Over 80% of the calories consumed by humans come from starch, a carbohydrate produced and stored by plants. While photosynthesis occurs in leaves, plants must transport and store this energy throughout their structure, including the stem. The answer to "Does stem contain starch?" is a resounding yes, though the amount and specific location vary greatly between species.

Plants are incredibly efficient at managing their energy, producing more carbohydrates than they can immediately use during peak photosynthesis. To prevent osmotic stress and ensure a steady supply of fuel, plants convert this surplus glucose into a compact, insoluble polysaccharide called starch. This stored energy reserve is then strategically utilized to power the plant's metabolic processes during periods of darkness or reduced light.
