Question

Type of asexual reproduction found in $Hydra$ is

• A. Binary fission
• B. Gemmule formation
• C. Budding
• D. Sporulation

Answer 1

The correct option is C Budding

Gemmule formation
Gemmules are internal buds in sponges and help in asexual reproduction by giving rise to new individuals when they are released from the parent body.

Sporulation
During unfavorable conditions the $Amoeba$ develops a three-layered tough wall around itself called a cyst. The encysted Amoeba divides by multiple fission to form pseudopodiospores which are released upon the return of favourable conditions and grow into new individuals. This phenomenon is known as sporulation.

Binary fission
Binary fission is a method of asexual reproduction in which the nucleus elongates and divides into two followed by division of cytoplasm, giving rise to two daughter cells. Example $Amoeba$.

Budding
$Hydra$ reproduces asexually by budding. Bud develops externally while being attached to the parent body and detaches itself from the parent body to develop into a new individual.

Final answer
(d). Budding
