Pore cell
Although they have no true tissues or organs, they are lined inside and out with flattened cells called epithlium. they r made up of more than one cell
A spongocoel is the cavity inside a sponge, such as Grantia, that is lined with flagellated cells and stores the food (tiny particles and bacteria) the sponge receives from filter-feeding. Inside the spongocoel, food particles are trapped on a layer of mucilaginous material and transported into the sponge's cells for digestion.

Digestive System is lined inside by non-keratinised stratified squamous epithelium some of which are ciliated.

Water is brought through cilia-lined pores into the hollow cavity of the sponge. As water passes through the pores, the cilia trap oxygen to breathe
Mucus to be less specific
An insulator or neither. The water inside of the sponge is what would conduct electricity.
The buds formed inside a sponge during asexual reproduction are called gemmules. These structures contain a cluster of cells surrounded by a protective layer and can detach from the sponge to form a new individual under favorable conditions.
It takes place inside the cells
the ditch in the ground and cemented from inside to stop the salinity and water.
