Shilapushpa or Lichens are simplest form of plants consisting of a very intimate association of a fungus (the mycobiont) with a photosynthetic partner (the photobiont), usually either a green algae or cyanobacterium.The intimate association of these two microorganisms results in the formation of a macro-organism, i.e. Green algae usually have a rigid cell wall made up of an inner layer of cellulose and outer layer of pectose. Reproduction in fungi is both by sexual and asexual means. West Bishop; Algae and Aquatic Research Scientist .

Almost all the algae are aquatic. Protozoa are eukaryotic microorganisms. SHILAPUSHPA - LICHENS: GENERAL CHARACTERISTICS. Spores are formed in clusters around the base of the carpogonium (female sex organ) after fertilization. Introduction to Cyanophyceae: It is a primitive group of algae, consists of 150 genera and about 2,500 species. Conditions for survival include light, carbon, essential nutrients, water quality, temperature and tidal exposure. Occurrence 4. Although they are often studied in zoology courses, they are considered part of the microbial world because they are unicellular and microscopic. GENERAL DESCRIPTION OF MAJOR DIVISIONS AND CLASSES PROKARYOTES CYANOPHYTA (BLUE-GREEN ALGAE) AND PROCHLOROPHYTA -All blue-green algae (Figure 2.1) and prochlorophytes (Figure 2.2) are non-motile Gram negative eubacteria. They are distributed worldwide in the sea, in freshwater and in wastewater. They are usually green due to the presence of chlorophyll a, chlorophyll b and beta-carotene. The substance can either be used as an additive or can act as a thickener in many types of food products. Bioenergy, in general, is an imperative option to mitigate greenhouse gas emissions and to substitute fossil fuels . Ecologically, algae are the most widespread of the photosynthetic plants, constituting the bulk of carbon assimilation through microscopic cells in marine and freshwater. For example, in conifers, the dominant phylum of gymnosperms, there are female cones that grow in the upper branches of the tree and male cones grown on the lower branches. General Characteristics of phylum Protozoa. The thallus (tissue) consists of fine branched filaments each with a central axial filament supporting pericentral cells. Authors; Authors and affiliations; Dinabandhu Sahoo; Pooja Baweja; Chapter. A protozoan body consists of only mass of protoplasm, so they are called acellular or non-cellular animals. The bacteria that forms the natural flora of the intestines are very important for proper digestion. The Monera kill organisms causing pathogenic diseases, breaks down algae, and can even recycle chemical pollutants like hydrogen sulfide and ammonia. Algae can also be found in household products, such as toothpaste and various pharmaceuticals.

The environmental requirements of algae are not … Yeasts are unicellular fungi that do not produce hyphae. GENERAL CHARACTERISTICS OF FUNGI. 3. -Unicellular, colonies, filaments -They lack a nucleus and organelles (chloroplast, mitochondria).-Circular DNA, no chromosomes, no histone protein Third-generation biofuels use algae and, by several different means, produce FAME, biofuels, in addition to several ... primarily because of their compatibility with current engine technologies. Algae have simple, unicellular non-jacketed sex organs and have no embryo development. Algal proteins: extraction, application, and challenges concerning. Fungi is plural and fungus is singular. Bacteria are typically single-celled organisms called prokaryotes that may serve as digestive aids, cause disease or aid in decomposition. On the prokaryotic side, there are diverse forms of bacteria and a group generally termed blue-green algae. Habit and Habitat .

General characteristics. 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. The reproductive system of gymnosperm plants is located in the cones. For instance, algae can photosynthesize like plants, and they possess specialized structures and cell-organelles, like centrioles and flagella, found only in animals. 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. 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. Description. You're probably wondering how the algae benefits the fungus and vise versa. Science Photo Library - CDC/Brand X Pictures/Getty Images. ADVERTISEMENTS: 3.

Habitat: mostly aquatic, either free living or parasitic or commensal; Grade of organization: protoplasmic grade of organization. They are known as acellular or non-cellular organism. Plant body may be unicellular, colonial, filamentous or multicellular. Certain intertidal species such as the ulva, or sea lettuce, can tolerate a range of temperatures and survive drying at low tide.
