Which of the following is not a method of reproduction for aquatic flowering plants?

Fragmentation is a method of asexual reproduction commonly found in certain aquatic organisms, such as algae and some types of aquatic animals. However, it does not apply to aquatic flowering plants as a primary method of reproduction.

Aquatic flowering plants primarily reproduce through seeds, which allow for genetic diversity and colonization of new areas. They also reproduce through rhizomes, which are specialized underground stems that can give rise to new plants, enabling the species to spread vegetatively. Tubers serve a similar purpose by acting as storage organs that can give rise to new plants. Therefore, while fragmentation is a significant reproductive strategy in other aquatic organisms, it is not a recognized method for flowering plants. This distinction helps clarify the different mechanisms of reproduction in aquatic ecosystems.
