The plant body is commonly differentiated to form stem and leaf-like structures. Phaeophyceae – Also called as brown algae, they are predominantly marine. The taxonomy of the group is contentious, and the class is sometimes placed in its own division, Charophyta. Order. Approximately 3600 species are known, mainly from freshwater and to a lesser extent terrestrial habitats. Classifications. There is three main Algae classification: Chlorophyceae – These are called green algae, due to the presence of pigments chlorophyll a and b. Green Algae: Phylum Chlorophyta • Chlorophyll in both green algae and plants are not normally masked by other pigments • Land plants are believed to have evolved from green algae; considered by many taxonomists as belonging to Kingdom Plantae! 6. Classes of Chlorophyta 1. The pigments, chlorophyll-a, chlorophyll-b, carotene and xanthophyll are present in them. — J. Phycol.19, 248–251.

Examples of taxonomic ranks are species, genus, family, order, class, phylum, kingdom, domain, etc. These divisions are based on the following factors: (a) Major photosynthetic pigments present (b) Form of stored food (c) Cell wall composition They are usually grass green in colour due to the dominance of pigments i.e.chlorophyll a and b. Phaeophyceae: The members of Phaeophyceae are commonly called brown algae. Classification of Chlorophyceae (Green Algae): 1. The taxonomy of Volvocales (Chlorophyceae, Chlorophyta) was traditionally based solely on morphological characteristics.

The Chlorophyceae are a large and important group of freshwater green algae. Volvox is a microorganism that lives in the form of a colony for mutual benefit. Fritsch (1944-45) classified algae into 11 classes in his book 'Structure and Reproduction of Algae' based on the following characteristics. Chlorophyta reproduce both sexually and asexually, but usually sexually. chlamydomonas but in certain member of chlorophyceae xanthophyceae, chrysophyceae, this state of existence becomes permanent. Many types of chlorophyceae have a wall ornamentation type that is useful in classification. They include some of the most common species, as well as many members that are important both ecologically and scientifically.

[In a note added in proof, an alternative classification is presented for the class Chlorophyceae:] Class Chlamydophyceae (orders Volvocales, Chlorococcales, Chaetophorales) Class Oedogoniophyceae (order Oedogoniales) Class Chlorophyceae (order Chlorellales) Reviers (2002-2003) Reviers, B. de (2002-2003). Chlorophyceae . The class Chlorophyceae is commonly called as green algae. Algae are the aquatic eukaryotic organisms that have chlorophyll and carry out oxygen-producing photosynthesis. Botrydium. A revision of the classification of the green algae. However, because recent molecular phylogeny largely contradicts the traditional subordinal and familial classifications, no classification system has yet been established that describes the subdivision of Volvocales in a manner consistent with the phylogenetic relationships. McManus, H.A., K. Fučíková, P.O. ... Nomenclature and Classification … New Phytologist 1: 17–24, 47–48, 67–72, 89–96, 114–120, 133–144, 163–168, 189–192, 213–220, 238–244. Class Chlorophyceae Primarily freshwater; includes Chlamydomonas, Chlorella, Dunaliella, Oedogonium, and Volvox .Class Charophyceae The Chlorophyceae are one of the classes of green algae, distinguished mainly on the basis of ultrastructural morphology.For example the chlorophycean CW clade, and chlorophycean DO clade, are defined by the arrangement of their flagella.Members of the CW clade have flagella that are displaced in a "clockwise" (CW, 1–7 o'clock) direction e.g. Chlorophyceae is one of three most species-rich green algal classes and also the only class in core Chlorophyta whose monophyly remains uncontested as gene and taxon sampling improves. (1995) The Chlorophyceae are one of the classes of green algae, distinguished mainly on the basis of ultrastructural morphology. Examples are Chlamydomonas, Spirogyra, and Chara. The green algae are of three types, each of which presented below as two classes: Chlorophyceae and Ulvophyceae. Algae Classification.

Adl SM, Simpson AGB, Lane CE et al. Guiry, M.D. —, 1976: The generaSpongiococcum andNeospongiococcum (Chlorophyceae, Chlorococcales) III. Green algae – Chlorophyceae. Three main types of reproduction are found in Chlorophyceae, i.e., (1) Vegetative, (2) Asexual and (3) Sexual. Pigmentation 2. Description. Chlorophyceae are mainly fresh water algae (about 90 percent species are fresh water and 10 percent marine). The classification of this group is often hampered by the predominance of microscopic cells, fre - quently lacking obvious structures used to discriminate species or genera.
