A flagellum is a microscopic hair-like organelle used by cells and microorganisms for movement. The word flagellumin Latin means whip, just like the whipping motion flagella (plural) often use for locomotion. Specialized flagella in some organisms are also used as sensory organelles that can detect changes in temperature and pH.
Flagella are filamentous protein structures found in bacteria, archaea, and eukaryotes, though they are most commonly found in bacteria. They are typically used to propel a cell through liquid (i.e. bacteria and sperm). However, flagella have many other specialized functions. Some eukaryotic cells use flagellum to increase reproduction rates. Other...
A flagellum can be comprised of different structures depending on the organism, especially when flagellum from eukaryotes and bacteria are compared. Since eukaryotes are usually complex organisms, the attached flagellum is more complex as well. The flagellum is made up of microtubules composed from a protein called tubulin. Nine microtubule pairs s...
The flagellar structure consists of three different parts: rings embedded in the basal body, a hook near the surface of the organism to keep it in place, and the flagellar protein filaments. Every flagellum has these three things in common, regardless of organism. However, there are four distinct types of bacterial flagellum based on location: A. M...
ATP– Adenosine triphosphate, a small molecule used in cells as a coenzyme that transfers energy.Microtubules– A microscopic tubular structure present in the cytoplasm of cells that helps form the cytoskeleton.Basal body– An organelle that forms the very base of a flagellum; it is similar to a centriole in structure.Brownian motion– The random movement of particles in a fluid (liquid or gas), caused by bumping into other molecules within the same fluid.1. What is the primary function of flagellum? A. Energy production B. Communication C. Locomotion D.Heat production 2. What gives bacterial flagellum energy? A. ATP B. Ion gradients C. Basal bodies D.Flagellin 3. Which of the following is not considered a polar bacterial flagellum? A. Monotrichous B. Amphitrichous C. Lophotrichous D.Peritrichous
Biology is a science, but what exactly is science? What does the study of biology share with other scientific disciplines? We can define science (from the Latin scientia , meaning “knowledge”) as knowledge that covers general truths or the operation of general laws, especially when acquired and tested by the scientific method.
The Bio-Dictionary helps you to understand common terms in biology. Definitions come in the form of a figure with accompanying text, a short video, or both.
