Question

Does Hydra have bilateral symmetry?

Answer 1

Symmetry:

Radial, bilateral, and asymmetric symmetry are the three types of symmetry seen in organisms.

1. Radial symmetry is a sort of symmetry in which a plane is passed through the central axis, dividing the organism into two equal halves. Ctenophora and Cnidaria are two phyla that have this form of symmetry.
2. Bilateral symmetry is a sort of symmetry in which the two sides are alike. The body is divided into identical left and right sides in this form of symmetry. The majority of phyla, including annelids, nematodes, Arthropoda, chordates, and others, have this symmetry.
3. Asymmetry is defined as the absence of a specific type of symmetry in organisms. Simple phyla like Porifera demonstrate this.

Final Answer: Hydra is cnidarian, which means it has radial symmetry.
