Question

During favourable condition the encysted amoeba
divides by multiple fission and produces pseudopodio-
spores. This phenomenon is known as

• A. Fragmentation
  
• B. Sporulation
  
• C. Regeneration
  
• D. Budding
  

Answer 1

The correct option is B Sporulation


Sporulation

During unfavorable conditions the amoeba withdraws its pseudopodia and develops a three-layered tough wall around itself which is known as a cyst.

The encysted amoeba divides by multiple fission to form pseudopodiospores.

Upon the return of favourable conditions the cyst wall ruptures and releases the pseudopodiospores which grow into new individuals. This phenomenon is known as sporulation.

Final answer:

(b) Sporulation
