Difference Between Plants Grown in Light and Dark
The light slows stem elongation through hormones that are sent down the stem from the tip of the stem. In the darkness, the hormones do not slow stem elongation. The seeds in the dark-grown condition rely upon the stored chemical energy within their cells (lipids, proteins, carbohydrates) to power their growth.
Do plants grow better in light or dark experiment?ANSWER: In a strict sense, plants do not grow faster in the dark; they grow slower.
