Which statement accurately describes the typical coelom formation process in protostomes and deuterostomes?
A: In protostomes, the coelom forms from solid masses of mesoderm splitting (schizocoelous), while in deuterostomes, it forms from folds of the archenteron (enterocoelous).
B: Both protostomes and deuterostomes form their coelom from outpocketings of the archenteron.
C: Protostomes develop a coelom from mesodermal outpocketings, and deuterostomes form it from splitting solid mesoderm.
D: Only protostomes develop a true coelom; deuterostomes are acoelomate.
Explanation
The 'Coelom Formation' section and Figure 32.10 b explain that in protostomes, the coelom forms from splits in solid masses of mesoderm schizocoelous , while in deuterostomes, it forms from outpocketings of the archenteron enterocoelous .
