What happens when:
(a) Accidently, Planaria gets cut into many pieces?
(b) Bryophyllum leaf falls on the wet soil?
(c) On maturation sporangia of Rhizopus bursts?
Answer:
(a) When planaria is cut into many pieces, each piece regenerates into a complete organism.
(b) Bryophyllum leaves have buds along their leaf margins which when they fall on soil, develop into new plants by the process of vegetative propagation.
(c) When the sporangia of Rhizopus bursts upon maturation , it releases spores which, under favourable conditions, germinate and produce new plants.
