7 lis 2023 · A flagellum or flagella is a lash or hair-like structure present on the cell body that is important for different physiological functions of the cell. The term ‘flagellum’ is the Latin term for whip indicating the long slender structure of the flagellum that resembles a whip.
25 lis 2014 · Learn how eukaryotic flagella (or cilia) evolved from a common ancestor and how they vary in form, function, and protein content across different taxa. Explore the roles of flagella in motility, sensory perception, and secretion in protists and animals.
Eukaryotic flagella—those of animal, plant, and protist cells—are complex cellular projections that lash back and forth. Eukaryotic flagella and motile cilia are identical in structure, but have different lengths, waveforms, and functions.
27 kwi 2017 · 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).
27 mar 2024 · Flagella are slender, whip-like appendages extending from certain cells, primarily serving the purpose of motility and, in some organisms, functioning as sensory organelles. They are found across various organisms, from bacteria and archaea to eukaryotic cells.
22 paź 2024 · Explore the intricate structure and diverse types of flagella, highlighting their essential role in cellular movement and sensory functions.
Recent structural studies—combining X-ray diffraction and single particle image analysis by cryo-EM—have given insights into the molecular mechanisms of self-assembly, supercoiling and polymorphic ability and open the way for construction of various flagella-based systems for applications in vaccination, bio- or nanotechnology.
