CHARACTERSTIC OF ALGE

                                                     FRITCH CLASSIFICATION

Acroding to fritch classification the alge  are different types

Such as- (1) chlorophyceae

                 (2) rhodophyceae

                 (3) cyanophyceae

                 (4) xyntophceae

                 (5) pheophyceae

                 (6) basilariophyceae

                 (7) euglinophyceae

                (8) chloromonadine

CHLOROPHYCEAE

·        These are green alge

·        The colour of alge green due to presence of cholorophil A & B.

·        Along with the chlorophyll A & B xyntophill and beta charotin is present.

·        The reserve food material is starch.

·        Flajela are present.

·        Eg- volvox,eulothrix etc

RHODOPHYCEAE

·        These are mainly merain water alge  few are fresh water alge.

·        These are red colour alge due to presence of r-phycoerithrin & r-phycociamine

·        The reserve food material is florebean starch.

·        Flejela are absent.

·        These are multicellular.

·        Eg – btrachospermom.

CYANOPHYCEAE

·        These are fresh water alge.

·        The colour of alge blue green .

·        The colour of alge blue green due to presence cphycocemine and xynthophil pigment.

·        Flajela are absent

·        The reserved food material is  phycocimine starch

·        Eg-nostoc anabena

XYNTHOPHYCEAE

·        These are yellow green alge.

·        These are yellow green due to presence xynthophill & chlorophyll and beta charotin and present.

·        The resev food material is oil.

·        Flajela are present and it is heterocynet.

·        Reproduction takes place by sexual, asexual & vegetative method

·        Eg

PHEOPHYCEAE

·        The alge are brown in colour.

·        These are brown colour alge due  to presence of fucoxanthin.

·        Along with fucoxanthin xynthophill, cholorophill A & C charotin are present.

·        The reserved food material is maniter and laminaria.

·        Flajela are present.

·        Eg-

BASILARIOPHYCEAE

·        The member of basilariophyceae is called diatoms.

·        Beside the diatoms chlorophyll A & C xynthophills and charotin are present.

·        The reserve food material is fat and oil.

·        These are sily in flajelum.

·        These are non motail in nature.

·        Reproduction takes place by mix of spore.

·        Eg-

EUGLINOPHYCEAE

·        These fresh water alge.

·        Body are alongated.

·        Cell wall is absent in the cell.

·        The reserved food material is polysacharaids.

·        The flajela are absent.

·        Eg

CHLOROMONADINE

·        The are bright in colour.

·        The pigment is present in the member of chloromonadine in xynthofill.

·        The reserved food material is oil.

·        The flajea are present.

·        The case of choloromonadine in the sexual reproduction takes place.

·        Eg – vaucheria.
