Which of the following is not a vegetative propagation ?

Bud of Hydra

The correct answer is Option (4)- Bud of Hydra

Members of the Kingdom Fungi and simple plants such as algae reproduce through special asexual reproductive structures . 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). While in animals and other simple organisms the term asexual is used unambiguously, in plants, the term vegetative reproduction is frequently used.

In plants, the units of vegetative propagation such as runner, rhizome, sucker, tuber, offset, bulb are all capable of giving rise to new offspring . These structures are called vegetative propagules.

Buds of Hydra are asexual reproductive structures .
