Range of thallus structure in Algae
Range of thallus structure in Algae Algae show unicellular to multicellular, simple to complex, few micron (1×1.5) to very large sized thallus organisition (60 - 80 Mt). There are six types of algal thallus: (1) Unicelluler thallus : The thallus is made up of only one cell. The thallus may or may not be motile . (i) Motile form : They possess either rhizopod or flagella . In rhizopodal one the rigid cell wall is absent , so many amoeboid projections help in motility e.g.; Chrysamoeba of Chrysophyceae. In the members of Chlorophyceae , the flagella length equal,e.g., Chlamydomonas , but in case of Xanthophyceae or in Dinophyceae flagella length are unequal, e.g., Peridium. (ii) Non-motile form :In case of Spirulina of Cyanophyceae the only cell of the thallus is spiral but ,in case of Chorella , Gloeocapsa ,etc of Chlorophyceae the cell is spherical . (2) Multicellular colonial coenobium like thallus : A definite number of unicellular units c...
