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.
they eat tiny organic organisms floating in the water,also by the special cells that are inside the sponge.
Buds formed inside a sponge during asexual reproduction are called gemmules. A sponge forms them during harsh weathers to delay the formation of new sponges until conditions improve.
It takes place inside the cells
The flagella are located on the collar cells inside the sponge. When the sponge takes in water, the flagella reach out and grab the food that is found inside the water.
