Answer:
Correct Answer: B
Solution:
Porocytes mean pore cells.
Within the sponge body wall there are special, large and tubular cells, called pore cells or porocytes.
Each porocyte contains a central space communicating with the outside as well as the spongocoel.
These spaces are called ostia or dermal pores or incurrent pores.
These permit water to flow from outside into the spongocoel.
