Marine bacteria's mealtime dash is a swimming success

...or studying marine bacteria in the lab by using microfluidic technology. P. haloplanktis is a rapid swimmer, propelling itself by a single rotating flagellum in bursts of speed up to 500 body lengths per second. (The fastest land animal, the cheetah, travels at bursts of speed up to 30 body lengths per seco...

Genome of marine organism tells of humans' unicellular ancestors

...genome is sequenced. The cells are egg-shaped with a single long tail or flagellum at one end surrounded at its base by a collar of tentacles - choano comes from the Greek word for collar - that capture bacteria. The flagellum propels the choanoflagellate through the water and also washes bacteria tow...

Microscopic 'clutch' puts flagellum in neutral

BLOOMINGTON, Ind. -- A tiny but powerful engine that propels the bacterium Bacillus subtilis through liquids is disengaged from the corkscrew-like flagellum by a protein clutch, Indiana University Bloomington and Harvard University scientists have learned. Their report appears in this week's Sc...

Flagellum in Biological Definition

Flagellum

A flagellum (plural, flagella) is a whip-like organelle that many unicellular organisms, and some multicellular ones, use to move about. They may also be involved in other processes. The name actually covers three different structures, found in each of the three domains. Bacterial flagell...

Bacterium

...a distinctive helical body that twists about as it moves. Bacterial flagella are arranged in many different ways. Bacteria can have a single polar flagellum at one end of a cell, or they can have clusters of many flagella at one end. Peritrichous bacteria have flagella scattered all over the cell. Many...

...ular roots. These form a primary component of the cytoskeletal structure, and are often assembled over the course of several cell divisions, with one flagellum retained from the parent and the other derived from it. Centrioles may also be associated in the formation of a spindle during nuclear division. So...

Fungus

...ans of classifying fungi, but are now classified with their ancestral group. Except among the chytrids, where spores are propelled by a posterior flagellum , all fungal spores are non-motile. They develop into new mycelia, which invade some substrate and repeat the life cycle. These may become very large,...
