Zygote is made up of one single diploid cell. The diploid cell is made of two haploid cell (one haploid cell of mother and the other one of father). In the later stage of development, zygote divides itself into two , four , eight , sixteen cells and so on till it forms an embryo.

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.
