Which of the following structure is not an example of asexual reproduction?
Answer & explanation
Correct answer: option 3

Option (1) Conidia — A structure of asexual reproduction. Asexual spores of Penicillium.
Option (2) Buds — A structure of asexual reproduction. Hydra forms buds that grow into new individuals.

NCERT Extract (Pre-rationalised edition, Chapter 1, Reproduction in Organisms):
Asexual Reproduction – “… Members of the Kingdom Fungi and simple plants such as algae reproduce through special asexual reproductive structures (Figure 1.3). The most common of these structures are zoospores that usually are microscopic motile structures. Other common asexual reproductive structures are conidia (Penicillium), buds (Hydra) and gemmules (sponge).”
