Question

Reproduction in Bryophyllum takes place by

• A. Root
• B. Leaf
• C. Stem
• D. None of these

Answer 1

The correct option is B Leaf

Some plants develop adventitious buds on their leaves which get detached and develop new plants. Leaves of Bryophyllum develop small plantlets with adventitious roots along their margins. These get detached and give rise to a complete plant. Thus it is a natural method of vegetative propagation in this plant with the help of leaves. Leaves of some other plants such as Kalanchoe, Begonia and Streptocarpus also develop adventitious buds in their leaves.

In some plants such as tapioca, sweet potato buds present on the roots develop into leafy shoots above ground and adventitious roots at their bases.

Vegetative propagation by stem takes place in mint, onion, garlic, banana etc.

Thus, the correct answer is option B.
