Detailed explanation-1: -Carotenoids absorb light at wavelengths from 400 to 600 nm. This part of the spectrum is primarily blue and green. Carotenoids reflect light in the yellow, orange and red parts of the spectrum. That is why they appear yellow, orange, and red to us.

Detailed explanation-2: -Carotenoids: absorb light in the blue-green ranges and reflect the yellow, red and orange ranges. These pigments broaden the spectrum of colors that can drive photosynthesis.

Detailed explanation-3: -Carotenes. Pigments that belong to the carotenoids group. They give plants their yellow, orange, and red colours.

Detailed explanation-4: -Although chlorophyll only absorbs blue and orange light, other pigments in the leaves absorb the other colors. Some of those other pigments are called carotenoids. They absorb green light and reflect orange. Carrots have a lot of carotenoids.

Detailed explanation-5: -Carotenoids cannot transfer sunlight energy directly to the photosynthetic pathway, but must pass their absorbed energy to chlorophyll. For this reason, they are called accessory pigments.
