They reproduce by binary fission. They spend most of their existence moving or feeding. Many parasites that affect human health or economy are flagellates. Flagellates are the major consumers of primary and secondary production in aquatic ecosystems - consuming bacteria and other protists.

How does a flagellate obtain energy?
The majority of species exploiting small particulate food, such as bacteria, small flagellates and ciliates, are essentially filter feeders, creating feed- ing currents by means of the oral ciliary structures and collecting and concentrating particles in the current.
How do protozoa multiply?
Protozoa are unicellular eukaryotic microorganisms lacking a cell wall and belonging to the Kingdom Protista. Protozoa reproduce asexually by fission, schizogony, or budding. Some protozoa can also reproduce sexually. ... The vegetative, reproducing, feeding form of a protozoan is called a trophozoite.
What are the major characteristics of flagellates?
Flagellates (subphylum mastigophora) are single-celled protozoa that move using flagella.
What is flagellation in microbiology?
Flagella (singular, flagellum) are the locomotory structures of many prokaryotes. The flagellum functions by rotation to push or pull the cell through a liquid medium.
Where does the flagellate live?
Flagellates are typically found in the large intestine and the cloaca, although occasionally they may be found in the small intestine in low numbers.
How do protozoans move and reproduce?
Most protozoa reproduce asexually by cell division producing two equal or sometimes unequal cells. ... Many protozoa also reproduce asexually by budding. In this process, daughter nuclei produced by mitotic division migrate into a cytoplasmic protrusion (bud) which is ultimately separated from the mother cell by fission.
What protozoa reproduce?
Protozoa, like all other organisms, reproduce. The most common form of reproduction in protozoa is asexual binary fission. In other words, a single organism will divide into two equal organisms.
Can protozoa reproduce without a host?
Some protozoa have complex life cycles requiring two different host species; others require only a single host to complete the life cycle. A single infective protozoan entering a susceptible host has the potential to produce an immense population.
Is flagellate a protozoa?
flagellate, (subphylum Mastigophora), any of a group of protozoans, mostly uninucleate organisms, that possess, at some time in the life cycle, one to many flagella for locomotion and sensation. ... Many flagellates have a thin, firm pellicle (outer covering) or a coating of a jellylike substance.
Are flagellates harmful to humans?
In humans and other mammals, several widespread diseases are caused by flagellates. Perhaps the most widespread is giardiasis caused by the intestinal parasite Giardia lamblia, with symptoms such as diarrhea (water and nutrient loss) and painful abdominal cramps.
Is amoeba a flagellate?
The amoeba, Naegleria gruberi, changes from the amoeboid form to a free-swimming flagellate form in about two hours after it is transferred to distilled water. The change involves the development of a strong polarity and an alteration in the character of the membrane.
What do flagellates do?
Flagellates are single-celled protists with one or more flagella, whip-like organelles often used for propulsion. The flagella is used for movement through the liquid. Some flagellates live as colonial entities, while others function as a single cell.
What are the function of flagella?
Flagellum is primarily a motility organelle that enables movement and chemotaxis. Bacteria can have one flagellum or several, and they can be either polar (one or several flagella at one spot) or peritrichous (several flagella all over the bacterium).
Are flagellates prokaryotic or eukaryotic?
Flagella are primarily used for cell movement and are found in prokaryotes as well as some eukaryotes. The prokaryotic flagellum spins, creating forward movement by a corkscrew shaped filament.
