In the collared flagellates, or choanoflagellates, for example, the collar and flagellum operate in feeding. ... The beating flagellum creates a water current, causing water to move through the collar. Particles of food in the current are trapped on the collar and are ingested by pseudopodia at its base.

How do flagellates eat?
In some flagellates, flagella direct food into a cytostome or mouth, where food is ingested. ... Many protists take the form of single-celled flagellates. Flagella are generally used for propulsion. They may also be used to create a current that brings in food.
How does a flagellate obtain energy?
Bacterial flagella are helically shaped structures containing the protein flagellin. ... The movement of eukaryotic flagella depends on adenosine triphosphate (ATP) for energy, while that of the prokaryotes derives its energy from the proton-motive force, or ion gradient, across the cell membrane.
Can flagellates make their own food?
Some flagellates, such as the Euglena, can make food by photosynthesis like plants, while others, such as the Trypanosomes, are parasitic and cause disease. The word flagellate also describes a particular construction and their means of motion.
How do protozoans feed?
Protozoans may take food into the cell at a specific point, such as the cytostome (a well-developed feeding groove), at a particular region of the cell surface, or at any random point of entry. ... Particles of food in the current are trapped on the collar and are ingested by pseudopodia at its base.
How do Amoeboids feed?
The food sources of amoebae vary. ... Amoebae typically ingest their food by phagocytosis, extending pseudopods to encircle and engulf live prey or particles of scavenged material. Amoeboid cells do not have a mouth or cytostome, and there is no fixed place on the cell at which phagocytosis normally occurs.
How do flagella generate cell motility?
How do flagella generate motility? ... -Flagella rotate counterclockwise to propel the cell forward and clockwise to tumble and change direction.
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.
What is the difference between flagellates and dinoflagellates?
Flagellates are commonly identified by whether they have chloroplasts or do not have chloroplasts. Flagellates with chloroplasts are commonly called phytoflagellates, and flagellates without chloroplasts are called zooflagellates. ... Some of the better known and numerous free-living flagellates are the dinoflagellates.
What is a fun fact about flagellates?
Flagellates are cells with one or more whip-like organelles called flagella. Some cells in animals may be flagellate, for instance the spermatozoa of most phyla. Flowering plants and fungi do not produce flagellate cells, but the closely related green algae and chytrids do.
Why is Ingestive feeding important in protists?
Protist Nutrition
Ingestive protists ingest, or engulf, bacteria and other small particles. They extend their cell wall and cell membrane around the food item, forming a food vacuole. ... These protists are important decomposers. Photosynthetic protists use light energy to make food.
Are flagellates free living or parasitic?
Flagellates may be solitary, colonial (Volvox), free-living (Euglena), or parasitic (the disease-causing Trypanosoma). Parasitic forms live in the intestine or bloodstream of the host. Many other flagellates (dinoflagellates) live as plankton in both salt and fresh water.
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.
Are flagellates prokaryotic or eukaryotic?
An example of a eukaryotic flagellate cell is the mammalian sperm cell, which uses its flagellum to propel itself through the female reproductive tract. Eukaryotic flagella are structurally identical to eukaryotic cilia, although distinctions are sometimes made according to function or length.
Are flagella heterotrophic?
The flagellates are a grade of organisation. In addition, alveolates and stramenopiles include heterotrophic flagellates, as do several groups often thought of as algae (dinoflagellates, euglenids, and cryptomonads). ...
