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.
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.
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.
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.
Both "brightly-coloured" and "brightly coloured" are correct in British English, with the former being more typical. In American English, "brightly colored" without a hyphen is commonly used.
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.

These are 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.
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.

carotenoids
Flowers get their color from pigments such as anthocyanins and carotenoids. Some naturally evolved to have colors. Others were hyridized by humans to have colors different than the original parent plants.

yes
A person taking high doses of beta-carotene and other carotenoids may develop a yellowish color on his feet and hands.
