protozoans are tiny,single celld organism. they are very small and it can be only seen trhough a microscope. poriferans are the simplest of the many celled animals their bodies are made up of hollow tubes with pores or openings on the side

An animal derived from only two germ layers are called diploblastic animals. Eg: Poriferans, Coelenterates.
They reproduce asexually by spores and budding
where does the plant reproduce
Porifera is name of phylum and animals belonging to it are called poriferans.
Poriferans (sponges) lack many common characteristics of animals such as a head or a mouth. Typically poriferans do not have eyes, ears, as well as other sense organs. Poriferans do not possess major organs such as heart, stomach, muscles, or even a nervous system.

All poriferans and coelenterates live in water, most of them in sea water, but some in fresh water. Poriferans are bottom-dwellers. Coelenterates can be free-swimming, fixed to the bottom or live in colonies fixed to the bottom, depending on species and face of life.
Poriferans needs organic substances and cnidarians needs of a gastrovascular cavity with openings.
No, poriferans do not have brains or any other organs.

Phylum Porifera sponges have radial symmetry.
Poriferans, or sponges, use the flagella of their individual choanocyte cells in order to generate a current of water that brings in food, in the form of zooplankton and or phytoplankton, as well as to bring in oxygen and other dissolved nutrients, and take away carbon dioxide and other dissolved wastes.
