DENDROLOGY

Detailed explanation-1: -Chlorophyll absorbs certain wavelengths of light within the visible light spectrum. Chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Greenlight is not absorbed but reflected, making the plant appear green.

Detailed explanation-2: -Chlorophyll absorbs light most strongly in the blue portion of the electromagnetic spectrum, followed by the red portion. Conversely, it is a poor absorber of green and near-green portions of the spectrum, hence the green color of chlorophyll-containing tissues.

Detailed explanation-3: -For instance, plants appear green to us because they contain many chlorophyll a and b molecules, which reflect green light.

Detailed explanation-4: -Chlorophyll b absorbs mostly blue and yellow light. They both also absorb light of other wavelengths with less intensity. However, none of them absorbs green, so the leaf looks green because that light is reflected to our eyes instead of being absorbed by the leaf.
