The red green growth are a standout amongst the most antiquated gatherings of eukaryotic green growth (fossils of Bangiomorpha pubescens, accepted to be the most seasoned red alga, are 1.2 billions years old). A particular normal for this gathering is that they are the main ocean growth lacking flagella (and centrioles and different structures run of the mill of the flagellar device) at any phase of their life histories (Maggs et al., 2007. Their shading, which ranges from pink to brilliant red, purple or infrequently dim chestnut, is because of the nearness of colors called phycobilins. At present, around 6,000 red algal species are perceived. They have a mind boggling life history, which more often than not includes the shift of three eras (gametophyte, carposporophyte and tetrasporophyte).
Their sexual regenerative mechanical assembly is an exceptionally advanced structure, whose plan has been utilized for quite a while as the fundamental basis for scientific categorization at ordinal level. Sub-atomic information delivered in the most recent two decades have reformed the order of these life forms, which have a place with a solitary phylum, the Rhodophyta, subdivided in two subphyla (Cyanidiophytina and Rhodophytina), seven classes (Cyanidiophyceae, Bangiophyceae, Compsopogonophyceae, Florideophyceae, Porphyridiophyceae, Rhodellophyceae and Stylonematophyceae)
The red green growth demonstrate an extraordinary scope of morphological variety. The least complex structures comprise of single cells like Porphyridium or dainty fibers like Bangia. The propensity for extended edges is found in numerous genera, including probably the most awesome, for example, Delesseria Polyneura and Halymenia. A broad and financially vital sort with sharp edge like propensity is Porphyra yezoensis and comparative species are prevalently known with the japanese name of nori and have been utilized as sustenance for a long time in eastern Asia; they are the ocean growth utilized as wrap for sushi. In other red green growth, the body of the alga is framed by an outside layer which becomes joined to the rough base. An ordinary case is spoken to by types of the request Corallinales, in which the phone dividers amass calcium carbonate as aragonite, presenting to their body a strong and coriaceous consistence. Green growth of this request, for example, Lithophyllum, Lithothamnion (Figure 8) and Phymatolithon, look like pink or red calcified outside layers, which are exceptionally resistent to touching and mechanical dislodgement; they regularly blossom with extremely uncovered rough shores, where ocean growth with delicate tissues would be effortlessly unstuck by the brutality of the waves. Numerous different types of red ocean growth have a fanned plantlike shape and look like little hedges or trees. Species with this propensity incorporate numerous basic genera, for example, Chondrus, Gelidium (Figure 9), Gigartina, Gracilaria, Hypnea and Laurencia. Types of Eucheuma and Kappahycus are the most imperative wellspring of carrageenans (mixes generally utilized as a part of the nourishment business), and for this reason they are cultivated on substantial scale in tropical districts, particularly Philippines and Indonesia.
