The glandulo-muscular cells in Hydra are found

• A. In the pedal disc
• B. In the tentacles
• C. In the trunk
• D. None of the above

Answer 1

Answer: (A)

The glando-muscular cells of Hydra are located exclusively in the basal disk. They are derived from the epithelial-muscular cells which have been forced proximally. Hydra when extended, secured by a simple adhesive foot called pedal disc. Glando-muscular cells in this disc secrete a sticky fluid that accounts for its adhesive properties.
Thus, the correct answer is option A.
