Which of the following statements accurately distinguishes protostome and deuterostome development?
A: Protostomes exhibit radial cleavage, while deuterostomes exhibit spiral cleavage.
B: In protostomes, the coelom forms from outpocketings of the archenteron, whereas in deuterostomes, it forms from splits in solid mesoderm.
C: The blastopore develops into the mouth in protostomes and the anus in deuterostomes.
D: Deuterostome development is determinate, while protostome development is indeterminate.
Explanation
The text and Figure 32.10 c clearly state that in protostomes, the mouth forms from the blastopore, while in deuterostomes, the blastopore usually forms the anus and the mouth forms from a secondary opening.
