The algae are autotrophic protists that can be unicellular or multicellular. Extended Reading: Chloroplasts. Books. Books. Their photosynthetic pigments are more varied than those of plants, and their cells have features not found among plants … Compare the mode of nutrition of a heterotroph to that of an autotroph and give examples of each. In five-kingdom classification, unicellular green algae are included in the kingdom . The green algae, recently placed in the plant kingdom, have both multicellular and unicellular forms. Protists are a large group of diverse eukaryotic microorganisms, mainly unicellular animals and plants, that do not form tissues. Since the green algae are very closely related to plants on a molecular level, but distantly related to some other protists, the clade Viridiplantae (meaning "green plants") includes the green algae and all other organisms with chlorophyll a/b (not found in all algae). Protista is, i find, one of those taxonomical groups that contain all the life forms that don't fit anywhere else. These organisms are found in the supergroups Chromalveolata (dinoflagellates, diatoms, golden algae, and brown algae) and Archaeplastida (red algae and green algae). Three groups of seaweeds are recognized. In the five-kingdom system, slime molds and multicellular algae are included in the kindgdom protista because? Like other algae, green algae serve as an important food source for herbivorous marine life, such as fish, crustaceans, and gastropods, including sea snails.Humans use green algae as food, too. In summarizing the difference between algae and protozoa, algae are plant-like organisms that are capable of photosynthesizing while protozoa are unicellular animal-like organisms that are heterotrophs. In five-kingdom classification, unicellular green algae are included in the kingdom . They are important ecologically and environmentally because they are responsible for the production of approximately 70% of the oxygen and organic … -unicellular green algae (Division Chlorophyta) in the Kingdom Protista-Cyanobacteria: Prokaryotic organisms that can perform the same kind* of photosynthesis that plants do. Not an Algae: Blue-green Algae. Members are unicellular, multicellular, colonial and flagellates. • Chlorella - Non motile unicellular alga.

Nov 29,2020 - The slime moulds and unicellular algae are presently included in the kingdom-Protista becausea)They appear to be more closely related to unicellular eukaryotesb)They lack important characteristics of the fungi and plantsc)Kingdom-Protista includes eukaryotic organisms that do not clearly belong in the other three kingdomsd)All of the aboveCorrect answer is option 'D'. Is red algae unicellular or multicellular? A representative member is Chlamydomonas, which is often used in research and as a laboratory specimen.Chlamydomonas produces zoospores, which are flagellated.Organisms such as Chlamydomonas are believed to be evolutionary ancestors of other species. Monera are prokaryotic unicellular bacteria whose genetic material is dispersed loosely in the cell. Included organisms range from unicellular microalgae, such as Chlorella and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to 50 m in length. Prominent examples of green algae include Spirogyra, Ulothrix, Volvox, etc. Therefore, blue green algae are placed in Kingdom Monera and not inKingdom Plantae. Actually Seaweeds belong to three kingdoms: Kingdom Plantae (chlorophyte, or "green" algae … Slime mounds and Protozoa are in Protista. Green algae are often classified with their embryophyte descendants in the green plant clade Viridiplantae (or Chlorobionta). Therefore, blue green algae are placed in Kingdom Monera and not inKingdom Plantae. The kingdom contains all photosynthetic eukaryotic multicellular plants and their non-photosynthetic relatives. ... Blue green algae belongs to the kingdom Protista. a) They appear to be more closely related to unicellular eukaryotes b) they lack important characteristics of the fungi and plants. Algae are included in . Green algae may be unicellular (one cell), multicellular (many cells), colonial (living as a loose aggregation of cells) or coenocytic (composed of one large cell without cross-walls; the cell may be uninucleate or multinucleate). Other groups included in the kingdom plantae are bryophytes, pteridophytes and spermatophytes. The green algae include unicellular and colonial flagellates, usually but not always with two flagella per cell, as well as various colonial, coccoid, and filamentous forms. Cyanobacteria resemble the eukaryotic algae in many ways, including morphological characteristics and ecological niches, and were at one time treated as algae, hence the common name of ... Out of these classifications, five are considered in the Kingdom Protista. to kingdom (a) Protista (b) Monera (c) Fungi (d) Plantae Ans : (b) Monera Organisms without nucleus and cell organelles belong to Kingdom Monera. Extended Reading: Chloroplasts. No , sea weeds (Algae ) are included in kingdom Protista , they don't have their own kingdom . Oh no! Division Chlorophyta. The ancestral green alga was a unicellular flagellate. Entering the world of algae is fascinating when you want to know the evolutionary history of plants, and that is because the Kingdom Plantae as we know it today, has its origin in the sea. Yellow-green algae (Xanthophyta) These unicellular organisms are the rarest and least prolific species of algae with only 450 to 650 species. 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. Which of the following statements is false? Jan 20, 2020 - We are a bunch of people with desired skills & qualifications who are passionate about Biology teaching. 36. 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. It is considered a Paraphyletic Group. The group of organisms collectively referred to as "Algae" were at one time included entirely in the kingdom of Plantae. Prominent examples of green algae include Spirogyra, Ulothrix, Volvox, etc. The green scum you see in an aquarium is called _____.
