Which statement correctly distinguishes schizocoelomates from enterocoelomates?
ASchizocoelomates lack mesoderm, whereas enterocoelomates are triploblastic.
BIn schizocoelomates the coelom arises by mesodermal splitting, whereas in enterocoelomates it arises as outpocketings of the gut.
CSchizocoelomates are always diploblastic, whereas enterocoelomates are triploblastic.
DEnterocoelomates have pseudocoel, whereas schizocoelomates have true coelom.
Answer & Solution
Correct answer: B. In schizocoelomates the coelom arises by mesodermal splitting, whereas in enterocoelomates it arises as outpocketings of the gut.
The key distinction is the mode of coelom formation. In schizocoely, mesoderm splits to form the coelomic cavity; in enterocoely, the cavity develops as outpocketings from the embryonic gut. Both are forms of true coelom, so options A, C, and D are incorrect.
