Question

Under unfavourable conditions, a sclerotium is formed by

• A. Rounding of myxamoebae
• B. Rounding of Plasmodium
  
• C. Thickening of sporangium
• D. Plasmotomy

Answer 1

Answer: (B)

Rounding of Plasmodium

Under unfavourable conditions such as drought or too much cold, the Plasmodium divides to form many multinucleate cysts. Sometimes even whole plasmodium forms a hard dormant structure called sclerotium. On the return of favourable conditions, the cyst or the sclerotium liberates the multinucleate diploid Plasmodium.

So, the correct answer is 'Rounding of Plasmodium'
