Spicules are small, needle-like structures found in sponges, while prominences refer to the large, arching structures seen on the Sun's surface.
Solar flares, spicules, and prominences are driven by the Sun's complex magnetic field and its dynamic plasma. Solar flares occur when magnetic energy is released suddenly, causing explosive bursts of radiation. Spicules are jet-like structures formed by the interaction of magnetic fields with solar plasma, while prominences are large, loop-like structures of cooler plasma suspended in the Sun's atmosphere, often anchored to magnetic regions. These phenomena are all manifestations of the Sun's magnetic activity and the behavior of its ionized gases.
Sponges have collar cells, osculum, and spicules.
No, cnidarians do not have spicules. Spicules are small, needle-like structures made of calcium carbonate or silica that are found in some sponges and echinoderms for support and defense. Cnidarians, such as jellyfish and corals, have a different type of support structure called a mesoglea.
The chromosphere is the layer of the sun that contains jets of rapidly moving gas called spicules. Spicules can extend from the chromosphere into the corona of the sun.
The fourth layer of the Sun is called the chromosphere. It lies above the photosphere and below the corona, extending about 2,000 to 3,000 kilometers in thickness. The chromosphere is characterized by a reddish glow during solar eclipses and is where solar phenomena like spicules and prominences occur. It plays a vital role in the Sun's overall structure and dynamics.
The layer of the sun's atmosphere responsible for flares, spicules, and prominences is the chromosphere. This layer lies above the photosphere and below the corona. It is where these solar phenomena occur due to the intense magnetic activity in the region.

Yes, they are called spicules, not pores or spiracles as many people think.
Spicules provide structural support.
Spicules, like our skeleton, give the sponge structure. Without spicules, Sponge Bob would be Sponge Blob.
Sun spots and prominences.
Prominences can screw up satellites.

Sponges have collar cells, osculum, and spicules.
Sponges have different types of spicules that provide support to their bodies. These can be made of calcium carbonate, silica, or spongin. Calcium carbonate spicules are needle-like and provide rigidity, while silica spicules are more delicate and form intricate structures. Spongin spicules are organic fibers that give flexibility to the sponge's body.
calcarea - have calcite spicules, often have calcite exoskeletons glass sponges - silica spicules, no exoskeleton demosponges - silica spicules, may have exoskeleton, made of aragonite if present
