Detailed explanation-1: -Flagella are microscopic hair-like structures involved in the locomotion of a cell. The word “flagellum” means “whip”. The flagella have a whip-like appearance that helps to propel a cell through the liquid. Some special flagella are used in few organisms as sensory organs that can sense changes in pH and temperature.
Detailed explanation-2: -The little whip-like structures that help prokaryotic cells move are called flagella. The flagella spin around and this helps to move the prokaryotes, like bacteria, along.
Detailed explanation-3: -Eukaryotes have one to many flagella, which move in a characteristic whiplike manner. The flagella closely resemble the cilium in structure.
Detailed explanation-4: -Based on their arrangement, bacteria are classified into four groups: monotrichous (having one flagellum), amphitrichous (single flagellum at both ends), lophotrichous (numerous flagella as a tuft), and peritrichous (flagella distributed all over the cell except at the poles).
Detailed explanation-5: -Flagella are primarily used for cell movement and are found in prokaryotes as well as some eukaryotes. The prokaryotic flagellum spins, creating forward movement by a corkscrew shaped filament. A prokaryote can have one or several flagella, localized to one pole or spread out around the cell.
