In photosynthesis, redox reactions ultimately transfer electrons from ______ to ______.
german

The correct answer is: D) H2O… CO2

Redox reactions are reactions of reduction (molecules tend to gain electrons) and oxidation (molecules tend to lose electrons).

Photosynthesis is a set of redox reactions. In photosynthesis electrons are removed from water (H2O) to carbon dioxide CO2 and then used to turn CO2 into organic compounds.  

The first step: Oxygen in water is oxidized (light energy required)

The second step: Carbon in CO2 is reduced; sugar is formed (dark reaction).

On the other side, vascular plants have vascular tissue which consists of xylem and phloem. Xylem transport water and minerals from the root to the upper parts of the plant. Phloem transports food and nutrients from the leaves, where they are produced, to the growing or storage parts of the plants.
