- Q:why do plants need more than one pigment for light absorption?
- Pigments are molecules with an array of covalent bonds capable of absorbing a photon of light that has only a certain wavelength. The absorbed wavelength is only a fraction of the continuous range of wavelengths reaching the reaction center of a chloroplast. Each pigment species absorbs a different portion of the spectrum. So most photosynthesis works in combinations of pigments to absorb a across the visible spectrum and somewhat beyond. Some pigments (accessory photosynthesis carotenoid pigments) absorb useful wavelengths to pass the energy to chlorophyll A while the Xanthophyll Cycle pigments absorb potentially harmful high energy wavelengths for dissipation. Accessory pigments provide a range of spectra collection that allowed plants to adapt successfully to environments of differing light conditions. Pigments provide coloration to signal flower or fruit maturity to pollination partners or seed dispersal partners. Anthocyanins and carotenoids perform these communication functions. Phytochrome is a pigment that absorbs one wavelength only to toggle to another shape capable of absorbing at a different wavelength. Algae and plants both use this system to inform them of the time of year so they can synchronize with the best season in their habitat for reproduction efforts to succeed. Plants use phytochrome to regulate the photoperiod of flowering or seed germination.

And regarding how they are produced, well each one has it´s own methods. You may want to search each of those names and you can find information for each one. Hope this helps, Bella
- Q:what is pigment eyeshadow?
- All these people are looking for a way through which they can make their skin look good. Yet, what they have not taken into consideration is the power of natural ingredients. Fruits, vegetables and products coming from animals are great sources of anti-oxidants and are rich in substances which can whiten the skin, moisturize it, attenuate the fine lines and wrinkles and give it elasticity.
- Q:what are the accessory pigments in plant photosynthesis?
- The photosynthetic pigments are of two types, primary pigments and accessory pigments. The accessory pigments pass the emitted electrons to the primary pigments. Electrons are then emitted from the primary pigments and it is these that drive the photosynthetic process. The two primary pigments are both forms of chlorophyll a, called P690 and P700 (absorbing light best at 690 and 700 nm wavelengths, respectively). The accessory pigments include other forms of chlorophyll a, chlorophyll b and carotenoids. The light energy trapping systems of the plant are called photosystem I and photosystem II. Energy capture traps of photosystems I and II (in the quantosomes) light energy The quantosomes are regularly spaced particles embedded in the thylakoids, and are either large or small. It is probable that the large quantosomes contain photosystem II and reaction centre II and the small quantosomes contain photosystem I and reaction centre I.
- Q:What are the accessory pigments and what are their functions?
- Accessory pigments are light-absorbing compounds, found in photosynthetic organisms, that work in conjuction with chlorophyll a. They include other forms of this pigment, such as chlorophyll b in green algal and higher plant antennae, while other algae may contain chlorophyll c or d. In addition, there are many non-chlorophyll accessory pigments, such as carotenoids or phycobiliproteins which also absorb light and transfer that light energy to photosystem chlorophylls. Some of these accessory pigments, particularly the carotenoids, also serve to absorb and dissipate excess light energy, or work as antioxidants.
- Q:what is the relationship between chlorophyll a, accessory pigment?
- Chlorophyll is the pigment that allows plants—including algae—to convert sunlight into organic compounds in the process of photosynthesis. Chlorophyll a is the predominant type found in algae and cyanobacteria (blue-green algae), and its abundance is a good indicator of the amount of algae present in the waters of the Chesapeake Bay. Excessive quantities of chlorophyll a can indicate the presence of algae blooms. These usually consist of a single species of algae, typically a species undesirable for fish and other predators to consume. Unconsumed algae sink to the bottom and decay, using up the oxygen required by other plants and benthic organisms to survive. The presence of too many nutrients, such as nitrogen and phosphorus, can stimulate algal blooms and result in reduced water clarity. Chlorophyll a also plays a direct role in reducing the amount of light avalable to plants in shallow-water habitats. This directly impacts the ability of underwater bay grasses to thrive. Like their terretrial cousins, grasses need sunlight to grow. As chlorophyll a levels increase, the amount of sunlight reaching underwater grasses declines. Chlorophyll a is the main pigment, chlorophyll b and carotenoids are accessory pigments. accessory pigments help broaden the absorbtion spectrum, as chlorophyll a absorbs violet-blue and red light. with the addition of accessory pigments chlorophyll b and carotenoids, yellow-green (chlor b) and violet and blue-green light (caro)
- Q:advantages of having accessory pigments?
- Each photon has a particular wavelength, determined by the photon's energy. A pigment such as chlorophyll can only absorb photons in particular wavelength bands, matching the energies of available electron transitions to excited states. For chlorophyll, these bands are in blue and red -- the green color of most leaves is due to the waste light that is not absorbed by chlorophyll, while red and blue photons can be absorbed and used to power photosynthesis. An accessory pigment can absorb a photon that has a wavelength (color) outside of the bands that chlorophyll is able to absorb and can pass some of the absorbed energy on to chlorophyll, getting rid of the excess energy in another form, such as heat. A pigment might be tuned to absorb a photon of yellow light; the absorbed energy, stored in the excited state of an electron, is called an exciton (the photon becomes an exciton, so energy is not created or destroyed). The exciton can be passed to a chlorophyll, but only with the same energy as the red photon that the chlorophyll could normally absorb directly. The excess energy, the difference in energy between the yellow and red photon, must be dissipated in another form. This process allows a plant to harvest photons that would otherwise be unavailable to its photosystems. Consider how this would be an advantage to a plant living on a shaded forest floor, or to a planktonic cyanobacteria floating in the water below other photosynthetic algae, in regions where photosynthetically useful photons are scarce.
- Q:what is pigment?
- a pigment has some kinds like biological pigment and arsenic pigment. i dont know much about the arsenic pigment. i would just tell something about the biological pigment. in biology, pigment is any material resulting in color of plants or animals cells. many biological structures like eyes,fur,hair and skin contains pigments like melanin in specialized cells called chromatophores.
- Q:why light and pigments are different?
- A pigment is a material that changes the color of reflected or transmitted light as the result of wavelength-selective absorption. This physical process differs from fluorescence, phosphorescence, and other forms of luminescence, in which a material emits light. Many materials selectively absorb certain wavelengths of light. Materials that humans have chosen and developed for use as pigments usually have special properties that make them ideal for coloring other materials. A pigment must have a high tinting strength relative to the materials it colors. It must be stable in solid form at ambient temperatures. For industrial applications, as well as in the arts, permanence and stability are desirable properties. Pigments that are not permanent are called fugitive. Fugitive pigments fade over time, or with exposure to light, while some eventually blacken. Pigments are used for coloring paint, ink, plastic, fabric, cosmetics, food and other materials. Most pigments used in manufacturing and the visual arts are dry colourants, usually ground into a fine powder. This powder is added to a vehicle (or binder), a relatively neutral or colorless material that suspends the pigment and gives the paint its adhesion.
- Q:What is the difference between a pigmented eyeshadow and a non - pigmented one?
- A pigmented eyeshadow means that it comes out on your eyes the color it is in the tray or palette for example you buy a black eyeshadow and when you swatch it or apply it to your eyes it looks dark gray or just completely different from how it appears to be
