Algae - Algae - Photosynthesis and light-absorbing pigments: Photosynthesis is the process by which light energy is converted to chemical energy whereby carbon dioxide and water are converted into organic molecules. Classification based on Nutrition (How they Obtain Energy) There are three main categories based on nutrition.  Most of the algae are autotrophic characterized by their ability to use Class 2 Hyphochytridiomycetes- Motile cells with a single tinsel flagellum inserted at the anterior end.

Concepts of Botany Algae (PDF 21P) This note contains explanation of algae, structure of alage and its classification. The process occurs in almost all algae, and in fact much of what is known about photosynthesis was first discovered by studying the green alga Chlorella. For example, some phycologists place the classes Bacillariophyceae, Phaeophyceae, and Xanthophyceae in the division Chromophyta, whereas others place each class in separate divisions: Bacillariophyta, Phaeophyta, and Xanthophyta.  The algae includes both the microscopic unicellular to macroscopic In India, the division is represented by 98 genera and about 833 species.

Reproduction 6. Algae is used as a key ingredient in various food products. Now let's study about the biological classification. 1980 - Lee used fine structural aspects of organelles such as chloroplast, ER, flagellum, eyespot and nucleus to classify the algae into 6 divisions and 15 classes. These are the most ancient bacteria found in the most extreme habitats such as salty area (halophiles), hot springs (thermoacidophiles) and marshy areas (methanogens). Class 3 Plasmodiophoromycetes- Parasitic fungi producing biflagellate motile cells with both the flagella of whiplash type inserted at the anterior end. They classified fungi based on both the phases (i.e., haploid and diploid) of life cycle; structure of thallus and organs of fructifications. Division-level classification, as with kingdom-level classification, is tenuous for algae. recognizes two subphyla on the basis of organs of locomotion and 5 classes as follows: Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising.

The latter have a metabolism that is similar to that of the bacteria found in activated sludge and in trickling filters (see biomass used in wastewater purification. Zoospore, aplanospore, hypnospore, tetraspore, autospore, akinetes etc are the important spore types in algae. In the bacteria kingdom, figure 1, autotrophic organisms (chemotrophic bacteria, see water and cell metabolism, nitrogen cycle, sulphur cycle and iron and manganese cycle) exist alongside heterotrophic organisms (usually scavengers). These acids contain even number of carbon atoms linked together in long chains which are in general un-branched. Characteristics. the carbon-di-oxide as a carbon source and light as an energy source.

INTRODUCTION • The general term "algae" includes prokaryotic organisms — cyanobacteria, also known as blue-green algae — as well as eukaryotic organisms (all other algal species). Cyanobacteria is also composed of a wide variety of bacteria species of different shapes are sizes that can be found in different habitats in the environment. 1.1 ClASSIFICAtIon The classification of algae is complex and somewhat controversial, especially concerning the blue-green algae (Cyanobacteria), which are sometimes known as blue-green bacteria or Cyanophyta and sometimes included in the Chlorophyta. AlgaeAn Overview 2. Algae: Occurrence, types, classification, economic importance Topics covered: Introduction to algae. • According to Dr.F.E.Fritsch (1935,1944,1945) the algae have been divided into following eleven classes 1)Chlorophyceae 7)Chloromonadineae 2)Xanthophyceae 8)Euglenophyceae or 3)Chrysophyceae Euiglinieae 4)Bacillariophyceae 9)Phaeophyceae 5)Cryptophyceae 10)Rhodophyceae 6)Dinophyceae 11)Myxophyceae algae and cyanobacteria.

Also called Rhodophyta, it is a distinctive species found in marine as well as freshwater ecosystems. Members of the class Myxophyceae (Cyanophyceae) are commonly known as blue green algae. However, since blue-green algae are prokaryotes, they are not currently included under algae (because all algae are classified as eukaryotic organisms). DIVISION CLASS CHLOROPHYTA CHLOROPHYCEAE , CHAROPHYCEAE EULENOPHYTA EULENOPHYCEAE PYRROPHYTA CRYPTOPHYCEAE, DESMOPHYCEAE, DINOPHYCEAE CHRYSOPHYTA XANTHOPHYCEAE, CHRYSOPHYACEAE, BACILLARIOPHYCEAE PHAEOPHYTA ISOGENERATAE, HETEROGENERATAE, CYCLOSPORAE CYANOPHYTA MYXOPHYCEAE … Customer Code: Creating a Company Customers Love, Be A Great Product Leader (Amplify, Oct 2019), Trillion Dollar Coach Book (Bill Campbell). Ø Different groups of algae have different pigment composition. Linnaeus divided his order Cryptogamia into four suborders, i.e., (1) Filices (pteridophytes), (2) Musci (mosses and leafy liverworts), (3) Algae, (algae, lichens and thallose liverworts), (4) Fungi. Subphylum IV: Ciliophora. It is also called as Algae-Fungi because most of the characteristics of them are similar to algae like Vaucheria. Now let's study about the biological classification. The substance can either be used as an additive or can act as a thickener in many types of food products. Fungi: molds, yeasts, mushrooms, rusts, andungi smuts. Classifications.

The fact is, algae need not to be evoluated to sexual plant while migrating from water to land ( and at the same time, there is no strong evidence in it’s court also). Parasites or decomposers. Kingdom Monera is classified into three sub-kingdoms- Archaebacteria, Eubacteria, and Cyanobacteria. They divi­ded the fungi into four classes are: 1. Chlorophyceae is the universal one that is proposed and expected widely as the origin of bryophytes. Nothing could be further from the truth. Algae - Algae - Ecological and commercial importance: Algae form organic food molecules from carbon dioxide and water through the process of photosynthesis, in which they capture energy from sunlight.
