Question

Raju found a bryophyllum growing in a nearby ground. He cut off a piece of stem from it and planted it in his garden. But even after a few days, the plant didn't seem to grow. Why do you think that happened?

• A. He used the stem instead of the seed of the plant.
• B. He used stem instead of roots of the plant.
• C. The buds present at the leaf margins are used for vegetative propagation.
• D. The propagation of bryophyllum takes place using leaves.

Answer 1

Answer: (C), (D)

The correct options are
C The buds present at the leaf margins are used for vegetative propagation.
D The propagation of bryophyllum takes place using leaves.

Vegetative propagation is the method of producing a new plant from the vegetative parts of the plant i.e. leaves, stem and roots. In bryophyllum, vegetative propagation takes place through leaves. The leaf in the bryophyllum plant is broad and has notches at its margins.Buds produced in the notches along the leaf margin of bryophyllum fall on the soil and develop into
new plants.
