Chlorophyll b pigments readily absorb light in the blue and red regions of the electromagnetic spectrum. Specifically, they absorb light most efficiently in the blue wavelengths around 450-500 nm and in the red wavelengths around 640-680 nm. These absorbed wavelengths of light drive the process of photosynthesis by exciting electrons in the pigment molecules.
What else can I help you with?
True or false Chlorophyll pigments absorb mostly green wavelenghts and reflect blue and red wavelenghs?
True. Chlorophyll pigments primarily absorb blue and red wavelengths of light and reflect green wavelengths, giving leaves their green color.
What compounds do many algae have to help them absorb light at different wavelenghts?
Many algae contain pigments such as chlorophyll a, chlorophyll b, carotenoids, and phycobilins to absorb light at different wavelengths. These compounds allow algae to capture light energy for photosynthesis efficiently across a broad spectrum of light wavelengths in the aquatic environment.
In a photosystem clusters of chlorophyll a chlorophyllb and carotenoid pigments function most like what?
Clusters of chlorophyll a, chlorophyll b, and carotenoid pigments in a photosystem function most similarly to antenna complexes in capturing and transferring light energy. These pigments absorb light at different wavelengths and transfer the energy to the reaction center chlorophyll to drive the photosynthetic process.
Which substance is a green pigment in chloroplasts that absorbs energy for photo system?
Chlorophyll
What produces color in flowers?
Color in flowers is produced by pigments called anthocyanins, carotenoids, and chlorophyll. These pigments absorb certain wavelengths of light and reflect others, giving the flowers their unique color. The presence and combination of these pigments determine the specific color of a flower.
True or false Chlorophyll pigments absorb mostly green wavelenghts and reflect blue and red wavelenghs?
True. Chlorophyll pigments primarily absorb blue and red wavelengths of light and reflect green wavelengths, giving leaves their green color.
How do accessory pigments differ from chlorophyll a?
Accessory Pigments absorb energy that chlorophyll a does not absorb.
What are the substances in placids that absorb various wavelengths of light?
Placids typically contain pigments like chlorophyll a, chlorophyll b, and carotenoids that absorb various wavelengths of light for photosynthesis. These pigments help capture light energy and convert it into chemical energy for plant growth and development.
Why does a leaf appear green when a person looks at it?
The chlorophyll pigments absorb all wavelengths of light except in the green spectrum, which it reflects.
What are four examples of plant pigments?
orange carotenes and yellow xanthophylls, absorb different wavelengths of light and pass that energy on to chlorophyll molecules. The carotenoids are pigments, including carotenes
Figure 10.1 shows the absorption spectrum for chlorophyll a and the action spectrum for photosynthesis Why are they different?
The absorption spectrum shows which wave lengths are absorbed in each individual type of chlorophyll. The action spectrum shows which wavelengths of light are most effective for photosynthesis.
What compounds do many algae have to help them absorb light at different wavelenghts?
Many algae contain pigments such as chlorophyll a, chlorophyll b, carotenoids, and phycobilins to absorb light at different wavelengths. These compounds allow algae to capture light energy for photosynthesis efficiently across a broad spectrum of light wavelengths in the aquatic environment.

Which substance is a green pigment in chloroplasts that absorbs energy for photo system?
Chlorophyll
Chlorophyll a and b are associated with what?
Chlorophyll a and b are pigments found in the chloroplasts of plant cells responsible for capturing light energy during photosynthesis. They absorb light of different wavelengths, allowing plants to maximize their energy absorption from the sun.
What produces color in flowers?
Color in flowers is produced by pigments called anthocyanins, carotenoids, and chlorophyll. These pigments absorb certain wavelengths of light and reflect others, giving the flowers their unique color. The presence and combination of these pigments determine the specific color of a flower.
How do accessory pigments differ in function from chlorophyll and how do they affect the appearance of algae and the depths at which algae can grow?
Accessory pigments absorb light at different wavelengths than does chlorophyll. This process tends to increase the range of depths at which algae can grow. For example, the reddish accessory pigments called phycobilins are especially good at absorbing the blue light found at great depths in the sea, allowing the algae that contain them to live in deep water. Because accessory pigments reflect different wavelengths of light than does chlorophyll, they give algae a wide range of colors.
