Do plants grow better in light or dark experiment and effect does darkness have on plant growth?
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 to power their growth. The plants that were not exposed to light grew 15.7 millimeters more on average, and the difference of growth between no light and half light plants were 7.27 millimeters. In conclusion, the plants that were exposed to no light whatsoever, were the ones who grew significantly larger than the other plants. That means that plants need light to grow and survive. As such, a plant grown in complete darkness will not produce enough energy or food. And without it, eventually, the cells die because they do not get enough nutrients. Ultimately, plants grown in the dark will grow up to be stunted and underdeveloped

The seeds in the dark-grown condition rely upon the stored chemical energy within their cells to power their growth. In plants that were exposed to no light whatsoever, were the ones who grew significantly larger than the other plants.The plants that were grown under the blue light had a steadier growth rate compared to the plants grown in the green light but again the growth fizzled towards the end. The plants grown under the red light had a very steady growth rate as each red plant grew about 2 cm every other day throughout the two week period. As such, a plant grown in complete darkness will not produce enough energy or food and without it, eventually, the cells die because they do not get enough nutrients. Ultimately, plants grown in the dark will grow up to be stunted and underdeveloped. Plants may grow taller in a dark place for a while: They respond to the lack of light by growing "taller" and more spindly, and the plant stem and leaves may be yellow and not as leafy. The growth in the dark is caused by auxins, which are substances that regulate plant growth.
