They store it for the night because, at night there is no sunlight
As the polysaccharide starch.
It is usually stored as a simple sugar known as glucose. When the food is created, the plant can either consume it right away or store it. If it consumes it, then it is starch.
Starch and cellulose.
photosynthesis
Plants store glucose for later use.

CARBOHYDRATES
In plants, carbohydrates are stored as starch. This is their main storage of energy, and it's all over the plants, helping it to continue to grow come springtime.
Cells store Extra Sugar as Larger Carbohydrates
Roots, stems, and leaves of plants primarily store extra carbohydrates, such as starch and sugars, which serve as energy reserves. Roots often store water and nutrients as well, helping the plant survive during unfavorable conditions. Additionally, stems can store additional nutrients and water, while leaves may store excess sugars produced during photosynthesis. These storage functions enable plants to maintain growth and vitality throughout various environmental changes.
Insects store carbohydrates as starch. Other animals and plants do the same thing since the starch can become different kinds of saccharides.
Yes.. Onions store carbohydrates as glucose(monosaccharide), fructose(monosaccharide), and sucrose(disaccharide), while potatoes store carbohydrates as starch(a polysaccharide chain of multiple glucose molecules).Hope this helps. :-)
