Spicule shapes and mesh structures are essentially the only variable amongst sponge morphology that can be easily differentiated. Sponges are often described as evolutionary dead ends because there is so little variation possible (comparatively) with simple structures and very limited cell types.
Spicules, like our skeleton, give the sponge structure. Without spicules, Sponge Bob would be Sponge Blob.
One of the largest determining factors in sponge taxonomy is the size, composition, and shape. Sponges are in the Phylum Porifera.
Spicules serve as a internal skeleton, and may also help defend against predators (But don't take my word on it)
They make up the skeleton of the animal.
they provide structure for the sponge
Skeletal support in sponges is accomplished by means of units called spicules. The two types of spicules are megascleres and microscleres. They can be made of proteins or minerals.
One unique characteristic distinguishing animals from members of other kingdoms is animals have more complex and rapid movements. The movement of sponges isn't more complex.
the skeletons can be used as sponges to wash dishes
Amoebas gace rise to sponges since the wall of sponges contain amoebocytes.
No. Sponges are animals and animal cells do not have a cell wall.
Spicules provide structural support.
spongin and spicules are the sponges body support and defence
spicules
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
Sponges have collar cells, osculum, and spicules.

My science teacher said that it is sessile and it reproduces anisexually and some other way
Spicules, like our skeleton, give the sponge structure. Without spicules, Sponge Bob would be Sponge Blob.
Cnidarians do not have spicules. Spicules are commonly found in sponges and it is a simply a skeleton which has very tiny splinters that look like needles.
