Question

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

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

Answer 1

Answer: (B)

Sporulation

Budding is a type of asexual reproduction which do not involve fusion of gametes. A new organism develops from an outgrowth or bud due to cell division at one particular site. The bud remains attached to the parent plant and separates after it gets mature. It leaves a scar at the point of separation. The newly developed organism is a clone to its parent cell.

Sporulation is the process of production of spores which germinates under favorable condition. During favourable condition the encysted amoeba divides by multiple fission and produces pseudopodiospores. This phenomenon is known as sporulation. In order to survive, the unfavorable condition amoeba develops a tough wall around it known as cyst. When the favorable condition approaches the cyst wall bursts out, and the spores are released in the surrounding medium to grow up into many amoebae.

Fragmentation is a mode of asexual reproduction which involves breaking the parent body into several fragments and each fragment develops into a new individual.

Regeneration is the process of development of lost or damaged part.

So, the correct answer is option B.
