Question

Adventitious buds at the leaf notches help to propagate the plant of
A. Potato
B. Agave
C. Bryophyllum
D. Cactus

Answer 1

Vegetative propagation is the asexual type of breeding in plants. This takes place through regeneration, fragmentation of some of the vegetative parts of plants. Plants propagate through leaves, offset, tubers, buds etc. The leaves of the plant are used for natural asexual reproduction. On the edge of the leaf gap, there is an epiphyllous bud. These shoots sprout and new plants emerge as their leaves fall to the ground.

Complete answer:
Potato is propagated huge by a vegetative method. Potato has nodes /eyes on its surface body from which the new extensions/birth takes place. Potato is not propagated by the leaf notches. So the option (A) is incorrect.
Agave belongs to the family Asparagaceae. They reproduce sexually by seeds and vegetatively by bulbils. The uncovering of the rosette shows that they derived from the vegetative shoot. They specify rhizomes in their base. Vegetative propagules of agave are bulbils. So the option (B) is incorrect.
The accumulation of plants which take place by the growing part of plants like a leaf, flower, stem, or fruit known as vegetative propagation. Bryophyllum is a set of plant species. Which belongs to the family Crassulaceae. Bryophyllum is growing vegetatively by leaves. The leaves of Bryophyllum process a notch. When the leaves fall on the soil, especially moist soil, it germinates the flower. Notch has a metastatic character( continuously dividing) ability to shoot up into new plants because it has adventitious roots. So the option (C) is correct.
There is a various method to propagate cactus which includes division, by seedling, cutting etc. It depends on the type of plant you have. So the option (D) is incorrect.

Hence, the correct answer is option (C).

Note: Bryophyllum is originating, and adventitious roots formed in the leaf notches of Bryophyllum calycinum. These plants are the rise from continuous division(mitosis) of meristematic tissue in notches in the leaves of the Bryophyllum. Notching is a method that inspires a fiddle leaf multiple to branch doesn’t involve detaching any height off the plant. There are two types of notching.
