characteristics of algae and fungi

Algae exist in a variety of shapes and forms—single-celled algae may be spherical, rod-shaped, or spindle-shaped, while multicellular algae may appear as colonies, filaments or tubes. Most of them inhabit in freshwater environment. The study of algae is known as Phycology. Algae cell wall composed of cellulose and pectin. They have unicellular, filamentous, colonial, or multicellular and plantlike bodies. Although algae are so diverse in nature and form, there are still a few characteristics on the basis of which they can be classified. Alternation of generations occurs in their life cycle. The primary photosynthetic pigments are chlorophyll a and chlorophyll b. Meiosis cell division is seen in different stages of life cycle. Cell wall consists of cellulose, hemicellulose, and calcium carbonate in some species. They store food as starch inside the chloroplast. If present, flagellum possesses hair like projection. They have unicellular, colonial, filamentous, or multicellular body. They have both unicellular and colonial forms. amzn_assoc_title = "Shop Your Products"; Asexual reproduction in algae occurs through vegetative reproduction meaning that if any part of the algal fragment breaks, it is capable of turning into a new algal colony or individual. Keshav Narayan Pai Msc I Department of Botany 2. amzn_assoc_search_bar = "true"; The multi-cellular algae develop specialized tissues but they lack the true stems, leaves, or roots. Characteristics of Fungi. And whales and shrimps love to feast on algae as it is loaded with protein. Lichens are a complex life form that is a symbiotic partnership of two separate organisms, a fungus and an alga. Algal cells are primarily eukaryotic cells with membrane-bound photosynthetic (chloroplast), respiratory (mitochondria) and genetic organelles. This group contains algae that are commonly utilized by humans, animals, and fish as food. They contain pigments like chlorophyll 'a', 'b', and phycobilins and they appear in blue green color. The fungal component of lichen is called mycobiont and the algal component of lichen is called phycobiont. The chlorophyll in these algae is hidden by brown pigments, which gives them their typical golden color. They are used as a stabilizer in milk products. They are unicellular or multicellular Eukaryotic organisms. One such important group of organisms is algae. Cell wall. Cryptomonas, Chilomonas,  Falcomonas,  Rhinomonas, Plagioselmis,  Teleaulax, etc. With a few exceptions, most algae are autotrophic; they do not have vascular tissues.

Algae is a plant-like organism (but not plant) that often grows inside or near fresh-water bodies. Sexual reproduction is unknown among the representatives of Pleurastrophyceae. Some aquatic algae produce harmful toxins that cause the death of fishes, shellfishes etc. This phylum contains more than 1,500 described species. They contain pigments like chlorophyll a, chlorophyll b, carotenoids, and xanthophylls. They contain single lobed chloroplast with central pyrenoids. - cool water, often near the surface. You can find them in the seas, salt lakes, freshwater lakes, oceans, damp soil, on rocks, stones, tree bark, and even other plants and animals. They also form a symbiotic relationship with plants or lichen-forming fungi. 3. Gametangia (reproductive organ) always single celled, if multi-celled, do not cover with sterile cell layer. In this case, kelps reach up to 60 meters (200 feet) in length. amzn_assoc_marketplace = "amazon"; Gonyostomum, Vacuolaria, Merotricha,  Chattonella, Chlorinimonas,  Haramonas, Psammamonas,Fibrocapsa, Heterosigma, and Viridilobus, etc. Mitochondria contain paddle-shaped cristae. The cell body is asymmetric with dorsi-ventral sides. They perform sexual reproduction which is isogamous type. Algae and fungi are two groups of organisms, which belong to kingdom Protista and kingdom Fungi respectively. Examples: Let’s talk about some of the good they do. We co-exist with a whole bunch of different and varied living organisms, including other animals, plants, bacteria, viruses, algae and fungi. Deposits of these silica shells are called diatomite or diatomaceous earth, and this material is often used for insulation and as a filter for filtering cane sugar, wines, beverages etc. Fungi Some fungi contain multinucleated cells. Explore kingdom fungi, characteristics and classification of fungi, its structure, and examples at BYJU'S. They carry out probably 50% to 60% of all the photosynthesis on the earth.

Dinophysis, Alexandrium,  Gonyaulax, Ceratium,  Noctiluca, Gymnodinium,  Polykrikos, Peridinium,  etc. This group contains about 6,000 described species. eval(ez_write_tag([[336,280],'scienceabc_com-large-mobile-banner-1','ezslot_6',181,'0','0']));Xanthophycophytahave a typical pale green or yellow-green color as a result of their unique pigments and are often found in temperate regions. The cell contains numerous ellipsoid chloroplasts. mycorrhiza: a symbiotic association between a fungus and the roots of a vascular plant; spore: a reproductive particle, usually a single cell, released by a fungus, alga, or plant that may germinate into another; lichen: any of many symbiotic organisms, being associations of fungi and algae; often found as white or yellow patches on old walls, etc. Examples: Fisiology and ecology of algae. amzn_assoc_tracking_id = "mywebsit03240-20"; Examples: Ecologically, they can be grouped into the following types by their habitats. Fungi is a eukaryotic organism that can be unicellular or multicellular. Many algae live as endophytes in plant or animal tissue and many grow on plant or animal as epiphytes. The cell wall also prevents over-expansion when water enters the cell. Habit and Habitat They may be free floating , free swimming or attached to the bottom in the shallow water. amzn_assoc_ad_mode = "search"; They store food materials as starch and oil. The cell wall is composed of pectic compounds. This phylum contains over 7000 recognized species. Photosynthetic pigments are chlorophyll a, chlorophyll e,  xanthophyll or carotenoids. More than 30000 species of algae have been identified. However, they are not structurally similar to plants in their external appearance, which means that their bodies are not differentiated into roots, stems, leaves etc.eval(ez_write_tag([[300,250],'scienceabc_com-medrectangle-3','ezslot_0',169,'0','0'])); It’s very difficult to give a precise definition of algae because of their varied nature. This cell wall in some algae is further surrounded by a flexible outer matrix, very similar to a bacterial capsule. Some algae might be one-celled (unicellular) organisms comparable to the size of bacteria, while others may grow to many feet in length like seaweed. They are also known as Cynabacteria. Lichens are structurally organized permanent symbiotic association between fungi and algae. These three products are agar, carrageenan, and alginate. Due to the presence of different photosynthetic pigments, algae are found in different colors like green, red, brown, but mostly green in color. In this case, photosynthetic pigments are chlorophylls a and chlorophyll b. Algae are unicellular, colonial or large multi-cellular organisms. Chrysamoeba,  Lagynion, Chrysocapsa, Ochromonas, etc, Examples: The flagellum does not contain tubular hairs. Algae tend to disintegrate concrete, which makes the water corrosive. Algae are chlorophyll-bearing autotrophic thalloid plant body. They store foods as pyrenoids outside of chloroplasts. The photosynthetic pigments are chlorophyll a, chlorophyll c and fucoxanthin. Examples: Examples: They are both photosynthetic and heterotrophic organisms. The cell possesses two anteriorly directed flagella with tubular hairs on one or both flagella. This class contains more than 50 described species. Fungi in the morphological vegetative stage consist of a tangle of slender, thread-like hyphae, whereas the reproductive stage is usually more obvious. Based on colors, algae are divided into the following major four groups: ​They belong to the class Cyanophyceae under the phylum Cyanophyta. Algae: Algae contain unadulterated cells. They possess many types of life cycles and their size range from microscopic Micromonas species to giant kelps. Heterotrophs ... Lichens - Symbiotic relationships between lichens and algae. Systematic and Taxonomy. This class contains about 200 described species. amzn_assoc_tracking_id = "mywebsit03240-20"; Hot Water Vs Cold Water: Which Extinguishes Fire Faster? The cells have typically two slightly unequal flagella. They lack a true cell wall, and the body is bounded by a proteinaceous cell covering which is known as a pellicle. Ascophyllum, Ectocarpus, Laminaria,  Fucus, Nereocystis, Macrocystis,  Pelagophycus,  Postelsia, Pelvetia,  Sargassum, etc. They inhabit in freshwater or in a wide variety of moist soils of a terrestrial environment. The cell contains a silica cell wall which is known as frustules. The male gametes possess heterokont flagella. Dr. Maneka Vig is an experienced dental surgeon with 8 years of dental practice behind her. They inhabit in both in freshwater or marine environments. They are commonly found in freshwater environment. Micromonas, Ostreococcus, Pyramimonas, etc. Cells contain photosynthetic chlorophyll and other pigments. Eustigmatos, Botryochloropsis,Pseudocharaciopsis, Ellipsoidion , Pseudellipsoidion, Nannochloropsis,Pseudostaurastrum,   etc. They contain pigments like chlorophyll a and chlorophyll b. The majority of the members contain one chloroplast per cell. Often, they are commonly known as sea water planktons. Algae live with fungi in lichens. Some commonly known algae like Chlamydomonas, Volvox, and Spirogyra are members of Chlorophycophyta. eval(ez_write_tag([[580,400],'scienceabc_com-box-4','ezslot_2',170,'0','0']));The cell wall of algae gives us three very important products that are used widely on a commercial scale. amzn_assoc_default_browse_node = "13900871"; amzn_assoc_placement = "adunit0"; These types of algae belong to the class Phaeophyceae under the phylum Phaeophyta. Examples: Almost all the algae are aquatic. Examples: A nucleus is present, and multiple chromosomes are observed in mitosis. Phaeophycophyta (brown algae) – This variety contains a characteristic brown pigment and is therefore called brown algae. amzn_assoc_default_category = "Shoes"; Most algae store carbohydrate as reserve food, few members contains alcohol, fat or oil as reserve food. The plant body may be unicellular to large robust multicellular structure. In this case, sexual reproduction is isogamous type. They perform alternation of generation with haplobiontic or diplobiontic life cycles. Fungi are Eukaryotic organism. Sexual reproduction is anisogamous, isogamous, or oogamous types. Examples:  Dictyota, Laminaria, Sargassum, etc. They possess a counter-clockwise orientation of the basal bodies and an unusual mitotic spindle. Several species of algae attack the leaves of tea, coffee, pepper etc. ADVERTISEMENTS: 3. They as such live as saprophytes or parasites. They inhabit in soil, freshwater and marine environments. Algae grow abundantly in water reservoirs that are meant for the water supply, but they tend to produce undesirable odors and tastes, especially algae belonging to the genus Synura. Reproductions occur through binary fission, sporogenesis, etc. They are a small group of unicellular heterokont algae. The multicellular complex thalli lack vascu­lar tissue and also show little differentiation of tissues. Cryptophycophyta– These have slipper-shaped or flattened oval cells with two unequal flagella (biflagellate).eval(ez_write_tag([[728,90],'scienceabc_com-leader-2','ezslot_10',175,'0','0'])); Members of Pyrrophycophyta tend to demonstrate a twirling motion owing to the “whirling” of their two dissimilar flagella; thus, they are called dinoflagellates. Are Giant Insects Larger Than Humans Possible? They also happen to be of great importance to us humans, owing to the huge range of algal products we use, but they can also be toxic, so it’s imperative to educate ourselves better about this huge and impressively diverse kingdom or organisms! They contain pigments like chlorophyll a, chlorophyll b and beta-carotene. Origin and taxonomy. Wave-Particle Duality: Is An Electron A Particle Or A Wave? There are five types of chlorophylls (a,b,c,d,e), two types of carotenoids (carotenes and xanthophylls), and two types of phycobilins (phycocyanin and phycoerythrin). So, Keep reading…! amzn_assoc_default_search_phrase = "Tablets"; They are also known as brown algae or brown seaweeds. They possess two or more apical flagella, if present. Green algae, brown algae, red algae, golden-yellow algae are main types of algae. Order-2: Chlamydomonadales (e.g. They are mostly marine with unicellular or multicllular body. Chrysophycophyta (golden algae) – These algae have flagella and are mostly unicellular, but some also tend to form colonies. The Eukaryotes: Fungi, Algae, Protozoa, and Helminths. 1. They also grow on the body surfaces of other organisms such as turtles and polar bears, on rocks or in the soils, or under or inside porous rocks, such as limestone and sandstone. ​They may be either unicellular or multicellular algae which belong to the class Chlorophyceae  under the phylum Chlorophyta. amzn_assoc_placement = "adunit0"; Carrageenan is used as a thickening compound in shaving creams and lotions, while alginate is commonly used by dentists to make impressions of your teeth when you need a new crown or braces. The body possesses large and prominent nucleus and a contractile vacuole for performing osmo-regulation. Examples: They inhabit in both freshwater and marine habitats. They contain chlorophyll a and chlorophyll c. They also contain accessory pigments such as Carentoids, xanthophylls. There are about 180 known species under 13 genera. 6 Interesting fun facts about algae and fungus During photosynthesis, they produce oxygen with help of light energy from the sun and generate carbohydrates. amzn_assoc_linkid = "df6e3e2dfb2223ece0caaeddeb1e4806"; The motile form possesses two different flagella. amzn_assoc_search_bar_position = "bottom"; The thylakoids are stacked in triplets and it contains chlorophyll a and chlorophyll c. They are photosynthetic organisms which contain pigments like chlorophylls a and c. The cells also contain accessory pigments such as β-carotene and diadinoxanthin. Characteristics of Algae. In this case, frustule is made up of two valves called thecae. Algae are found in different colors like green, red and brown due to the … Fungi are heterotrophs and are capable of digesting external, non-living, organic material and absorbing simple nutrients by the fungal hypae.

They are mostly motile and photosynthetic algae containing pigments like chlorophyll a, and chlorophyll b. They are heterotrophic or autotrophic (photosynthetic) organisms. The major polysaccharides making up the primary cell wall of land plants are cellulose, hemicellulose, and pectin. Characteristics of Fungi Fungi are eukaryotic organisms means they have true nucleus which are enclosed in membranes. They show the presence of contractile vacuoles and fibrils, which are animal characteristics, and they also carry out photosynthesis, which is a plant trait. Have been identified pattern of microtubules contain two or more flagella which lack tubular hairs ( )! Photosynthetic marine organisms but few are parasitic behind her high economic value, particularly Gelidium, from agar. And an alga has eukaryotic properties, and multiple chromosomes are observed in mitosis or laterally placed flagella lack. With 10–50 μm in length may be either a green alga or a Wave Porphyra Rhodymenia. €œWater felt” or Voucheria is a filamentous alga usually found in brackish- and freshwater habitats very difference.
