For their own use, plants store energy as chemical energy in their biomass (stems, leaves, bark, and pulp) and in flowers (in the form of "nectar" -- sugars & other carbohydrates). Biomass allows the plant to grow, form a distinct structure, and to spread its leaves into a canopy to gather solar energy. Flowers are important to attract insects and birds for pollination, procreation, and genetic diversity.
Plants also store energy chemically, in their fruits and nuts. In fruits, this energy is stored (chemically) in the form of carbohydrates and simple sugars (in fruits), and as lipids/fats (in nuts and fatty fruits like avocados). These energies almost always surround the plant's seeds. Fruits and nuts form a pod, with its seeds inside, so they can fall or be carried away from the tree. This combination of seed pods (that can go away from the tree) and energy (surrounding its seeds) provide the initial nutrients (chemical energy) that its seeds (progeny/offspring) will need to take root and grow. This helps the plant to grow and expand as a species.
The shape of a plant can also store potential energy, in the form of very high branches and trunks. This is for the plant to reach heights, thus raising its own leaves over and above the other smaller bushes/trees, to let it capture more solar energy.
I think, YES, As the GROWTH and the FRUITS.
