Something attached by its base, e.g. an anther attached to the filament. Compare dorsifixed. basipetal Developing sequentially from the apex toward the base (i.e. with the youngest toward the base), e.g. of flowers in an inflorescence. Also, moving from leaves to roots, e.g. of molecular signals in plants. bathyphyll

The word filament, which is descended from Latin filum meaning "thread", is used in English for a variety of thread-like structures, including: Astronomy.
In cosmology, galaxy filaments are the largest known structures in the universe, consisting of walls of galactic superclusters.These massive, thread-like formations can commonly reach 50 to 80 megaparsecs (160 to 260 megalight-years)—with the largest found to date being the Hercules-Corona Borealis Great Wall at around 3 gigaparsecs (9.8 Gly) in length—and form the boundaries between voids ...
Certain bacterial species, such as Paraburkholderia elongata, will also filament as a result of a tendency to accumulate phosphate in the form of polyphosphate, which can chelate metal cofactors needed by division proteins. [2] In addition, filamentation is induced by nutrient-rich conditions in the intracellular pathogen Bordetella atropi ...
Synthetic fibers are produced in longer lengths called filaments. Silk is the only natural fiber that is a filament. The classification of fibers is based on their origin, derivation, and generic types. [9] [67] Certain properties of synthetic fibers, such as their diameter, cross section, and color, can be altered during production. [76]
[1] [2] Each filament contains a capillary network that provides a large surface area for exchanging oxygen and carbon dioxide. Fish exchange gases by pulling oxygen-rich water through their mouths and pumping it over their gills. Within the gill filaments, capillary blood flows in the opposite direction to the water, causing counter-current ...
In molecular biology, an axoneme, also called an axial filament, is the microtubule-based cytoskeletal structure that forms the core of a cilium or flagellum. [ 1 ] [ 2 ] Cilia and flagella are found on many cells , organisms , and microorganisms , to provide motility.
