Do plants have cell walls and if so what are the cell walls made of

They do have cell walls, but animal cells don't. They are mostly made of cellulose.

Yes, and cell walls are primarily made out of Cellulose

Explanation:

Plant cell walls are primarily made of cellulose, which is the most abundant macromolecule on Earth.

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:

it cools slower in the earth meaning the crystals have more time to form than lava on the surface
