Are Red orange and yellow pigments only present in a plant when photosynthesis stops?
No, red, orange, and yellow pigments can be present in plants even during photosynthesis. These pigments, such as carotenoids and anthocyanins, play important roles in capturing light energy and protecting the plant from damage caused by excess light. Additionally, they contribute to plant coloration, serving functions beyond photosynthesis.
What plant pigments are found in plants other than the green pigments?
Aside from green chlorophyll pigments, plants may contain other pigments such as carotenoids (usually yellow, orange, or red), anthocyanins (usually purple, blue, or red), and betalains (usually red or yellow). These pigments help in photosynthesis and contribute to the plant's overall coloration and protection against environmental stress.
What are pigments that absorb other wavelengths and appear yellow and orange called?
Carotenoid pigments are responsible for giving yellow and orange colors to plants by absorbing light in the blue and green wavelengths and reflecting yellow and orange light.
What pigment causes the yellow color of leaves in autumn?
Carotenoids are the pigments responsible for the yellow color of leaves in autumn. These pigments are present in the chloroplasts of plant cells and help in the process of photosynthesis. As the green chlorophyll pigment breaks down in the fall, the carotenoids are revealed, resulting in the yellow hues in leaves.
What color leaf pigment do you get with carotenoid?
Carotenoids produce yellow, orange, and red leaf pigments, depending on the specific type and concentration present in the plant.
