General Characteristics and structures - members of this group include members that have flagellum with numerous fine, hair like projections. A.G.B. This group of protists have flagella with many short hair-like structures along the length of the flagella. Diatoms are a single-celled algae with a unique silicon-based cell wall. Other articles where Stramenopiles is discussed: protozoan: Annotated classification: Stramenopiles Group consists of 4 heterotrophic clades and 15 predominantly autotrophic clades and contains many examples of secondarily-derived heterotrophs; in autotrophic groups, fucoxanthin is the dominant accessory pigment. The Kareniaceae group within a clade consisting of haptophytes and stramenopiles, this clade is supported by unique sequence characteristics. Microscopic and floating (about the size of a human red blood cell) Oval or elliptical shape, single cell alga; Has two hair-like short tails used for swimming and to attach to things, two saddle-shaped chloroplasts; Often blooms in large numbers Neighboring taxonomic group: Based on the phylogenetic analysis with 18S rRNA, oomycetes are more related to Heterokontae which contain diatoms and golden-brown algae 2. Many important photosynthesizers are stramenopiles and not all stramenopiles are single-celled. Difference between Oomycetes and True Fungi (1). Simpson, Y. Eglit, in Encyclopedia of Evolutionary Biology, 2016. A ‘hairy’ flagellum is often paired with a shorter, smooth flagellum. Stramenopiles. 3) are a remarkably diverse, monophyletic group that includes: planktonic diatoms, small single-celled or colonial freshwater protists (golden algae), large multicellular marine seaweeds (brown algae), and water molds, which include the pathogen responsible for the potato blight that drove millions of people in Ireland hungry in the nineteenth century. Hyphal architecture: Aseptate and coenocytic tubular hyphae Oomycetes: 1. Ø Both groups produce spores as a mode of reproduction. The front flagellum has tiny, three-part forked brstles running along each side (called mastigonemes). While some lack cell walls, others have scales. Unique Characteristics: Our example is a Trypanosoma ... Stramenopiles 1. 2. This flagellum beats out a water current which moves the … The other subgroup of chromalveolates, the stramenopiles, includes photosynthetic marine algae and heterotrophic protists. A group of non-photosynthetic stramenopiles is the Oomycetes, and there are over 600 described species. These organisms share morphological characteristics with fungi, but phylogenetic analysis has shown that they are not closely related. Stramenopiles (also known as heterokonts) usually have a flagellate stage in the life cycle that has a characteristic type of stiff tubular ‘hairs’ arranged in two rows on one flagellum (see Patterson, 1999).These flagellates swim in the direction the hair-bearing flagellum is pointing. Stramenopiles (Fig. Ø Both groups undergo sexual reproduction. The stramenopiles include the golden algae (Chrysophyta), the brown algae (Phaeophyta), and the diatoms (Bacillariophyta).Stramenopiles have chlorophyll a, chlorophyll c 1 /c 2, and fucoxanthin as photosynthetic pigments.Their storage carbohydrate is chrysolaminarin. The unifying feature of this group is the presence of a textured, or “hairy,” flagellum. 2 In the petH phylogeny, at least 5 isoforms were recovered for Karenia. Stramenopiles have two flagella of different length, one at the front of the cell, and one attached further back. Physical Characteristics. Many stramenopiles also have an additional flagellum that lacks hair-like projections (Figure 9).
