algae are classified into three main classes (Chlorophyceae, Phaeophyceae, and Rhodophyceae) primarily depending on the type of pigment possessed and the type of stored food . The classes are commonly known as Green, Brown, and Red algae, respectively, based on the colour imparted by their major pigments (e.g., Chlorophyll a and b, Fucoxanthin, Phycoerythrin) , , . While stored food and cell wall composition also vary, the presence of specific pigments is the most fundamental character used for their primary grouping.
