Do all plants store starch?
Starch. When a plant produces glucose in excess, it can be converted into starch and stored, usually in the roots and seeds of the plant, where it is kept as a long-term energy reserve for the plant. Starches are found in seeds because they help feed plants in their embryonic stages, but are most often located in roots …
