Flagellated protists
WebFlagellates. Flagellates have one-to-many flagella that function in motility, attachment to a substrate, and also for feeding. They are phylogenetically diverse (Table 1 ), and are the most numerous of the freshwater protists reaching abundances in eutrophic systems that can approach 10 5 cells ml −1 and 10 6 cells cm −3 in the plankton and ...

WebProtists are the eukaryotes that cannot be classified as plants, fungi or animals. They are mostly unicellular and microscopic.Many unicellular protists, particularly protozoans, are motile and can generate movement using flagella, cilia or pseudopods.Cells which use flagella for movement are usually referred to as flagellates, cells which use cilia are … In older classifications, flagellated protozoa were grouped in Flagellata (= Mastigophora), sometimes divided into Phytoflagellata (= Phytomastigina, mostly autotrophic) and Zooflagellata (= Zoomastigina, heterotrophic). They were sometimes grouped with Sarcodina (ameboids) in the group Sarcomastigophora. The autotrophic flagellates were grouped similarly to the botanical schemes used for the corres…

WebOne of the most striking features of many protist species is the presence of some type of locomotory organelle, easily visible under a light microscope. A few forms can move by gliding or floating, although the vast majority move by means of “whips” or small “hairs” known as flagella or cilia, respectively.
