Question

Vegetative propagation in Bryophyllum takes place by
A. Stem
B. Leaf
C. Root
D. None of the above

Answer 1

Hint: Vegetative reproduction is an asexual means of plant propagation that happens in its stalks, rhizomes and stem. This can happen through fragmentation and restoration of particular vegetative portions of plants.

Complete Answer:
Before we find out the correct answers, let us discuss a little more about vegetative propagation. Vegetative reproduction is a sort of asexual generation that provides progeny by any vegetative propagule (roots, suckers, tubers, etc.) without gamete production and propagation of male and female gametes. For example, the rhizome of ginger, Tuber of potatoes.

Bryophyllum daigremontianum arises from a single stem that is coated from top to base with large, blue-green scales. The plantlets that develop on the sides of each leaf fall quickly and root anywhere they land. This plant’s capacity to generate quickly is where it receives its signature. It is more perfect for container planting than landscape sowing because it can be challenging to manage in outdoor gardens.

Bryophyllum propagates plantlets along the borders of its leaves. When they grow, they drop off and root in any proper soil under thereby fulfilling the purpose of vegetative reproduction.

Thus, the correct answer is option (B), 'Leaf'.

Note: Bryophyllum is applied in ethnomedicine for the practice of wounds, earache, diarrhoea, ulcer, pest bites, and Lithiasis. It has been reported in Trinidad and Tobago as being applied as a legendary therapy for hypertension and the medication of Kidney stones.
