Why are carotenoids coloured?
Carotenoids have conjugated bonds. Wavelengths of visible light are absorbed when electrons are excited to higher energy levels. The complementary colour is to that absorbed is observed.
Do carotenoids cause plants to positively respond to sunlight?
Yes, carotenoids play a role in photosynthesis by absorbing light energy, which can help plants respond positively to sunlight. Carotenoids protect plants from excess light by dissipating the energy as heat, reducing the potential for damage from high light intensity.
What are the three general groups of plant pigments?
The three types of pigments found in a plant are chlorophyll a, chlorophyll b, and carotenoids (mainly carotene). Chlorophyll a (the main pigment) absorbs blue-green light, chlorophyll b absorbs yellow-green light, and carotene absorbs yellow-orange light.
What is the adaptive value of a accessory pigments like carotenoids?
Accessory pigments like carotenoids play a role in photosynthesis by capturing light energy and transferring it to chlorophyll molecules. They also help protect the plant from damage caused by excess light or reactive oxygen species. Overall, carotenoids provide an adaptive advantage by enhancing photosynthetic efficiency and offering protection against environmental stressors.
Where are chlorophyll a chlorophyll b and the carotenoids are located?
Chlorophyll a, chlorophyll b, and carotenoids are located in the thylakoid membranes of chloroplasts. They are essential pigments used in the process of photosynthesis to capture light energy and convert it into chemical energy.
Absorbs wavelengths of light different from those absorbed by chlorophyll?
carotenoids :]
What are xanthophyll?
These are carotenoids
What is the molecular formula for carotenoids?
The molecular formula for carotenoids is C40H56, which represents a group of naturally occurring pigments that give many fruits and vegetables their characteristic colors, ranging from yellow to red. Carotenoids serve as antioxidants and are important for plant photosynthesis.
Do carotenoids contain starch?
No, carotenoids do not contain starch. Carotenoids are a group of pigments found in plants that give fruits and vegetables their vibrant colors, while starch is a complex carbohydrate found in plants that serves as a storage form of energy.

Does animals obtain carotenoids in their diets?
yes
What side effects can carotenoids cause?
A person taking high doses of beta-carotene and other carotenoids may develop a yellowish color on his feet and hands.
Why are carotenoids coloured?
Carotenoids have conjugated bonds. Wavelengths of visible light are absorbed when electrons are excited to higher energy levels. The complementary colour is to that absorbed is observed.
What color would a flamingo be if it did not ingest carotenoids?
WHITE!
