Storage organ

A storage organ is a part of a plant specifically modified for storage of energy (generally in the form of carbohydrates) or water. [1] Storage organs often grow underground, where they are better protected from attack by herbivores. Plants that have an underground storage organ are called geophytes in the Raunkiær plant life-form

In chemical terms, photosynthesis is a light-energized oxidation–reduction process. (Oxidation refers to the removal of electrons from a molecule; reduction refers to the gain of electrons by a molecule.) In plant photosynthesis, the energy of light is used to drive the oxidation of water (H 2 O), producing oxygen gas (O 2

The success of photosynthesis as an energy-generating and -storage system stems from the fact that the raw materials and power needed for the synthesis of biomass are available in almost unlimited amounts; sunlight, water and CO 2. At the heart of the photosynthetic process is the splitting of water by sunlight into oxygen and hydrogen equivalents.

Copper treatment also resulted in a dramatic decrease of Rfd (vitality index), a moderate decrease in PES (energy storage) and a marginal decrease in F v′ F m′ values. High Cu concentrations inhibit O 2 evolution and the enhanced heat emission may be due to an inhibition of electron transfer and consequently of photochemistry.
