How well would a plant grow under pure yellow light?

Most plants would not grow very well under yellow light, as this color is not easily absorbed by photosynthetic pigments in plants for use in photosynthesis. As a result of poor light absorption, the plant would probably die from a lack of nutrition.

Plants obtain their energy through the process of photosynthesis, during which light is absorbed and converted into energy. Green and yellow light is not absorbed by chlorophyll in plants and instead passes through them or is reflected, giving plants their color. The majority of light absorbed by plants is red and blue. All food and fossil fuels are absorbed through photosynthesis.
