What does flagellate mean in science?
What does flagellate mean in science?
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. (A flagellum is a hairlike structure capable of whiplike lashing movements that furnish locomotion.)
What is the meaning of flagellated cells?
A flagellate is a cell or organism with one or more whip-like appendages called flagella. The word flagellate also describes a particular construction (or level of organization) characteristic of many prokaryotes and eukaryotes and their means of motion.
What is an amoeba cell?
An amoeba, sometimes written as “ameba”, is a term generally used to describe a single celled eukaryotic organism that has no definate shape and that moves by means of pseudopodia. Pseudopodia or pseudopods are temporary projections of the cell and the word literally means “false feet”.
What is an example of flagellate?

Flagellate/Representative species
Where are flagellates found?
ail marine biotopes
Flagellates are found in ail marine biotopes from the oligotrophic open oceans to eutrophic inshore waters, mud flats, and marshland ditches. Similar biotopes in geographically distant areas are often inhabited by the same morphological species.
What type of bacteria have flagella?
Flagella are usually found in gram-negative bacilli. Gram-positive rods (e.g., Listeria species) and cocci (some Enterococcus species, Vagococcus species) also have flagella. Most of the cocci (e.g. Staphylococci, Streptococci, etc) don’t have flagella so they are non-motile.
Where are flagellated cells found?
A flagellum is a whip-like structure that allows a cell to move. They are found in all three domains of the living world: bacteria, archaea, and eukaryota, also known as protists, plants, animals, and fungi.
What are the characteristics of flagellates?
Flagellates are characterized by the possession of one or more flagella, which are long, tapering, hair-like appendages that act as organelles of locomotion and feeding (Fig. 2.1 A).
Is amoeba a bacteria or virus?
amoeba: A single-celled microbe that catches food and moves about by extending fingerlike projections of a colorless material called protoplasm. Amoebas are either free-living in damp environments or they are parasites. bacteria: (singular: bacterium) Single-celled organisms.
What is the function of amoeba?
hey mate, the answer is as follows : it controls reproduction (it contains the chromosomes) . and many other important functions (including eating and growth). pseudopods – temporary “feet” that the amoeba uses to move around and to engulf food.
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).
What disease does flagellate cause?
Epidemiology. The flagellate protozoan Trypanosoma cruzi is the cause of Chagas’ disease (American trypanosomiasis), a zoonotic infection of approximately 10–12 million persons and over 100 species of wild and domestic animals in the Americas.
