What is the name of the hair like structures on some protozoans that are used for movement?
Cilia – tiny hair like structures that cover the outside of the microbe. They beat in a regular continuous pattern like flexible oars. Flagella – long thread-like structures that extend from the cell surface. The flagella move in a whip-like motion that produces waves that propel the microbe around.
Which protist has hairy like structures called cilia?
amoebas. Protists with complex bodies covered with a hair-like structure that is known as cilia are called amoebas. Amoebas are unicellular organism that gives an individual or an organism motility.
How do protozoa breathe?
Aerobic protozoans As in the cells of animals, plants, and fungi, their respiration is based on oxidation (with molecular oxygen, O2) of the six-carbon glucose molecule, resulting in the formation of carbon dioxide molecules and water.
What are the whip like hair on microbes called?
Ciliates are microorganisms with small, hair-like projections on their surface called cilia. The cilia can be very numerous, covering the entire surface of many microbes, or several can be fused together to form a bundle. Cilia beat in a coordinated fashion to propel the organism through the water.
Who are useful protozoa?
Some protozoans live in the body of other organisms and help them. Termites, for example, have protozoans living in their body. The protozoans digest the cellulose in the wood eaten by termites and convert it into carbohydrates that the termites can use.
Where does protozoa live in human body?
Protozoa that live in the blood or tissue of humans are transmitted to other humans by an arthropod vector (for example, through the bite of a mosquito or sand fly). The protozoa that are infectious to humans can be classified into four groups based on their mode of movement: Sarcodina – the ameba, e.g., Entamoeba.
Is bacteria smaller than a virus?
Viruses are even smaller than bacteria and require living hosts — such as people, plants or animals — to multiply. Otherwise, they can’t survive. When a virus enters your body, it invades some of your cells and takes over the cell machinery, redirecting it to produce the virus.
Which is larger a virus or bacteria?
Viruses are much smaller. The largest of them are smaller than the smallest bacteria. Unlike bacteria, viruses can’t survive without a host. They can only reproduce by attaching themselves to cells.
How do you know if it’s viral or bacterial?
Diagnosis of Bacterial and Viral Infections But your doctor may be able to determine the cause by listening to your medical history and doing a physical exam. If necessary, they also can order a blood or urine test to help confirm a diagnosis, or a “culture test” of tissue to identify bacteria or viruses.
What viruses are contagious?
Common examples of contagious viral diseases include the flu, the common cold, HIV, and herpes. Other types of viral diseases spread through other means, such as the bite of an infected insect.
