Question
A student is revising Animal Diversity-I: a hydra responds to touch through a diffuse network of neurons rather than a centralized brain. What should the student write in the answer sheet?
Correct Answer: B
nerve net
Cnidarians have a nerve net, a diffuse nervous arrangement suitable for radial animals. It coordinates simple movements and responses without forming a centralized brain. This MCQ belongs to the Cnidaria topic in Animal Diversity-I and is written to test concept understanding rather than memorized wording.
