Sugar,
sugar helps increase cellulose and help the plant grow faster. Plain water will maintain the status Que.
I think that sugar water will freeze faster.
Test it yourself
plain water freezes faster . ps: try freezing dirty water and plain water together , it's fun!
Pure water freeze faster.
I did an experiment with Dwarf sunflowers using tap water, rain water, distilled water, vinegar water, salt water, and sugar water. In this experiment the only 3 waters that did not grow the plants were vinegar, salt, ans sugar waters. I'm not certain these results will be correct every time but it is possible that plants grow better with regular water instead of sugar.

This is the plain water.
sugar water
For salt water to boil faster than plain water, the salt concentration would have to be fairly high. In addition, the salt water would need to be a salt water solution before putting the pot on to heat because of the density of the water content itself.

Plain Water. Sugar water causes a aciding effect on the plant and will form a white mold.
depends
boiled water
No, addition of table salt (NaCl) to water used for watering plants will normally kill the plant.
Probably slower, since it has less concentration of water.
simply becuase the density of the water is increased..
Plain water evaporate faster.
