If a plant is kept under green colored light for an extended period of time, what willl happen to the plants food production

Plants food production will stop completely. Plant cells contains a pigment called chlorophyll in their chloroplast. They convert light into chemical potential energy. However, chlorophyll is green in colour. This is due to the pigment reflecting off only green light away, resulting I'm us viewing the plant as green coloured. This shows that green light could not be used during photosynthesis.

Plants in extended periods of green light would therefore experience no food production.

What is the question? if you were looking to design a method of separating something, you can separate this compound by putting both in water and allowing the water to dissolve the sugar. then pour it into another beaker and evaporate it then boom! salt and sugar : )
