98% of the 6,500 species of red algae are marine. Alternatively a single Class, the Rhodophyceae and two Subclasses, Bangiophycidae and Florideophycidae are used. Red marine algae, a type of marine algae are used for treating many diseases, and are believed to be capable of boosting the immune system. 1. The sea vegetable has been part of the diet of Characters of Red Algae: Red algae are defined as eukaryotic algae which possess chlorophyll a, phycobilins, floridean starch as food reserve, abundant phycocolloids (like agar, carrageenin, and funori) but lack flagellate cells. Red algae are any of the species of algae belonging to the taxonomic Division Rhodophyta. Different groups of algae have different and specific pigment composition. Algae are not a single taxonomic entity. Seaweed and Algal Q and A To what kingdom(s) do algae belong? ); Aglaophenia (tan hydroid across bottom portion). Red algae are considered as the most important source of many biologically active metabolites in comparison to the other algal class. This phylum contains over 7000 recognized species. Types of Common Red Algae 3. Red marine algae belong to the Rhodophyta class and have been part of the diet of Eastern civilizations for hundreds of years as they are rich in dietary fiber, protein, and vitamins. They have a red pigment, r-phycoerythrin.- Majority are marine especially in the warmer areas.- They occur in both well-lighted regions close to the surface of water and at great depths in oceans where relatively little light penetrates.- The red thalli of most of the red algae are multicellular. Of the more than 6,000 species of red algae, most are, not surprisingly, red, reddish, or purplish in color. The red algae are one of the most ancient groups of eukaryotic algae (fossils of Bangiomorpha pubescens, believed to be the oldest red alga, are 1.2 billions years old). 1.2.3.1. As is the case with many such products it was recommended for a variety of conditions but modern science does support a possible role in the treatment of viral infections such as those caused by the Herpes Simplex Virus—Type I (HSV-1).

Records indicate that red marine algae, a form of Traditional Chinese Medicine (TCM) dates back to approximately 300 B.C. Red algae are distinctive from other eukaryotic algae in that they lack flagella (ormotile cells of any kind) in their vegetative cells, spores, and gametes. 1.

ADVERTISEMENTS: In this article we will discuss about:- 1. ***Best viewed in Google Chrome and Mozilla firefox*** Maintained by BE4U They contain mannitol or laminarin as stored food. All algae get their energy from the sun from photosynthesis, but one thing that distinguishes red algae from other algae is that their cells lack flagella, the long, whiplike outgrowths from cells that are used for locomotion and sometimes serve a sensory function. They are characterized by the pigment phycoerythrin , which reflects red light and absorbs blue light. chlorophytes and rhodophytes - green and red algae), the Kingdom Chromista (e.g. Economic Importance. RHODOPHYTA Rhodophyta are cosmopolitan, found from the artic to the tropics. Molecular phylogeny (gene sequencing) and other characters show they belong to four kingdoms: Kingdom Plantae (e.g. Traditionally the red algae were divided into two Classes the Bangiophyceae and Florideophyceae. The red algae Kappaphycus and Betaphycus are now the most important sources of carrageenan, a commonly used ingredient in food, particuarly yoghurts, chocolate milk and repared puddings.Gracilaria, Gelidium, Pterocladia and other red algae are used in the manufacture of the all-important agar, used widely as a growth medium for microorganisms, and for food and biotechnological applications. Red Algae Brown algaeRed algae are grouped under the class Rhodophyceae. There are four thousand to six thousand species of red algae, and although some rhodophytes do inhabit freshwater (about fifty species), red algae are most common in tropical marine environments. Cytotoxic activity Red algae belong to the class Rhodophyceae under the phylum Rhodophyta which is one of the largest phylum of algae.
