ALGAE

According to five king dome classifiction system whish was suggested by Ropert wittaker in the 5 kingdoms were ( monera, protista, plants,animals,fungi). So algae included in kingdome monera wich contains cyanophyta or blue green algae and kingdom protista which contains all other groups of algae. Position of algae:

Classification of algal division based on: 1-Biochemical criteria: A-pigments. B-storage products. C- cell wall composition. 2-Morphological criteria. 3-genetic differences. 4-many can survive desiccation for several years
