Hint: There are different modes of reproductions namely sexual reproduction and asexual reproduction. Sexual reproduction involves the fusion of gametes from two different individuals, whereas, asexual reproduction involves a single parent to give rise to a new offspring.
Complete answer: Asexual reproduction is observed in both multicellular and unicellular organisms. Asexual reproduction involves a single parent without the fertilization or formation of gametes. The offspring produced are genetically as well as physically identical to each other and hence are termed as clones.
There are different modes of asexual reproduction are as follows:
1. Fission is the division of the parent cell into two or more cells. Binary fission and multiple fission are the two types of fission. Binary fission is exhibited by organisms such as the bacteria, Amoeba, Euglena,, etc., whereas, multiple fission is exhibited by organisms such as algae and sporozoans.
2. Budding is the process of development of buds on the organism’s body. The bud arising from the parent organism matures into a new organism of the same kind and detaches itself from the parent organism’s body. Hydra is one such example of an organism that exhibits budding as a mode of reproduction.
3. Spore formation is another mode of asexual reproduction, wherein organisms like fungi, fern, etc. produce spores in a sporangium, which is a sac-like structure. The sporangium under favorable conditions, burst to release the spores. These spores mature and germinate to form new offspring.
Thus, budding (e.g. Hydra), binary fission (e.g. Amoeba, bacteria), vegetative propagation (e.g. Onion), fragmentation (e.g. Planaria<./i>), and spore formation (e.g. ferns).
Therefore, the correct answer is option D-All of the above.
Note: Other modes of asexual reproduction include vegetative propagation and fragmentation. Fragmentation involves the multicellular organism to break down into segments, wherein each segment germinates to form a new organism. And vegetative propagation occurs in the leaves, stems, and roots of a plant. Specific vegetative parts undergo regeneration and fragmentation in this type of asexual reproduction.
