Canadian winters can be particularly harsh. describe two adaptations of stems that plants survive canadian winters.

Plant species have had to adapt to freezing and the presence of ice in many climatic zones.

Explanation:

Cold environments are an important ecosystem with distinct characteristics and adaptations. They provide opportunities for development, but are put at risk by the exploitation of resources. In order for plants to survive in cold environments they have had to adapt to the extreme conditions found there. These plants  produce storage organs below ground, to survive in the cold climate.

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.
