Tuber is a structure that provides nutrients for the next season regrowth. It is specialised for asexual reproduction. Potato is a stem tuber, for example. In one growing season, the tuber is produced and used to perennate the plant. In the autumn, when the plant structure above-ground dies, the tuber survives underground over the winter. When spring comes, tuber regenerates new shoots thanks to nutrients stored. On the other hand, true root crops (carrot, beetroot, radish) are modified roots to store energy but they are not specialised for asexual reproduction.
The correct answer for this question is D - lipids. Lipids are also
known as fat, and are useful not only as protection, but also as long
term storage for energy, protection for vital organs. A certain type of
lipid even assists with communication between cells.

Answer:
Option D, leaves
Explanation:
The maximum concentration of zinc is accumulated both in the leaves and stem of corn and tobacco plants. But comparatively it is higher in the leaves than in the stem.
Zinc is a micro nutrient as it is required only in a small amount and it is found that plants will lesser zinc concentration dry out easily.
Also the relation between the zinc absorbed is linear to the accumulation of zinc in the leaves. Hence, the higher the zinc absorbed in the corn and tobacco plants, the higher is the zinc accumulating in the leaves.
Hence, option D is correct
