Answer 1

Hint: Sponges belong to phylum porifera, they produce gemmules and they have a tough coating. Yeast belong to fungi and they reproduce asexually by the process of budding. Tuber is a stem-like structure which is underground, it takes part in vegetative reproduction as in potato. Water hyacinth reproduces vegetatively by offsets.

Complete Step by Step Answer:
A Gemmule is a mass of asexually generated cells that has the potential to grow into a new organism or an adult freshwater sponge. They are tiny, bud-like cells that sponges create in order to resist harsh environmental conditions. Both sexual and asexual reproduction are possible in freshwater sponges. In yeast, blossoming typically happens when there is a plentiful supply of food. A little bud emerges from the parent body during this process of reproduction. Later, the parent yeast's nucleus splits into two pieces, and one of the pieces moves into the bud. Being stem tubers, potatoes eventually develop storage organs from their thicker stolons. The internodes and nodes on the tuber resemble those on a normal stem. The nodes are the eyes, each with a leaf scar.

So, option (C) is correct.





Note: Asexual reproduction, which prevents the recombination of genetic material, is a reproductive method (i.e. a form of apomixis). It uses unspecialized plant components that could develop into reproductive structures (e.g. roots, stems, or leaves).
