Answer 1

$<b>$a) Planaria gets split into 2 parts and it regenerates due to its special regenerative cells.

b)When the mature filament of a spirogyra attains considerable length the filament breaks up into smaller fragments or pieces, and each fragment grows into a new filament/individual.

c)On maturation sporangia of rhizophus bursts. ... When the sporangia of Rhizopusbursts upon maturation, the spores spread out. So, with the help of different agents, the spores are transferred to various places and when they land on a particular surface, new organism (mycelium) starts growing.
