Question

Regeneration occurs in:

• A. Planaria
• B. Lizards
• C. Star fish
• D. All of the above

Answer 1

The correct option is D All of the above

a) Planaria when cut into pieces each piece regenerates into a complete organism. Cells at wound location proliferate and differentiate into new tissues and regenerate the missing parts of the piece of the cut planaria.

b) Lizards have fracture planes that are spaced regularly down the length of the tail at which breaks can occur. This method of survival is used by the lizard to escape while the predator is focused on its moving tail.

c) Starfishes have the ability to regenerate limbs and in some cases even entire bodies.

Thus the correct answer is option D
