In the present chapter an attempt has been made to collectively put forward different classification systems as … The primary classification of algae is based on certain morphological features. classification of algae was given by F.E Fritsch (1935) in his book ‘The Structure and Reproduction of the Algae’. Phaeophyceae is divided into 9 orders by Fritsch. Taxonomically Green Seaweed can be classified into two divisions:. Chlorophyte. There are different types of algal classification based on their characteristic. Algae are also known as 'Sea-Weeds', 'Pond-Scum' and 'Grasses of Water'. Algae are placed in kingdoms monera, protista and plantae. Common Classification 1. Since Linnaeus (1753) published “Species Plantarum” and classified algae. 500 worda on algae. This article explores, 1. Ø Different groups of algae have different pigment composition. 45. The members of phaeophyta belonging to Laminarales are called kelps. Also referred to as blue-green algae and blue-green bacteria, cyanobacteria is a bacteria phylum that obtain their energy through a process known as photosynthesis. They also possessed beta-carotene that is yellow colour photosynthetic pigment. 3. The other two major classes are Chlorophyceae (green algae) and Rhodophyceae (red algae). 1.2 ChARACtERIStICS Filamentous algae and seaweeds have an extremely wide panorama of environmental requirements, which vary according to species and location. These Algae consists of photosynthetic pigments eg. Brown Algae Classification and Examples . Scientific Classification Domain - Eukaryota. kyanas, a dark blue substance; phyton, a plant) while other workers believed that … The first group is the diatoms, which have a cell wall composed of silica. Algae term is used for all photosynthetic microbes. while fungi are eukaryotic heterotrophs that grow hyphae threads to form a … The term algae mean Aquatic Plants but differ from the plants in lacking a well-organized vascular conducting system and in having very simple reproductive structures. The main difference between algae and bryophytes is the division of the plant body; no division of labour is observed in the plant body of algae whereas the plant body of bryophytes internally divides into photosynthetic and storage zones. Deglint J.L., Jin C., Wong A. Plant body is commonly unbranched fila­ment like ; but in Ulvaceae it is parenchymatous or foliaceous. They can complete 50% to 60% of all photosynthesis on the planet. Preview; Assign Practice; Preview. Xanthophyceae or yellow—green algae e.g. What are Algae – Definition, Classification, Characteristics 2. 2. o the presence or absence of flagella (as well as the number and Both algae and fungi form thallus. its classification and characteristics - 4634552 Algae, singular alga, members of a group of predominantly aquatic photosynthetic organisms of the kingdom Protista.Algae have many types of life cycles, and they range in size from microscopic Micromonas species to giant kelps that reach 60 metres (200 feet) in length. Algae live with fungi in lichens.. Dr. Poonam Jaiswal, Lecturer Botany, JDB Govt. Because they require the basic environmental conditions, this bacteria can be found in a variety of environments ranging from marine to terrestrial habitats. They are commonly found in aquatic environments including freshwater, marine and brackish water. ... Algae Classification: The Euglenoids. The account of algae dates back to ancient Chinese literature and it is a believe that along with the origin of plant sciences, the recognition of algae as a group has taken place. Algae produce an estimated 30 to 50 percent of the net global oxygen available to humans and other terrestrial Animals for respiration. Fritsch’s Classification: The algae have broadly been divided by F. F. Fritsch in 1935 into eleven classes according to their colour: i. Chlorophyceae or green algae, e.g. Learn more: Lecture Note in Algae General Characteristics.

The main orders are: Ectocarpales – e.g. Ø Distribution pattern of pigments has great taxonomic significance in algae. Chlorophyta are eukaryotic organisms, mostly aquatic photosynthetic type. The Five Kingdom System of Classification Although algae are so diverse in nature and form, there are still a few characteristics on the basis of which they can be classified. girls college, Kota In addition, algae may occur in moist soil or on the surface of moist rocks and wood. MEMORY METER. These plants live in aquatic environments , mainly in the sea; but some species can be found in freshwater. Ø The classification of algae by Fritsch is primarily based of the pigmentation in algae. The main difference between algae and fungi is that algae are autotrophs, containing chlorophylls for photosynthesis whereas fungi are heterotrophs, obtaining organic material from the sources in the external environment. It should be noted that the classification of living organisms is a complex and controversial subject.
