Which of the following statements correctly describes a difference between plant cells and animal cells? 2 points

A. Plant cells have an envelope surrounding the nucleus. Animal cells do not.

B. Animal cells contain mitochondria. Plant cells do not.

C. Animal cells contain chloroplasts. Plant cells do not.

D. Plant cells are surrounded by a cell wall. Animal cells are not.

D

Explanation:

plant cells are the only kind of cell to have cell 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.
