A student is revising Animal Diversity-I: internal partitions divide the coelom of an earthworm into segmental compartments. What should the student write in the answer sheet?

Septa are internal walls between segments in many annelids. They divide the coelom and help localize muscular action during movement. This MCQ belongs to the Annelida topic in Animal Diversity-I and is written to test concept understanding rather than memorized wording.
