Question

If Hydra is cut into two pieces, the posterior piece will develop

• A. Mouth at both ends
• B. No mouth, pedal disc
• C. Mouth at posterior and pedal disc at anterior ends
• D. Mouth at anterior end

Answer 1

The correct option is D Mouth at anterior end

If a piece is cut from the gastric region of Hydra, it regenerates distal structures at its distal end and proximal structures at its proximal end. If Hydra is cut into two pieces, the posterior piece will develop mouth at anterior end.
