So the plant has a store of energy when it can't gather enough glucose to support itself. Starch is insoluble so it can be stored within the plant easily and it can be converted back into glucose quite quickly using enzymes.
All cells must have energy to function. Glucose and other sugars are cell foodâthey are the power source for cell activities in almost all living things. When glucose is stored as glycogen or taken in as starch, it must be broken down into individual sugar molecules before cells are able to use it.Chemical energy is stored in the bonds of sugars. When a sugar molecule is broken down, a usable form of energy is released for the cell's life functions.Cells can release energy in two basic processes: cellular respiration and fermentation. Cellular respiration requires oxygen, but fermentation does not.ll cells must have energy to function.
