Algae: Occurrence, types, classification, economic importance Topics covered: Introduction to algae. biotechnology 1st year But biologists wanted a broader system of classifying living organisms. Green algae are considered to be the ancestors of the higher land plants. These are -phyta for division, -phyceae for class, -phycideae for subclass, -ales for order, -inales for suborder, -aceae for family, -oidease for subfamily, a Greek-based name for genus, and a Latin-based name for species. Content Guidelines 2. Economic importance. A generally agreed classification of algae recognizes nine broad taxonomic groups, called Divisions. Linnaeus in 1753 was first to introduced the term algae (Latin- seaweeds) meaning, the Hepaticeae. no.- 161103004 m.sc. According to the Whittaker scheme, algae are classified in seven divisions, of which five are considered to be in the Protista kingdom and two in the Plantae kingdom. The absence of any motile cells in their life-cycle and presence of phycobiliproteins are unique features of the red algae. One flagellum is long and the other is short. Disclaimer Copyright, Share Your Knowledge Cyanobacteria variety belongs to Kingdom Monera, and the algae types kelps and phytoplanktons belong to Kingdom Protista. Thallus Structure of Lichens (With Diagram). TOS4. Based on their general features, algae are grouped into Kingdom Protista. We have moved all content for this concept to for better organization. They can be invasive, with some species fouling beaches. In this article we will discuss about the classification of rhodophyta. Important characteristics: They are commonly found in fresh water bodies. Types of Algae. Cryptophyta. They are commonly found in aquatic environments including freshwater, marine and brackish water. Closely related organisms (i.e., organisms having similar characteristics) are placed into the same taxon. 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. Classification of Algae 1. Share Your PDF File Hence came the five kingdom classification. There is three main Algae classification: Chlorophyceae – These are called green algae, due to the presence of pigments chlorophyll a and b. 'algae' is one of convenience and it includes simple photosynthetic organisms not included These are Chlorophycophyta, Xanthophycophyta, Bacillariophycophyta, Phaeophycophyta, Rhodophycophyta, Chrysophycophyta, Euglenophycophyta, Cryptophycophyta and Pyrrophycophyta. algae are either unicellular organisms or, if multicellular, then with one-celled Algae exist in environments ranging from oceans, rivers, and lakes to ponds, brackish waters, and even snow. They have the following characteristics: They are multicellular organisms with walled and frequently vacuolate eukaryotic cells. Click on names to … It is also called as Algae-Fungi because most of the characteristics of them are similar to algae like Vaucheria. 15:16. Algae are a diverse group of aquatic organisms that have the ability to conduct photosynthesis. Chlorophyceae (green algae) Phaeophyceae (brown algae) Rhodophyceae (red algae). According to the molecular classification, Green algae is associated with plants kingdom and have mitochondria with lamellar cristae. Land plants were then placed in separate divisions. Rests of two groups of Fungi are considered in the kingdom Plantae. . The majority of algae are plants, so they are in the kingdom plantae. The formal classification scheme in use today consists of a series of 7 major categories or taxa (singular, taxon). Chlorophyta belong to the kingdom Plantae. Algae are organisms, or living things, that are found all over the world. In general algae can be referred to as plant-like organisms that are usually photosynthetic and aguatic, but do not have true roots, stems, leaves, vascular tissue and have simple reproductive structures.

Welcome to BiologyDiscussion! 3. Only six genres of this group inhabit in freshwater. The Classification of Algae Table below lists some of the larger groups of algae. Some algae, such as seaweed, look like plants. Lichens pose a problem for biological classification, because the three types of organism concerned come from three different kingdoms.After long debate, lichen are now classified as fungi, under the genus and species of the host fungus. Algae belong to the kingdom Protista, and are simple photosynthetic organisms. Algae - Algae - Physical and ecological features of algae: The size range of the algae spans seven orders of magnitude. 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. A generally agreed classification of algae recognizes nine broad taxonomic groups, called Divisions. The eukaryotic algae (those with compartmentalized cells) are part of a diverse group of organisms called protists. Certain algae are familiar to most people; for instance, seaweeds (such as kelp or phytoplankton), pond scum or the algal blooms in lakes. Strictly, the For instance, algae living in snow contain carotenoid pigments in addition to chlorophyll, hence giving the surrounding snow a distinctive red hue.

There are different types of algal classification The term But despite the development from two kingdoms to five among most scientists, some authors as late as 1975 continued to employ a traditional two-kingdom system of animals and plants, dividing the plant kingdom into subkingdoms Prokaryota (bacteria and cyanobacteria), Mycota (fungi and supposed relatives), and Chlorota (algae and land plants). Algae have since been reclassified as protists, and the prokaryotic nature of the blue-green algae has caused them to be classified with bacteria in the prokaryotic kingdom Monera. Algae are the aquatic eukaryotic organisms that have chlorophyll and carry out oxygen-producing photosynthesis. Answer: R. H. Whittaker proposed the five kingdom classification. In addition, algae may occur in moist soil or on the surface of moist rocks and wood. Systems of Biological classification.

Among these, the members of the first five Divisions are distinctly plant-like organisms, but the others, particularly the flagellates, have some animal-like characters. They convert sunlight to starch that is stored as a food reserve. The five kingdom classification are- Monera, Protista, Fungi, Plantae and Animalia. Red algae are protists or microscopic organisms in the phylum Rhodophyta, and range from simple one-celled organisms to complex, multi-celled organisms. Return to INTRODUCTION: CLASSIFICATION SYSTEM. PLANT KINGDOM. In fact, green algae might have been the progenitors of the higher green plants, but that is the subject of debate. The green algae (singular: green alga) are a large, informal grouping of algae consisting of the Chlorophyta and Charophyta/Streptophyta, which are now placed in separate divisions, together with the more basal Mesostigmatophyceae, Chlorokybophyceae and Spirotaenia. They are either motile or non-motile. The cell walls are composed of cellulose and alginic acid (a complex polysaccharide). Order Ulotricales includes 80 genera and about 430 species. Earlier, Euglenoids were classified with plant kingdom (in algae) and animal kingdom (protozoa). Classification of Chlorophyceae (Green Algae) Classification of Chlorophyceae or Chlorophyta (Green Algae): The class Chlorophyceae divided into following orders: Order. The word algae represents a large group of different organisms from different phylogenetic groups, representing many taxonomic divisions. Based on the occurrence of pigments and food reserves, algae are classified into different types, namely blue green algae (BGA), green algae, red algae, and brown algae. The classification of algae depends on its features. Classification. In recent years, the simple division of the living world into sporangia (they never produce multicellular embryos inside the female reproductive organ). Algae are very important because they make much of Earth’s oxygen, which humans and other animals need to breathe. •The current systems of classification of algae are based on the following main criteria: o kinds of photosynthetic pigments, o type or chemical nature of photosynthetic energy storage products o photosynthetic membranes’ (thylakoids) organization and other features of the chloroplasts. Out of these classifications, five are considered in the Kingdom Protista. It is important to mention that this group of brown algae are considered as the main primary producers, forming the basis of a food chain; that is made up of several species of animals within their ecosystem. Most of them are found in fresh water, while a few are marine (e.g., Ulva).
