Question

Bryophyllum can be propagated vegetatively by
A. Stem
B. Root
C. Leaf
D. Flower

Answer 1

In several parts of the tropics and subtropics, bryophyllum are naturalised and deliberately cultivated as a vegetative reproductive plant for their beauty or interesting reproduction. These plantlets emerge from meristematic-type tissue mitosis in notches in the leaves.

Complete Answer:
- Vegetative propagation is an asexual method of reproduction that only occurs in plants by vegetative propagation.Bryophyllum can be replicated using either a portion of its stem or its leaves by vegetative propagation.
- In their margins, the leaves of a bryophyllum plant have unique kinds of birds, or these terms can be distinguished from the leaves that fall to the ground and then go to grow new plants of bryophyllum.
- Along with the leaf, the birds can also drop to the ground and then go to grow new plants. Sometimes we can see new plants right before a leaf drops off from a biofilm plant. If such a mature leaf of the bryophyllum plant falls on the ground, then each plantlet can develop into a new plant.
- The most striking characteristic of this plant is that it was given the common name of Mother of Thousands. The plant's leaves and stems are green and fleshy and coated with a shiny wax coating. The entire plant is a major water reservoir, preventing water loss by evaporation by the waxy layer. Hence, Bryophyllum tolerates drought well. Its entire metabolism is actually adapted to drought.
- The plant effectively keeps its breath throughout the day, when it is warm, and thus protects itself from water loss by evaporation. The plant then breathes at night, gathering carbon dioxide in a form linked to malic acid. It then uses this carbon dioxide for photosynthesis the next day. This particular kind of photosynthesis is known as crassulacean acid metabolism, which is present in many cacti and succulents.Bryophyllum can also flower towards winter, when the nights become longer than the days.

The correct answer is option (C) Leaf.

Note:Bryophyllum pinnatum is widely used in the ayurvedic medicine system as an astringent, analgesic, carminative and often helpful for diarrhoea and vomiting. In all the hot and moist areas of India, it is naturalised.
