Q:Plant Pigments And Biology?
Pigments in the reaction center work together to organize themselves in place, to protect the plant from injury from incidental light, and to absorb photons from the spectrum with each pigment catching its own portion of the incoming wavelengths. The accessory pigments catch and pass energy to chlorophyll a. Chlorophyll a is the specialist that plays the photon's electromagnetic energy into chemical. It splits water to release its electrons and hydrogen ions for use in the calvin cycle where glucose is manufactured. The goal is to fix energy into a usable organic form for the plant to live on.
Q:Explain why plants need a variety of pigments to carry out photosynthesis?
flora must be conscious of distinctive wavelengths of light which each and each and each soak up terrific at a definite pigment. this would enable the main potential to be transfered to the plant with a vast spectrum of light.
Q:what is the difference between light color and pigment colors?
Check out the links below. They should answer any question about the properties of light. In a nutshell, the color of light is an electromagnetic radiation.that the human eye sees. The rainbow is a visual phenomenon that shows the transmission of those radiant colors. We see them,orange, yellow, green blue, indigo, violet at one time because they are being filtered through the moisture in the air. Of them all, only the primary colors are true, green and blue. The others are where the light blends together. Pigments are artificially produced things that bend light in such a way that we see a different color. A pigment reflects the available light, changes it because of its absorption property. Thats why black is both a color and the absence of color. In light, black is the combination of all colors (black absorbs all radiant light) and in pigment the absence of any color.
Q:thinking about the main role of pigments in photosynthesis...? explain how the pigments in colored objects suc?
photosynthetic pigment or antenna pigment is a pigment that is present in chloroplasts or photosynthetic bacteria and captures the light energy necessary for photosynthesis. Green plants have five closely-related photosynthetic pigments (in order of increasing polarity): Carotene - an orange pigment Xanthophyll - a yellow pigment Chlorophyll a - a blue-green pigment Chlorophyll b - a yellow-green pigment Phaeophytin a[1] - a gray-brown pigment Phaeophytin b[1] - a yellow-brown pigment Chlorophyll a is the most common of the six, present in every plant that performs photosynthesis. The reason that there are so many pigments is that each absorbs light more efficiently in a different part of the spectrum. Chlorophyll a absorbs well at a wavelength of about 400-450 nm and at 650-700 nm; chlorophyll b at 450-500 nm and at 600-650 nm. Xanthophyll absorbs well at 400-530 nm. However, none of the pigments absorbs well in the green-yellow region, which is responsible for the abundant green we see in nature.
Q:what are the types of pigments?
INORGANIC PIGMENTS Oxides Chromates Sulphides Sulphoselenides Sulphates Silicates Ferrocyandies Carbonates Metallic Mixed Metal Oxides Vanadates ORGANIC PIGMENTS Organic pigments are generally categorized into six types : •Monoazo Pigments •Diazo Pigments •Acid and base dye Pigments •Phthalocyanine Pigments •Quinacridone Pigments •Other polycyclic Pigments if you want more detail: ORGANIC PIGMENTS: 1.AZO Pigments : Monoazo Yellow and Orange Pigments. Disazo Pigments. β-Naphthol Pigments. Naphthol AS Pigments (Naphthol Reds). Azo Pigment Lakes (Salt Type Pigments). Benzimidazolone Pigments. Disazo Condensation Pigments. Metal Complex Pigments. 2.POLYCYCLIC Pigments: Phthalocyanine Pigments. Quinacridone Pigments. Perylene and Perinone Pigments. Diketopyrrolo–Pyrrole (DPP) Pigments. Thioindigo Pigments. Isoindolinone and Isoindoline Pigments. 3. Anthraquinone Pigments. Anthrapyrimidine Pigments. Flavanthrone Pigments. Pyranthrone Pigments. Anthanthrone Pigments. 4. Dioxazine Pigments. Triarylcarbonium Pigments. Quinophthalone Pigments
Q:do all leaves extract contain the same pigments??why?
Plants Plants have classes of pigments that act as adjuncts to the chloroplast's chlorophyll, in several ways. Some are accessory pigments that broaden the range of absorbed light. These pigments are found in the light gathering arrays in chloroplasts. They also alter the color of the leaf depending on what specific pigments it has to gather light energy and that determines what is reflected (green is the basic reflected spectra but is might be yellowish or bluish green). The major accessory class of pigments, the carotenoids, collect light in the red to yellow wavelengths chlorophyll a can’t, then the carotenoids transfer the energy to chlorophyll a to process. Among the carotenoids are the xanthophylls that provide UV protection for the light gathering centers of the chloroplast. Plants adapt to situations and some just have fewer chloroplasts so have less chlorophyll and absorb less of the light. In low light situations they need fewer so variegated plants are possible. This reduced chlorophyll level allows small amounts of other pigments like the yellow pigment xanthophyll to show up.
Q:What are MAC pigments?
Eyeshadow I think....
Q:Explain light activation of pigments (absorption of light by pigments)?
A pigment is a substance that imparts color by absorbing some frequencies of visible light but not others. For instance, there are a lot of substances that absorb ultraviolet light into the visible spectrum, in other words they also absorb plain violet light. Since they absorb violet light but reflect back the rest of light, they appear yellow. Purple pigments, on the other hand, are quite rare because they absorb purple light (which has the highest energy of visible light) and reflect back everything else. When anything absorbs a photon of electromagnetic radiation (light, x-rays, ultraviolet, infrared, microwaves, gamma rays, radio waves), it is activated which means that it takes the energy of the photon and goes to an energy state that is higher by the same amount of energy that was in the photon. At the molecular level, energy is quantized, meaning its restricted to particular states. For instance, vibrational energy corresponds to infrared light: there are only certain ways, called modes, that a molecule can vibrate in, if it can't vibrate in an appropriate mode, it can't absorb the infrared radiation that corresponds to being promoted to that mode. That's why substances can be transparent. At the higher energy state, the substance might be able to participate in chemical reactions that it would not be able to participate in in a lower state. That's usually what is meant by light activation. So a pigment that absorbs visible or UV light might become activated and react with something or react in ways that it wouldn't be able to in the dark.
Q:how are pigments classified?
What do you mean?
Q:Your classmate suggests that chlorophyll is not the only pigment contained in plant cells. Is your classmate c
There are carotinoids there too. The yellow, orange and red we see in leaves before they drop. Masked by chlorophyll until that production stops.
