BIOL 181 EXAM 3 QUIZ 2024 A + graded 100% verified Diploblastic - answerhaving two germ layers; ectoderm and endoderm Triploblastic - answerhas three germ layers: the ectoderm, endoderm, and mesoderm. spiral vs radial cleavage - answerIn spiral cleavage, the division planes are not at 90 degree angles, resulting in blastomeres that are not aligned directly over or beside one another. Radial Cleavage: occurs such that the resulting daughter cells are located exactly on top of one another. ...
