Flagellates are actually used by cells and unicellular organisms (protozoa) for motor, sensory and signal transduction And just an extension of a cell or organism. Depending on the organism, the flagella consists of different structures. In bacteria, flagellates are made from the protein flagellin.

Are flagellates protozoa?

flagellates are protozoa There is one or a few long whip-like hairs, called flagella, that are used for locomotion. Lifestyles include autotrophic, heterotrophic, parasitic, and symbiotic.

Are flagellates parasitic?

Flagellates may be solitary, gregarious (Volvox), free-living (Euglena) or parasitic (Disease-causing trypanosomes). Parasitic forms live in the host’s gut or blood. Many other flagellates (Dinoflagellates) live as plankton in both salt and fresh water.

How do flagellates cause disease?

In humans and other mammals, several widespread diseases are caused by flagellates.Perhaps the most common is Giardiasis Caused by the intestinal parasite Giardia, with symptoms such as diarrhea (loss of water and nutrients) and abdominal cramps.

Which protozoa has flagella?

Trypanosomes Belongs to the carnoflagellate phylum. They are a group of flagellated protozoa whose life cycle involves two hosts, an insect vector and a mammalian host. Therefore, the correct answer is option (D).
