Storage form the glucose used by plant cell?
Some plants can store their extra glucose supplies as starch in special parts in the roots called tubors for use during winter when they are not able to photosythesise.
Chloroplasts are plant cell organelles that both capture light energy and then use that energy to chain carbon atoms together with hydrogen and oxygen to form carbohydrates in the form of the simple sugar glucose or polymers of glucose (starches) which serve as energy storage medium in the plant for later use.
Plant Cells use glucose sugar and cellulose while animal Cells use mostly [glucose derived] glycogen. 1) be broken down by the mitochondria to supply energy to the cell. 2) be linked together in long chains to form cellulose and build the plant cell wall. 3) be moved to another part of the plant for energy, or moved to the root system for storage (in the form of starch).
