A student encounters an animal embryo at the eight-cell stage. The four smaller cells that comprise one hemisphere of the embryo seem to be rotated 45 degrees and lie in the grooves between larger, underlying cells (spiral cleavage).
A) This embryo may potentially develop into what kind of animal (base your answer on the animal phylogeny based mainly on morphological and developmental comparisons).
B) If we were to separate these eight cells and attempt to culture them individually, then what is most likely to happen?
