Hydra

Vedclass · Answer

(A) Hydra belongs to the phylum $Cnidaria$. It possesses a primitive nervous system consisting of a network of neurons (nerve net) spread throughout the body. However, it lacks a centralized nervous system, such as a brain or distinct nerve cords, which are characteristic of higher animals like flatworms $(Platyhelminthes)$, annelids $(Earthworm)$, and chordates $(Frog$ tadpole). Therefore, among the given options, $Hydra$ is the most primitive organism with a diffuse nerve net rather than a complex nervous system.

Which of the following animals possesses neurons but lacks a nervous system (nerve net/ganglia/brain)?
