Megascleres, which are large-sized and constitute main supporting framework of sponge body, megascleres make up the main framework of a sponge and are needle-shaped structures while Microscleres, which are smaller in size and occur in the mesenchyme, appear to add structural reinforcement for sponge tissues.
Sponges are invertebrate animals that usually have no body symmetry & never have tissues or organs & it has different kinds of cells & structures for different functions.
Homologous structures (Not to be confused with Homologous pairs)
Cells. Different types of cells have different names. What type of cells are you talking about? Different parts of a body have different types of cells.
millions of different types of T cells
Spicules are tiny structures of hard crystal that give the sponge it's shape. There are many different types of spicules, some examples are; acanthostyles, stongyles, and anatriaenes.

There are different types of cells, but the structures are basically same, with similar organelles and other structures.
What supports a sponge it its agility to love god with all its tentacles, rays, and hole on the bottom of itself.
Sponge
The human body is made up of many different types of structures. In your leg alone there are four bones.
Stinging cells ,tentacles .
We have different structures that perform different functions so the body can be more efficient.

an "amoebocyte" Spicules are the inorganic, needle-like, calcium carbonate or silicate structures that give a sponge its shape and rigidity.
A sponge doesn't have a body temperature, because a sponge doesn't have a body. But how warm or cold you put the sponge under water or any liquid is the temperature of the sponge.
