Answer:
Blue light helps with lettuce cultivation because it resembles natural light, so it allows the lettuce to photosynthesize what is necessary for its development.
Pigments only absorb light. This is true
Step-by-step explanation:
The plant develops and grows through photosynthesis. Light is essential in the biochemical process for plant growth, and blue and red radiation are bands in the light spectrum that are the main ones the plant uses for photosynthesis. In addition, artificial blue light resembles natural light. Thus, we can say that in lettuce cultivation, the blue light allows the lettuce photosynthesize enough for its development.
Pigments are chemical compounds that give color to plants. Their main function is to capture the radiation needed for plant metabolism.
