- What function do amoeboid cells serve?Differentiate between Phylum Porifera and Clade Eumetazoa. A)Poriferans are only haploid during their life cycle, whereas eumetazoans are diploid with haploid sex cells at various stages of their life cycle. B)Poriferans have mobile gametes while eumetazoans do not. C)Poriferans invert during their development whereas eumetazoans do not invert at any time during their life cycle. D)The various cells types of Poriferans do not form permanent associations into true tissues during their life cycle, whereas Eumetazoa possess true, stable tissues. E)Poriferans have only one kind of cell during their life cycle whereas Eumetazoa have many kinds of cells throughout their life cycle.The dauer stage of worm development occurs: 1) when there is ample food 2) when there is excess food 3) when the strain of bacteria used to feed the worms is changed 4) when there is too little food
