Question

ASAP What is a benefit of a plant having Chlorophyll and Carotenoids? A. The plant can absorb energy from multiple wavelengths at once. B. They can absorb both sunlight and moonlight . C. It is not a benefit. D. If one becomes damaged, the other can take over.

Answer

Chlorophyll a absorbs light from the blue and red parts of the visible spectrum, but not from the green. As green light is reflected, the chlorophyll appears green. Carotenoids, on the other hand, absorb blue light and reflect longer wavelengths like yellow, red, and orange. Chlorophyll, which is present in the chloroplasts of plants, absorbs red and blue light as shown in the absorption spectra. As green light is not absorbed but reflected, it makes the plant look green. Explanation: When light hits a plant, it is absorbed by pigments like chlorophyll and carotenoids that are present in the plant cells. Chlorophyll a, the primary pigment in plants, absorbs light energy through the process of photosynthesis. It absorbs light in the blue and red regions of the visible spectrum, but not in the green region, which is why it appears green. Carotenoids, a class of pigments found in plants, absorb blue light and reflect longer wavelengths like yellow, red, and orange. Absorption spectra show the wavelengths of light that are absorbed by a pigment, and in the case of chlorophyll, it absorbs light in the red and blue regions. This absorption of light provides energy for photosynthesis, which is the process by which plants convert light energy into chemical energy to fuel their growth and survival. Chlorophyll is found in the chloroplasts of plant cells, which are responsible for photosynthesis. As green light is not absorbed but reflected, the plant appears green.
