The kingdom Protista (once included partly in the animal kingdom and partly in the plant kingdom) is now divided into a number of as yet not adequately circumscribed kingdoms. Kingdom Protista (Protoctista) [250,000 species]: Unicellular protozoans and unicellular & multicellular (macroscopic) algae with 9 + 2 cilia and flagella (called undulipodia). Phaeophyta or brown algae are a group of autotrophic, multicellular organisms, belonging to the class Phaeophyceae in the division Chromophyta. Unicellular algae occur most frequently in water, especially in plankton.Phytoplankton is the population of free‐floating microorganisms composed primarily of unicellular algae. . A generally agreed classification of algae recognizes nine broad taxonomic groups, called Divisions. algae are either unicellular organisms or, if multicellular, then with one-celled The absence of any motile cells in their life-cycle and presence of phycobiliproteins are unique features of the red algae. 1st ed.

Welcome to BiologyDiscussion! Examples are... Phaeophyceae – Also called as brown algae, they are predominantly marine. Economic importance. Algae belongs to four different kingdoms, including the kingdom bacteria, kingdom plantae, kingdom protista and kingdom chromista. The presently accepted classification of the Rhodophyta having the single class Rhodophyceae is the system first devised by Schmitz (1883) and refined through years of painstaking work by Kylin (1932) and others to a form finally adopted and presented by Kylin in his monograph of 1956. For example, Euglena is included both in algae and in the protozoa under the class Phytomastigophora. Plantae - Plant Kingdom, Algae – Thallophytes: Green Algae, Brown Algae, Red Algae, Uses of algae, Bryophytes, Pteridophytes, Cryptogamae. Privacy Policy3. According to the records, there are more than 50,000’s known species of Algae and based on their habitat, presence of biological pigments and other characteristics they are classified into seven different types. Green algae are considered to be the ancestors of the higher land plants. These are Chlorophycophyta, Xanthophycophyta, Bacillariophycophyta, Phaeophycophyta, Rhodophycophyta, Chrysophycophyta, Euglenophycophyta, Cryptophycophyta and Pyrrophycophyta. However, algae are actually neither plants nor animals. Algae are usually green, but they can be found in a variety of different colours. Classification.

Algae are a diverse group of aquatic organisms that have the ability to conduct photosynthesis. Cyanobacteria variety belongs to Kingdom Monera, and the algae types kelps and phytoplanktons belong to Kingdom Protista. Phylum Cyanophyta ( Cyanobacteria ) Phylum Rhodophyta There are many types of algae; however, these are some of the more prominent types: Red Algae. They are commonly known as brown algae, due to the presence of a golden brown xanthophyll pigment, fucoxanthin (C 40 H 54 O 6) in the chromatophores. According to the classification system adopted by Day et al. The members of phaeophyta belonging to Laminarales are called kelps. The organisms which are placed under the kingdom Animalia are heterotrophic and depend on the other organisms for food. Algae are simple, thalloid, autotrophic, chlorophyll-bearing and aquatic (fresh water & marine) organisms. Return to INTRODUCTION: CLASSIFICATION SYSTEM. Description of Phaeophyceae (Brown Algae): It is a large group of algae consisting of 240 genera and over 1,500 species out of which 32 genera and 93 species are reported from India. Older classifications, as on the left, treated all green algae as a single division of the plant kingdom under the name Chlorophyta. The prokaryotic algae (the cyanobacteria) are included with bacteria in the kingdom Monera. Biologist Whittaker gave us the Five Kingdom Classification, classifying all the living organisms into five kingdoms – Protista, Monera, Fungi, Plantae, and Animalia. What are the general characters of bryophytes? The majority of algae are plants, so they are in the kingdom plantae. Introduction to algae.

These algae belong to the kingdom of Protists, with approximately 265 genres of about 2000 species, mostly seaweed. The Classification of Algae Table below lists some of the larger groups of algae. Originally, Chlorophyta referred to a division within the Plantae kingdom comprising all green algae species. Others are non-motile, and some (called seaweeds) are truly multicellular. They contain the xanthophyll pigment – fucoxanthin, in addition to chlorophyll a and c. Hence, the members of phaeophyta exhibit … kingdom) is now divided into a number of as yet not adequately circumscribed kingdoms. Alternative Titles: Phycophyta, alga, algas Algae, singular alga, members of a group of predominantly aquatic photosynthetic organisms of the kingdom Protista. What is the world's most endangered animal? These characteristics include the photosynthetic pigments, nature of photosynthetic reserve materials, the composition of cell wall or absence of cell wall, cellular and thallus morphology and reproductive behaviour.
