Question

What is the function of the flagella?

Answer 1

Hint: Flagella is a protruding lash-like appendage from the cell membrane. The flagellum (plural form flagella) is primarily a motility organelle. That enables movement and chemotaxis. Bacteria can have one or several flagella.

Complete answer:
Flagella are microscopic hair-like structures. This is involved in the locomotion of the cell. The word flagellum means to whip. In a few organisms, flagellum is used as sensory organs that can sense changes in pH and temperature. Flagella are organelles are defined by function. Three types of flagella are distinguished. Like bacterial, archaeal, and eukaryotic. All these three kinds of flagella can be used for swimming. Archaeal flagella are nonhomologous flagella and bacteria flagella are a coiled thread-like structure. There are many functions of flagella. The flagella help an organism to move from one place to the other. In some organisms they act as sensory organs which detect temperature and pH changes. And some eukaryotes use flagellum to increase reproduction rates. Now it is also discovered that flagella are also used as a secretory organelle. Flagella are a protozoan's characteristic feature. Flagella is seen in different organelle as different structure, mechanism, movement and function.

Note:
Flagella are thread-like structures which help in locomotion in some organisms. They can only be seen under a microscope. In some organisms flagella is used as a sensory organ. When in some instances bacteria senses either the presence of nutrients or harmful conditions in that situation flagella plays a major role. Flagellum is a whip like structure. Flagella are the primary structure for locomotion in most of the organism.
