What Part Of Plant Can Store Extra Food As Sugar Or Starch?

Healthy plants tend to create much more food than they can immediately use. The excess food is stored as sugars and starches in various parts of the plants. These stores provide a source of energy not only for the plants, but also for the animals and humans that eat them. Plant Foods Carbohydrates are the simplest types of foods manufactured and stored by plants. Sugar and starch are two types of carbohydrates. Plant food is made in the leaves, where the green compound chlorophyll absorbs energy from the sun in a process called photosynthesis. Glucose Glucose is a simple sugar that is stored in large quantities in the stems of some plants. One example is the thick stems of the corn plant. Fructose Fructose is another simple sugar. Its chemical composition is slightly different from that of glucose and usually is stored in fruit. For this reason, it commonly is called fruit sugar. Complex Sugars Some plants, such as sugar cane and sugar beets, are very efficient at creating and storing complex sugars. These plants take the simple sugars, glucose and fructose, and create a higher form of sugar that is stored in either the stems, such as in the cane, or the roots, as in the sugar beet Continue reading >>

    1. The problem statement, all variables and given/known data
    Why does the human body spend two high energy phosphate bonds to store glucose as glycogen in muscle and liver, and not just as glucose? What is the advantage in using energy to polymerize the glucose molecule?
    2. Relevant equations
    3. The attempt at a solution
    Why is glucose stored as glycogen in muscle and liver, and not just as glucose?
    Below are some theories I proposed please correct me if I am wrong.
    Glycogen is insoluble thus, storing it as glycogen will not upset the osmotic pressure rather than glucose which is soluble in water and if it is stored as glucose it will disturb the osmotic pressure(hypertonic) that will cause the cell to lyse.
    Glycogen is a polymerized form of sugar with alpha 1,4 and alpha 1,6 that enables that can be degraded efficiently rather than free floating glucose. with that in mind wouldn't it be as efficient if glucose is stored in the liver and shipped to the desired destination if it is possible to store it in the cell without disturbing the osmotic pressure?
    Glucose is unstable and forms a ring which maturate with a predominance of beta anomers which is favored structure but also, the cell would have a alpha glucose that is unable to undergo glycolysis and it wouldn't be accessible when it is needed for breakdown.

Unstable is a relative term but Glucose is pretty damn stable. You can store glucose for years on your shelf without any degradation.
