Question

Regeneration capability of Hydra is

• A. Maximum in oral region
• B. Minimum in middle region
• C. Maximum in basal region
• D. Equal in all the regions

Answer 1

The correct option is D Equal in all the regions

Regeneration capability of Hydra is equal in all the regions because when a hydra is cut into segments, each segment, if large enough, will grow into an individual hydra sized relative to the size of the segment. Any fragment larger than a few hundred epithelial cells has the capacity to regenerate. Stem cells in the hydra supports its efficient regenerative ability.

So, the correct answer is 'Equal in all the regions'
