Translocation of sucrose in plants occurs via specialized vessels which are: A. Thin hollow tubes of lignin. B. Abundant in mitochondria. C. Dead, narrow cells D. Contain sieve pores in their end walls. ​

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.

explanation:

the electromagnetic energy from the sun arrives in the form of visible and invisible light.
