Question

Vegetative reproduction occurs by bulbils in the
(a) Agave
(b) Colocasia
(c) Zingiber
(d) Vallisneria

Answer 1

Hint: An asexual method of plant reproduction that may occur in its leaves, roots, and stems. It is a natural process by the plant by the involvement of a single parent. Naturally, they are done with help of vegetative propagules.

Complete answer:
Bulbils are a little bulb-like structure which can be removed to make a replacement plant. Agave can sexually reproduce by seeds and vegetatively by aerial bulbils and ground-level based shoots and rhizomes.

Additional Information:
 -Colocasia reproduces sexually by seeds and vegetatively by corms, tubers, and root suckers. Zingiber reproduces vegetatively by aromatic articulated rhizomes. Vallisneria reproduces vegetatively through runners.
-Vegetative reproduction can be both natural and artificial.
Natural Vegetative propagation occurs with the help of vegetative propagules naturally, while Artificial vegetative propagation can occur by the influence of a man like layering, grafting, cutting, etc.
-vegetative propagules play a vital role in propagation. For example, Bulbil, rhizome, bulb, etc.
-The meristem tissue has the ability of continuous division which allows for vegetative propagation to occur.
-Another important ability that permits for vegetative propagation is the ability to develop adventitious roots which arise from other vegetative parts of the plants like the stem or leaves. These roots leave the event of the latest plants from body parts from other plants.
So, the correct answer is ‘‘Agave”.

Note: Vegetative reproduction occurs with the help of vegetative propagules and is of two types, that is, natural and artificial. During a natural vegetative propagation involvement of a single parent is noticed while in the case of artificial, both 1 parent and 2 parent involvement are noticed.
