Among protoctists and microscopic animals, a flagellate is an organism with one or more flagella. Some cells in other animals may be flagellate, for instance the spermatozoa of most animal phyla. Flowering plants do not produce flagellate cells, but ferns , mosses , green algae , and some gymnosperms and closely related plants do so. [ 2 ]
Protozoa (sg.: protozoan or protozoon; alternative plural: protozoans) are a polyphyletic group of single-celled eukaryotes, either free-living or parasitic, that feed on organic matter such as other microorganisms or organic debris. [1] [2] Historically, protozoans were regarded as "one-celled animals".
A flagellum (/ f l ə ˈ dʒ ɛ l əm /; pl.: flagella) (Latin for 'whip' or 'scourge') is a hair-like appendage that protrudes from certain plant and animal sperm cells, from fungal spores (), and from a wide range of microorganisms to provide motility.
Protozoa are largely defined by their method of locomotion, including flagella, cilia, and pseudopodia. [35] While there has been considerable debate on the classification of protozoa caused by their sheer diversity, in one system there are currently seven phyla recognized under the kingdom Protozoa: Euglenozoa , Amoebozoa , Choanozoa sensu ...
Breviatea, a small class [a] related to animals, fungi and amoebozoans, is composed of anaerobic amoeboflagellates with two flagella. [13] [14] Percolozoa contains amoeboflagellates with lobose pseudopods, but are differentiated by their flat mitochondrial cristae, not tubular as in Amoebozoa.
Bodo saltans (alternatively known as Pleuromonas jaculans) is a free-living nonparasitic species of kinetoplastid flagellated phagotrophic protozoa that feed on bacteria. [1] Bodo saltans cells have been reported in freshwater and marine environments. Bodo saltans is a single-celled bean-shaped organism 4 to 5 micrometers in length. It has two ...
These protists are equipped with one or more whip-like appendages called cilia, undulipodia or eukaryotic flagella, [b] which enable them to swim or glide freely through the environment. Flagellates are found in all lineages, reflecting that the common ancestor of all living eukaryotes was a flagellate.
A typical example of a ciliated microorganism is the Paramecium, a one-celled, ciliated protozoan covered by thousands of cilia. The cilia beating together allow the Paramecium to propel through the water at speeds of 500 micrometers per second.
