Answer :
Final answer:
Potato tubers form on the tips of stolons and involve the shoot system and vascular tissue for their development and storage of carbohydrates; thus, option D is correct.
Explanation:
In the context of plant biology, tubers are specialized structures involved in the storage of carbohydrates. In the specific case of the potato (Solanum tuberosum), these tubers are formed on the tips of stolons, which are part of the shoot system. A potato tuber is essentially a swollen stem that has nodes, also known as "eyes," that can develop into new potato plants if the conditions are right. The formation of tubers involves the shoot system, particularly the stolons, and the vascular tissue, which transports nutrients necessary for the tuber's growth and the storage of carbohydrates. Therefore, the correct answer to the question is option D, which states that the shoot system, root system, and vascular tissue are the plant structures most involved in the formation of tubers.
