filament meaning in biology

This term "polarity", in reference to a cytoskeleton filament, does not mean what it did when we discussed polar functional groups earlier in this course. A threadlike structure (as a chainlike series of cells). 1. a delicate fiber or thread. CallUrl('www>sparknotes>comcabartleby>com<107<215>html',0), micro~TildeLink()A solid rod of actin protein in the cytoplasm of almost all eukaryotic cells, making up part of the cytoskeleton and acting alone or with myosin to cause cell contraction.micronutrient ... CallUrl('www>phschool>comhtml',0), ~TildeLink()ous or platelike structure with blood vessels for respiration in waterSource: Noland, George B. There are three types of filaments: microtubules, microfilaments (known as actin filaments), and … a minute, narrow tubelike cell structure composed of a protein similar to actin, occurring singly and in bundles, involved in cytoplasmic movement and changes in cell shape. To learn more about filaments, we'll look at each individual type. (b) Describe its function. Module 23: The Musculoskeletal System. Within the anther reside the microsporangia, which will ultimately develop into pollen grains. They are often bundled together for strength and rigidity. A muscle is a complex unit containing several muscle fasciculus. Intermediate filaments can assemble into large coils made of many strands of filaments to create stronger chains. Learn / Biology / Thin Filament. Examples of intermediate proteins are: desmin, which helps to connect cells to each other in organs like skin; keratin, which makes up hair and nails; and laminin, which is involved in supporting the structure of the nucleus inside cells. CallUrl('learn>genetics>utah>edulearner>orghtml',0), Each micro~TildeLink() is built as a twisted double chain of actin subunits.

The stamen of a flower — the part that produces pollen — consists of a slender stalk, called a filament and an anther.
