RED ALGAE(RHODOPHYTA)

                                          RED ALGAE(RHODOPHYTA)

Rhodophyta:

The scientific name of Red Algae is Rhodophyta and they belong to class Rhodopyhceae.They are two classes of red algal namely the Florideophceae and Bangiophy Bangiophyceae. Both Florideophyceae and Bangiophyceae comprise 99% of red algal diversity in marine and freshwater habitats.

 

                Red algae or Rhodophyta - It is a distinctave type of species that are mostly found in freshwater lake and are the oldest type of the eukaryotic algae.They are red in colour due to presence of a pigment called chlorophyll A, pycocyanin, and phycoerthrin.They are the member of the tribe Amansieae (Rhodomelaceae,Ceramiales,Rhodophyta),in which only Aneurianna and and Lenormandia Sonder have foliar blades.They are the distinctive type of species, mostly found in the deep freshwater bodies.

       

Examples of Red algae:

Ø Irish moss

Ø Dulse

Ø Laver(nori)

Ø Coralline algae

 

General Characteristics of Red algae:

Red algae are different from other Except For diatoms.Listed below are general           characteristics of Red Algae.                                       

 

Ø Lack of flagella and centrioles.

Ø Presence of photosynthetic pigements.

Ø Found both in marine and freshwater.

Ø They show biphasic or triphasic life cycle patterns.

Ø They are a multicellular,filament,blade structure.

Ø Stored food is in the form f starch and polymers of galactan sulphate.

Ø A pit connection (hole in the septum) is formed between two algal cell.

Ø Have a diffuse growth pattern-Apical growth ,complex oogamy (triphastic).

Ø These group of red algae is generally found in tropical marine location.

Ø The mood of nutrition may either be sarprophytic,parasitic or also epiphytic.

Ø There cell wall consist of cellulose and many different types of carbohydrates.

Ø Grow on solid surface independently or some times found attached to other algae.

Ø Presences of pit in the cell walls, through which cytoplasmic connection are maintained.

Ø The male sex organs are known as spermatangium and the female sex organ are called carpogania or procrap.

Ø Mode of Reproduction : It takes place by all there means vegetative,asexual and sexual mode of reproduction is by monospores and during the sexual mode of reproduction,they undergo altemation of generations.

 

 

      Different of Red algae to other algae:

       The only difference between the red algae and other algae is that the Red algae lack of flagella,the whip-like structure that help in locomotion and perform sensory functions.

 

       Different pigments present in algae:

        The different pigments present in red algae are:

 

Ø Red phycoerythrin

Ø Blue phycoerythrin

Ø Zeaxanthin

Ø Caroteans

Ø Lutein

 

 

       Uses of Red Algae:

                    Red algae has great ecological importance.They form a vital part of the food                      chai and are also involved in producing about 40 to 60 per cent of the tota                         global oxygen for both terrestrial habitat and other aquatic habitats.Listed                       below are a few ecological and commercial important of red algae.

 

Ø Algae provide natural food for fish and other aquatic animals.

Ø Red algae is the most important commercial food in japan and region of north Atlantic.

Ø Agar or agar-agar a,jelly-like substance which is used in puddings, dairy toppings and other instant food products is extracted from Red algae.

Ø Red algae are used are as the source of food for thousand years as they are high vitamins,minerals, a rich source of calcium ,magnesium, and antioxidants.

Ø They are source of the dietary fibre as they have ability to promote healthy circulation, lower bad cholesterol and regulate blood sugar levels.

Ø They are also involved in nourishing your skin, boosting the immune system and contributing to bone of health.

 

 

Importance of Red algae:

   Red algae form an important part of ecosystem and are consumed by various organisms such as crustaceans, fish, worms and even humans.Red algae are also that is used as a food additive.they are rich calcium and also used in vitamin supplements.

 

 

 Red algae found:

 Red algae are found in coral reefs and tide pools.They have the ability to survive at grater depth then other algae because the pigment phycoerthrin absorbs the blue light that can penetrate deeper than any other light wave.This allows to carry out photosynthesis at greater depth.

Ozone water purification

OZONE (O3)  WATER         PURIFICATION  INTRODUCTION It is well acknowledged that ozone water purification is the most efficient   FDA-approved technique for getting rid of a variety of pollutants that are frequently present in water. Ozone, often known as O3, is a very potent oxidant since it is a molecule made up of three oxygen atoms. Because of this property, ozone is significantly more powerful than chlorine at rendering pesticides, fungus, organic compounds, pollutants, and viruses inactive. An ozone generator is used to create ozone gas, which is subsequently dissolved into the water to carry out the operation. When ozone is present, it starts to oxidize and decompose dangerous materials including germs, viruses, and organic stuff. By eliminating additional pollutants and chlorine byproducts, this oxidation process not only gets rid of these contaminants but also makes the water taste and smell better overall. The capacity of ozone water pu...

pH and microbes relationship easy understand formate

 p H AND MICROBES RELATIONSHIP pH:      The ‘H’ in pH is the elemental symbol for hydrogen. The ‘p’ can refer to different things in different languages, but the ‘pH’ is most commonly said to mean ‘power of hydrogen   pH is a measure of   hydrogen   ion   concentration ,   a measure of the   acidity   or   alkalinity   of a   solution . The pH scale usually ranges from 0 to 14. In simple terms, pH is a scale from 1 to 14 that measures the acidity or alkalinity of a liquid. In the middle of the scale is pure distilled water, with a neutral pH of 7. Anything with a pH below 7 is an acid, and anything with a pH above 7 is an alkali, or base. pH and Microbes relationship: pH correlates strongly with microbial communities across a wide range of biogeochemical conditions  and p H also induce significant responses of metabolic activities of natural communities . In soils, pH is usually indicated as the most important dr...

Marine Food Chain - Difference Between Phytoplankton and Zooplankton

Image
MARINE FOOD CHAIN Marine Food Chain A food chain illustrates the source of food for every living creature as well as the transfer of energy from one living thing to another. Large animals are at the end of food chains, which start with plants. A single route that links a producer with many tiers of consumers is called a food chain.Energy is necessary for all living things to operate. To do the tasks necessary for existence, they must use energy. Although they are not able to produce energy, living creatures are able to change one type of energy into another. The producers initiate the energy transformation cycle in the water. Producers convert energy from chemicals or the sun into organic molecules that are used as food.Microscopic plants called phytoplankton and tiny critters called zooplanktoneat plants. Lobsters and other invertebrates consume zooplankton. The invertebrate is eaten by fish and other vertebrates like cod.The largest animal is not the end of the food webs. In the natu...
