The tip links are made up of nearly vertical fine filaments that run upward from the top end of a shorter stereocilia to its taller neighbor.

Stamens of a Hippeastrum with white filaments and prominent anthers carrying pollen

Most disperse their pollen when the stamens are mature and their filaments straighten explosively, a peculiar and conspicuously specialised mechanism.

The filaments of the stamens are white, the anthers and pollen being yellow.

There is depolymerization and reorganization of actin filaments, within the pollen cytoskeleton.

Seeds were borne on one side of variably branched or fused structures, and microsporangia containing pollen were borne in clusters at the tips of slender filaments.

The pollen is blue but the filaments of the stamens remain red, contrasting against the blue flowers.

Also, the stamens, that may contain nectar discs, have distinct glabrous filaments that come in 1-2 whorls and in numbers equaling or twice the number of petals ; the tricolporate pollen is contained within 2 locules of the anthers that open longitudinally along slits.

At the time, Edison was investigating why the filaments of his carbon-filament light bulbs nearly always burned out at the positive-connected end.

Small squares of colours and coloured bands stand out against the black background of Composition X as star fragments ( or filaments ), while enigmatic hieroglyphs with pastel tones cover a large maroon mass which seems to float in the upper-left corner of the canvas.

On the inner walls of these chambers are stalked hairs, which when stimulated by the touch of an insect send out delicate filaments by means of which the insect is killed and digested.

Actin filaments are shown in red, microtubules in green, and the cell nucleus | nuclei are in blue. The cytoskeleton ( also CSK ) is a cellular scaffolding or skeleton contained within a cell's cytoplasm and is made out of protein.

# Drawing: The rayon filaments are stretched, known as drawing, to straighten out the fibers

The name Thysanura is derived from the Greek θυσάνος, thysanos for fringe, tassel, bristle and ουρα, oura for tail, a reference to the three fanned out caudal filaments.

In fact, they feed by filtering out zooplankton from the water, using filaments on their gill arches called gill rakers, and in this respect appear similar to the basking shark.

* Tropomyosin is present in smooth muscle, spanning seven actin monomers and is laid out end to end over the entire length of the thin filaments.

The force-producing head domains stick out from the side of the thick filament, ready to walk along the adjacent actin-based thin filaments in response to the proper chemical signals.

Fluorescent derivatives of phalloidin have turned out to be enormously useful in localizing actin filaments in living or fixed cells as well as for visualizing individual actin filaments in vitro.

When calcium is bound to specific sites on TnC, tropomyosin rolls out of the way of the actin filament active sites, so that myosin ( a molecular motor organized in muscle thick filaments ) can attach to the thin filament and produce force and / or movement.

The microscopic " hairs " of these cells are structural protein filaments that project out into the fluid.

Most other primitive feathered dinosaurs have down-like feathers made up of two or more filaments branching out from a common base or along a central shaft.

The central cluster galaxy contains a massive network of spectral line emitting filaments, which appear to be being dragged out by rising bubbles of relativistic plasma generated by the central active galactic nucleus.

Long gaseous filaments made up of threads of gas stretch out beyond the galaxy, into the multimillion-degree, X-ray – emitting gas that fills the cluster.

In the position of the ears were two huge gill-covers, and out of these floated a branching tree of coralline filaments, almost like the tree-like gills that very young rays and sharks possess.

At King's College London, Gosling worked on X-ray diffraction with Maurice Wilkins, analyzing samples of DNA which they prepared by hydrating and drawing out into thin filaments and photographing in a hydrogen atmosphere.

His eyes were threaded by little filaments of red as if tiny veins had burst and flooded blood into them.

The other parts are more stiff and are composed of intermediate filaments and microtubules.

Included matter of a green, golden, red, black or other color or combinations embedded in the chalcedony and disposed in filaments and other forms suggestive of vegetable growth, gives rise to dendritic or moss agate.

The cytosol is a complex mixture of cytoskeleton filaments, dissolved molecules, and water that fills much of the volume of a cell.

The cytosol also contains the protein filaments that make up the cytoskeleton, as well as soluble proteins and small structures such as ribosomes, proteasomes, and the mysterious vault complexes.

Carbon fiber is made by pyrolysis of extruded and stretched filaments of polyacrylonitrile ( PAN ) and other organic substances.

Carbon fibers made from PAN have structure resembling narrow filaments of graphite, but thermal processing may re-order the structure into a continuous rolled sheet.

Another tool for understanding structure formation is simulations, which cosmologists use to study the gravitational aggregation of matter in the universe, as it clusters into filaments, superclusters and voids.

These materials include: silicon, carbon fiber, carbon nanofibers, filaments, carbon nanotubes, SiO < sub > 2 </ sub >, silicon-germanium, tungsten, silicon carbide, silicon nitride, silicon oxynitride, titanium nitride, and various high-k dielectrics.

Three different heating techniques are used in actual pyrolyzers: Isothermal furnace, inductive heating ( Curie Point filament ), and resistive heating using platinum filaments.

Nuclei are stained blue with DAPI, microtubles are marked green by an antibody and actin filaments are labelled red with phalloidin.

Heated electrodes or hot cathodes, frequently called filaments, are much more common.

In practice, astronomers observe that the Universe has heterogeneous structures up to the scale of galactic superclusters, filaments and great voids, but becomes more and more homogeneous and isotropic when observed on larger and larger scales, with little detectable structure on scales of more than about 200 million parsecs.

There appear to be mechanisms by which an external chemotactic gradient is sensed and turned into an intracellular PIP3 gradient, which results in a gradient and the activation of a signaling pathway, culminating in the polymerisation of actin filaments.

The growing distal end of actin filaments develops connections with the internal surface of the plasma membrane via different sets of peptides and results in the formation of pseudopods.

Although crochet may be done with ribbons, metal wire or more exotic filaments, most yarns are made by spinning fibers.

The active regions involve all the phenomena directly linked to the magnetic field, which occur at different heights on the Sun's surface: sunspots and faculae, happening in the photosphere, spicules, Hα filaments and plages in the chromosphere, prominences in the chromosphere and transition region, and flares and coronal mass ejections happening in the corona and chromosphere, but if flares are very violent can perturb also the photosphere and generate a Moreton wave, as described by Uchida.

On the contrary, quiescent prominences are large, cool dense structures which are observed as dark, " snake-like " Hα ribbons ( filaments ) on the solar disc.

The plasma may cool rapidly in this region ( for a thermal instability ), creating dark filaments in the solar disk or prominences off the limb.

Filament cavities are zones which look dark in the X-rays and are above the regions where Hα filaments are observed in the chromosphere.

This oil can contaminate surfaces inside the chamber or upon contact with hot filaments or electrical discharges may result in carbonaceous or siliceous deposits.

In 2011, Richard Hoover, an astrobiologist at the U. S. Space Flight Center in Alabama, claimed that filaments and other structures in rare meteorites appear to be microscopic fossils of extraterrestrial beings that resemble cyanobacteria — a phylum of photosynthetic bacteria.
