NEET BIOLOGY

Detailed explanation-1: -Bulbils are the vegetative buds meant for vegetative propagation seen in Agave. Bulbils are small bulb-like structures, in a particular one in the axil of a leaf, which may fall to form a new plant.

Detailed explanation-2: -Agave macroacantha can sexually reproduce by seeds and propagate vegetatively by aerial bulbils and ground-level basal shoots and rhizomes. It forms compact patches apparently generated by the multiplication of ground-level offshoots.

Detailed explanation-3: -Bulbil is a small bulb-like structure produced in the place of a flower or in a leaf axil. It has the ability to develop into a new plant. It is found in Agave, Oxalis, Pineapple, etc.

Detailed explanation-4: -The given figure shows bulbil, the vegetative propagule of the plant Agave. In Agave, bulbils are modified floral buds that develop on the flowering axis. They remain attached to floral axis and germinate. So, the correct answer is ‘Bulbil’.

Detailed explanation-5: -Vegetative propagation is known to be the formation and growth of a new plant by an asexual means or by a fragment of a plant. The propagation takes place without gamete formation and fertilization. Examples of vegetative propagation are the rhizome of ginger, the tuber of the potato, guava tree, etc.
