In which one pair both the plants can be vegetatively propagated by leaf pieces -
A
Bryophyllum and Kalanchoe
B
Agave and Kalanchoe
C
Asparagus and Bryophyllum
D
Chrysanthemum and Agave
Detailed Solution
In some plants adventitious buds develop on the leaves and can grow into new plants.
In Bryophyllum, buds arise from the notches along the leaf margin; a leaf or a leaf piece placed on moist soil gives rise to new plants.
Kalanchoe (to which Bryophyllum is closely related) is propagated in the same way by its leaves.
So both Bryophyllum and Kalanchoe can be propagated by leaf pieces.
Agave is propagated by bulbils, Asparagus by fleshy roots or crowns, and Chrysanthemum by suckers.
So the pair is Bryophyllum and Kalanchoe.
