Question

Plants reflect the colors of light that they do not absorb. This reflected light determines their color. Why are there few blue-colored plants?

Plants have lots of blue pigments.
Plants absorb blue light well.
Plants are not usually exposed to blue light.
Plants reflect most blue light.

Answer 1

The correct answer is "Plants absorb blue light well".

Step-by-step explanation:

"Chlorophyll A" is one of the most widely used biomolecules in plants, that serves the function of performing photosynthesis. "Chlorophyll A" absorbs light in the blue-violet region, and reflects light in the green-yellow region. The reflected light determines the color of plants, therefore, the properties of "Chlorophyll A" are the reason why most plants are green. In this sense, there are few blue-colored plants because plants absorb blue light well.

Answer 2

The answer is: Plants reflect most blue light.

Plant color depends on the color of light they reflect and not on the color they absorb. For example, a green plant is green because its pigment chlorophyll absorbs red and blue light, and reflects green light. So, if some plant is blue-colored, that suggests that it reflects blue light.
