Light Spectrum and Plant Growth
It is imperative to note that plants require light as an essential ingredient in the manufacturing of their food, and course growth and development. Moreover, botanists have established that the rate at which the chloroplasts absorb different wavelengths of light vary depending on the significance of the wavelength in the photosynthesis. In this regard, and view of the experiment, it is worth noting that the red light is the best light that stimulates plant growth. When a relative quantum efficiency curve on the rate of growth of plants under different light colors is drawn, then the red color will have the highest average. This reasoning is also supported by the experiment in which different plants are allowed to grow in restricted light wavelengths. The plants that are put in the red light will have extended growth leading to relatively taller plants as compared to those produced in other color bands.
Again from the experiment, it is imperative to note that when plants are subjected to different unitary wavelengths, then the plants growing under green light will be having the shortest growth. The reasoning is that the plant leaves reflect a lot of the green light; thus, very little proceed to the chloroplasts to facilitate the process of photosynthesis. .

The findings from the experiment reveal that the red color is the best for supporting plant growth since its absorption rate in the photoreceptor cells in the plant leaves is very high. The assertion resonates well with the revelation from the video since both espouse on the significance of the red light. Again both the revelations from the experiment and the insights from the video agree on the fact that merging blue and red has the best outcome for plant growth.
Since the red light is comprised of all colors, it would yield an optimal growth since the presence of all wavelengths in the white light would activate all photoreceptor cells in the chloroplast, thereby increasing the rate of photolysis.
