is Diatoms and brown algae are examples of algae with secondary chloroplasts derived from an endosymbiotic red alga. Sheets of agar gel are used in genetic research. grazing is severe. This post describes the similarities and major difference between algae and bryophytes. particularly well adapted to low light levels, and the Antarctic species During photosynthesis, algae produce at least half of the oxygen in Earth’s atmosphere. The other 98% are in the ocean. Phaeophyta Characteristics Phaeophyta are the most complex forms of algae. The food reserves contain sugar, higher alcohol and other complex forms of polysaccharides. They are unicellular photosynthetic flagellated algae. Most of the species are filamentous (single row of cells forming hairs). Algae. They are often termed as chlorophytes. These organisms are not necessarily closely related. Bryophytes are the most primitive land plants. Algae contain a discrete nucleus, along with starch grains, oil droplets and vacuoles. Photoautotrophic algae produce oxygen. of red algae outweighs the total biomass of brown algae (phaeophyceae: In Monterey Bay, California, Give an example form each group green, yellow, brown, red, blue-green, classified for their color, method of reproduction, and form in which their food reserves are stored; volvox, diatom, giant kelp, sea grapes, cyanobacteria (2).      Plant body is not differentiated into root, stem and leaves in both groups Similarities between Algae and Bryophytes. algae have, Rhodophyta also have 3 important chemicals in their cell walls. Green algae. Primarily, algae are not highly differentiated i… The main characteristic of this group is their immobility during all stages of their life cycle. Algae are photosynthetic microorganisms that perform photosynthesis and produce oxygen (O2) and consume carbon dioxide (CO2) from the atmosphere. Only two percent which is famous for the enormous brown algae, the total biomass (dry weight) 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. thick, fleshy thalli (bodies). it is an ancient division that branched off very early in the tree of life. • 8. Unlike green algae or Chlorophyta, they lack true starch. Most of the evolutionary biologists believe that bryophytes were originated from Algae. 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. They can also occupy on rocks, soils, vegetation, or moist […] Sexual reproduction may be isogamous, anisogamous or oogamous, Sex organs not covered with sterile jacket cells for production, Sex organs are always covered with sterile jacket cells for protection, Gametophytic and sporophytic generations are usually independent, Gametophytic and sporophytic generations are dependent and physically connected, Alternation of generation usually isomorphic, rarely heteromorphic, Alternation of generation always heteromorphic. red algae. Most of the evolutionary biologists believe that bryophytes were originated from Algae. What are the major groups of algae and what is the basis for their classification? 5.31: Cellular Characteristics of Algae: Algae—being eukaryotic organisms—have a cellular organization like that of other photosynthetic eukaryotes. In the warmer tropics grazing by fish and invertebrates (snails, etc.) Most of euglenoids are autotrophic and photosynthetic. Algae is the name given to a large and diverse group of oxygenic, phototrophic, eukaryotic microorganisms. Firstly, there are very few single celled Answer of Draw the Table of Divisions of Algae and their Main Characteristics. These chemicals are amorphous (shapeless) mucilages (mucuses) which are This belief is strongly supported by the similarities of many characters in algae and bryophytes. There are very few single celled red algae. Brown algae, from the phylum Phaeophyta (meaning "dusky plants"), is … The three main types of algae are green algae, red algae, and brown algae, while the three main divisions of division Embryophyta are mosses, hornworts, and liverworts. Fire algae (Pyrrophyta) Fire algae are unicellular organisms found in salt water environments with … The word algae represents a large group of different organisms from different phylogenetic groups, representing many taxonomic divisions. Algae reproduce asexually by cell division and fragmentation. Algae often protect themselves from grazers (like snails) by producing Answer of Draw the Table of Divisions of Algae and their Main Characteristics. Login; Register; Home (current) Notes & Question Bank.   Flagella of antherozoids are whiplash type in both groups, (15). This helps ensure that an entire algal population is not eaten up - at Similarities between Algae … (3).      Gametophytic generation is the prominent phase in life cycle in both groups Algae are eukaryotic, which means they have a nucleus. • 5. The Euglenophyta or euglenoids are unicellular species, protozoan-like algae, and dominant in the freshwater environment. Even though bryophytes are well adapted for the land life they require the presence of water for the completion of their life cycle. very fast flowing streams. • 6.   Both group can undergo vegetative reproduction by death and decay, fragmentation, and adventitious tubers, (13). Enter your e-mail address. Division-level classification, as with kingdom-level classification, is tenuous for algae. The terms “Algae ” was coined by C. Linnaeus which means ‘sea weeds’. Division Chlorophyta. The term \"algae\" covers many different organisms capable of producing oxygen through photosynthesis (the process of harvesting light energy from the sun to generate carbohydrates). This is because they don’t have flagella. Specific general characteristics of algae are common to plants as well as animals. Ø Algae are autotrophs (synthesize food using light energy) Ø Thalloid plant body Ø In Eichler’s system of classification, algae are placed in the Division Thallophyta along with Fungi and Lichens. 78 ºS of the equator. to survive Antarctica's long months of near darkness. ... • 4. Algae exhibit a wide range of reproductive strategies, from simple asexual cell division to complex forms of sexual reproduction. Listed below are some of the general characteristics of algae. Their plastids contain two membranes, chlorophyll, al well as accessories pigments of carotenoids and phycobiliproteins. They inhabit in both freshwater …   Filamentous protonema in the juvenile stage of bryophytes resembles the algal plant body, (17). However, all such atypical organisms are photosynthetic which justifies their inclusion in algae. kelps etc.) between 10-15 ºC. The Rhodophyta are distributed worldwide (see, for example, the distribution of Plocamium,) but they grow best in waters The cell walls are composed of cellulose and alginic acid (a complex polysaccharide). Algae, singular alga, members of a group of predominantly aquatic photosynthetic organisms of the kingdom Protista. Many algae reproduce sexually. Conclusion Algae are a type of lower plants that belong to the kingdom Protista. (4).      True roots are absent in both groups of algae and bryophytes, (5).      Both groups are autotrophic in nutrition, (6).      In both algae and bryophytes major photosynthetic pigments are chlorophyll a, b and carotenes, (7).      Vascular tissue is absent in both groups, (8).      Cellulose is chief consistent of cell wall in both groups, (9).      In both groups starch is the reserve food material, (10). Table 1 is a summary of algal divisions, restricted to those which possess a cell wall, and their most significant characteristics. And secondly, the gametes (. Schizophyta is an old group/division that consists of two classes namely, Schizomycetes (Bacteria) and Myxophyceae (blue-green algae/cyanobacteria). Cryptophyta. Both algae and bryophytes lack a vascular system. Under the new taxonomic classification, however, Schizophyta is referred to as cyanophyta and consists of blue-green algae (Myxophyceae). however, are over 10,000 species that have been described. Many algae are Photoautotrophic in nature and make their own food by the process of Photosynthesis. For example, some phycologists place the classes Bacillariophyceae, Phaeophyceae, and Xanthophyceae in the division Chromophyta, whereas others place each class in separate divisions: Bacillariophyta, Phaeophyta, and Xanthophyta. However, certain features unite them, while distinguishing them from the other major group of photosynthetic organisms: the land plants. different carrageenans that are indigestible to the herbivore. (1).      In both groups the plant body is thalloid and undifferentiated. The thallus of multicellular algae usually consists of a stipe, a holdfast, and blades. In these subclasses,   In Chlorophyceae (algae) and Anthocerotales (bryophytes) the plastids contains pyrenoids, (12). Asexual reproduction is common by a variety of spores such as zoospores, aplanospores, hypnospores etc. The Taxonomy of the Rhodophyta shows that Many filamentous forms, however, have evolved in such a way as to create much more extreme, and algae are often restricted to cracks and crevices. Based on their general features, algae are grouped into Kingdom Protista. Euglenophyta. their divisions include Cyanophyta, Prochlorophyta, Phaeo- phyta, Chlorophyta, Charophyta, Euglenophyta, Chry- sophyta, Pyrrhophyta, Cryptophyta and Rhodophyta. Characteristics Of Algae • 3. Examples are Chlamydomonas, Spirogyra, and Chara; Phaeophyceae – Also called as brown algae, they are predominantly marine. are adept at energy storage. Besides having the usual cellulose cell walls that most Certain species in the Rhodophyta are particularly well adapted to living widely used in science and food preparation. 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. Photosynthetic pigments: They possesses chlorophyll a, chlorophyll b and small amount of β-carotenoids. General Characteristics of Algae Algae are eukaryotic organisms that have no roots, stems, or leaves but do have chlorophyll and other pigments for carrying out photosynthesis. Background and Divisional Characteristics of Red Algae (Rhodophyta) The Taxonomy of the Rhodophyta shows that it is an ancient division that branched off very early in the tree of life. Different stages in an alga's life history can produce different forms of carrageenans. Euglena are fresh and salt water protists. (1).      In both groups the plant body is thalloid and undifferentiated. 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. They are immediate between aquatic and terrestrial life. Their plant body is a thallus. The Rhodophyta are But chlorophyte is actually a division of green algae, which includes both freshwater and marine species.
