Similar to pigmentation in algae, the distributional difference in reserved food is also in the classification of different algal groups. Following are the important characteristics of fungi: Fungi are eukaryotic, non-vascular, non-motile and heterotrophic organisms. For instance, algae can photosynthesize like plants, and they possess specialized structures and cell-organelles, like centrioles and flagella, found only in animals. Based on type of the cell, algae can be grouped basically into two major assemblages prokaryotic and eukaryotic algae There are four distinct groups within the algae − Group 1 Prokaryotic algae include two divisions: Cyanobacteria and Prochlorophyta.. − Group 2 Eukaryotic algae with … In general algae can be referred to as plant-like organisms that are usually photosynthetic and aquatic, but do not have true roots, stems, leaves, vascular tissue and have simple reproductive structures.

Algae - Algae - Classification of algae: The classification of algae into taxonomic groups is based upon the same rules that are used for the classification of land plants, but the organization of groups of algae above the order level has changed substantially since 1960. Certain intertidal species such as the ulva, or sea lettuce, can tolerate a range of temperatures and survive drying at low tide. Yeasts are unicellular fungi that do not produce hyphae.

Algae: General Characters PPT (General Characteristics of Algae PPT) What are algae? All algal cells have a definitive cell wall that is thin in some species, but in others, like diatoms, the cell wall is impregnated with silica, which makes it rigid and hard.
