Which of the following structure is not an example of asexual reproduction?

Flowers

The correct answer is Option (3) - Flowers

Flowers are the reproductive structures of flowering plants involved in sexual reproduction, where male gametes fertilize female gametes to produce seeds. In contrast, the other options listed (Conidia, Buds, and Gemmules) are all examples of structures involved in asexual reproduction in various organisms.

Gemmules are internal buds found in sponges, serving as a form of asexual reproduction. These buds contain embryonic cells and have the potential to generate an entire new organism.

Conidia are asexual, non-motile spores produced by fungal hyphae.

Buds are growths that develop on the body of organisms capable of asexual reproduction, such as yeast and hydra. These buds can mature into complete organisms and detach from the parent body to exist independently.
