Plants reproduce asexually through their vegetative parts. This is called vegetative propagation.

Vegetative propagation occurs naturally in plants through various methods, such as fragmentation, budding, and spore formation.

Budding is a form of asexual reproduction where new individuals arise from a parent plant that develops an outgrowth, which eventually separates to form a new individual. (correct)

Gemmules are internal buds formed in sponges, consisting of dormant cells that can develop into a new organism. (correct)

Binary fission is a type of asexual reproduction where a single-celled organism divides into two identical daughter cells. (correct)

Vegetative propagation is the production of new individuals from vegetative parts like roots, stems, leaves, and bulbs. (correct)

Spore formation is a type of asexual reproduction where new individuals are produced from specialized reproductive cells called spores. (correct)

Fragmentation is a type of asexual reproduction where new individuals arise from small pieces of the parent plant that break off. (correct)
