Question

Difference between Hydra and planeria

Answer 1

Explanation:

Hydra: Observations of Hydra show feeding behavior, detailed microscopy of stinging cells used in captur- ing prey, two digestive processes (cellular and extracellular), locomotion, reproduction by budding, development of sex organs, and symbiotic guests, both external and internal.

Planaria: The cross-eyed flatworm, Planaria, is both scavenger and predator depending upon opportunity. Observations show food-seeking behavior, the flatworm’s feeding method, locomotion (produced by a carpet of cilia), internal anatomy, and reproduction through the remarkable process of regeneration.
