A long cellular appendage specialized for locomotion. In eukaryotes, the flagellum is formed from a core of nine outer doublet microtubules and two inner single microtubules, surrounded by plasma membrane. In prokaryotes, microtubules are absent.
This is a specialized tail-like structure used to help the cell move.
structure that protrudes from the cell membrane and makes wavelike movements. Classified by length and number per cell, flagella are long and few. A single flagellum propels sperm. Structurally flagella consists of microtubules arranged in a "9 + 2" array.
fine, long threadlike organelles protruding from the surface of a cell that are capable of rotary motion that propels cells. J K Y Z
whip-like growths used by diatoms and dinoflagellates to move in the water.
a cellular appendage that enables cells to have motility
long cell extensions that function in swimming
Elongated appendages of certain cells used in locomotion.
Long, flexible, helical protein structures that extend from the surface of the cell. Rotation of flagella in one direction results in motility, and rotation of flagella in the opposite direction results in tumbling.
hair-like projection used for locomotion in some microorganisms
An organelle that is structurally similar to a cilium but is used to propel a cell through a fluid.
plural of flagellum. Some bacteria have more than one flagellum.
Long hair-like extensions from the cell surface whose movement is used for locomotion.
A whiplike extension of certain cells or unicellular organisms that serves in locomotion.
long, whip-like locomotion organelles found in both prokaryotic and eukaryotic cells; sing.: flagellum. Eukaryotic flagella have an internal arrangement of microtubules in a 9 + 2 array. PICTURE
long, hairlike structures that whip and lash to help flagellates swim
Whip-like tails that are extensions of bacterial cell walls and provide movement.
Long whip-like structures used in cellular locomotion. Usually flagella are not very numerous, cells have from one to four. Flagella are composed of microtubules.
Fine, hair like structures of many free-living eucaryotic cells, primarily used for locomotion
(singular, flagellum) Long, whip-like cell extensions, made of microtubules, that help the cell move. Only one or a few flagella will occur on any given cell. The tail of a sperm cell is a flagellum that enables it to swim to an unfertilized egg.
