According to botanists, a surprising number of plants produce seeds that are either toxic, physically harmful, or indigestible, classifying them as non-edible. This broad category of seeds, which are unsafe for human or animal consumption, holds a variety of hidden dangers and valuable industrial applications that often go unnoticed. Understanding what are non-edible seeds is crucial for both safety and appreciating their unexpected utility.

Research shows that untreated corn husks are typically composed of approximately 29–45% cellulose, 34–45% hemicellulose, and 2–14% lignin. These figures reveal what are the chemicals in corn husks, highlighting their makeup as a complex, natural, lignocellulosic biomass rather than a simple compound.

As the most abundant biopolymer on Earth, cellulose accounts for over half of all biomass, offering a significant renewable resource. The answer to "can cellulose be converted into sugar?" is a definitive yes, through processes that break down this complex carbohydrate into simple glucose molecules for use in sustainable fuels and chemicals.

The sun delivers more energy to Earth in one hour than humanity consumes in a year, making solar power an immensely abundant source. However, the definition of a "rich" source of energy depends on the context, considering factors like density, abundance, cost, and impact.
