Q:Explain why plants need a variety of pigments to carry out photosynthesis?
In photosynthesis plants make their which is a carbohydrate i.e. a compound of carbon, hydrogen and oxygen. That carbohydrate is glucose (C6H12O6). The chemical equation of photosynthesis is : 6CO2 + 12H2O = C6H12O6 + 6O2 + 6H2O Here water, carbon dioxide and light (light gives the energy to prform the reaction) helps to form chains of carbohydrate that further makes sucrose, a type of sugar, which can be utilized by plants as food.
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.

Q:In photosynthesis whats the difference between primary and accesory pigments?
Primary pigments are molecules that convert light energy to chemical energy directly; chlorophyll is the primary pigment in all photosynthetic organisms. Accessory pigments are molecules that absorb photons which are not captured by chlorophyll. The presence of accessory pigments (found in the thylakoid membranes of plants) allows phototrophs (plants, algae, and cyanobacteria) to capture energy from the sun that would otherwise go to waste. The two most common types of accessory pigments are carotenoids and phycobilins. Some examples of carotenoids in common plants are: beta-carotein (carrot orange), lutein (marigold yellow), and lycopene (tomato red). Phycobilins are found only in red algae or cyanobacteria. The two most common phycobilins are: phycoerythrin (red), and phycocyanin (blue). The presence of accessory pigments in plants is masked by the presence of chlorophyll during the Spring and Summer seasons; that's why leaves are green most of the time. The color change from green to red, orange, or yellow that we observed during the Fall season is caused by the absence of chlorophyll; the accessory pigments are always present until the leaves fall as the trees go into dormant mode.
Q:which pigments are involved?
All photosynthetic organisms contain one or more organic pigments capable of absorbing visible radiation, which will initiate the photochemical reactions of photosynthesis. The three major classes of pigments found in plants and algae are the chlorophylls, the carotenoids and the phycobilins. Carotenoids and phycobilins are called accessory pigments since the quanta (packets of light) absorbed by these pigments can be transferred to chlorophyll. Chlorophylls chlorophyll a - present in all higher plants and algae chlorophyll b - present in all higher plants and green algae chlorophyll c - diatoms and brown algae chlorophyll d - red algae (chlorophyll a is present in all photosynthetic organisms that evolve O2.) Chlorophyll molecules contain a porphyrin 'head' and a phytol 'tail'. The polar (water-soluble) head is made up of a tetrapyrrole ring and a magnesium ion complexed with the nitrogen atoms of the ring. The phytol tail extends into the lipid layer of the thylakoid membrane. Carotenoids (carotenes and xanthophylls) Carotenes: -carotene - higher plants and most algae $-carotene - most plants some algae xanthophylls: luteol, fucoxanthol and violaxanthol Carotenoids contain a conjugated double bond system of the polyene type (C-C=C-C=C). Energy absorbed by carotenoids may be transferred to chlorophyll a for photosynthesis. Phycobilins (found mostly in red and blur-green algae): phycoerythrin phycocyanin allophycocyanin )
Q:how are the pigments in clothes differ from plant pigments?
Pigments are pigments. They are made of molecules that absorb some colors and reflect others from the visible spectrum of light, which gives everything color. Black pigments absorb everything and reflect nothing, so black is the absence of color and it is why dark clothing are warmer in winter. White pigments reflect everything and absorb nothing, so clothing that is white is cooler in summer. Most plants have more chlorophyll, a green pigment, in them than other pigments, so the plant is overwhelmingly reflecting green back to our eyes and absorbing the red and blue ends of the spectrum. In fall, when the chlorophyll breaks down, we can see the yellow, orange, and red pigments that are also in the leaf for a few weeks. In this way, all pigments are alike. However, perhaps what your teacher is looking for is that the green pigment chlorophyll in plants not only absorbs red and blue wavelengths of light, it also uses that energy to excite electrons from the molecules of chlorophyll and send them through an electron transport chain that enables light energy to be converted to chemical energy and store it in the C-H bonds of glucose, which is made during photosynthesis. Other pigments, whether they be in clothes or other objects such as cars or just about anything else do not do this. Only plant chlorophyll, or the green pigment in plants, converts light energy to chemical energy. That is the one huge difference. Otherwise, like all other pigments, chlorophyll absorbs some wavelengths of light and reflects others, in the case of chlorophyll, green wavelengths of light.
Photons are the packets of energy that light delivers. Different colors of light have different amounts of energy in each of the light's photons. So, green light's photons have different amounts of energy from red light's photons. Different materials absorb different amounts of energy via photons very selectively. It has to do with the energy states of the molecules, and the electrons that are in the outer shell.
Q:What pigments are used in photosynthesis?
Chlorophyll(green) is the primary pigment used in photosynthesis. Besides chlorophyll, plants also use pigments such as carotenes(orange) and xanthophylls(yellow).
Q:What are Candle Pigments or Candle Coloring Powders ? And What are Candle Liquid Dyes ?
Epona's answer is extremely sturdy. in case you seem up colour institutions you will locate diverse institutions reckoning on who has written them and what structures they're drawing from. yet you'll be able to desire to continually use institutions that make experience to you. case in point - you will in all probability locate that easy blue is the colour linked with peace. yet reckoning on what form of peace you're going for you may go with a diverse colour. possibly purple if that is for peace in the kin or with acquaintances, pink if that is religious in nature, or eco-friendly if that is physique appropriate. The institutions I genuinely tend to circulate with are: pink - lust, action, means, braveness Orange - creativity, braveness, means (extra innovative form than the pink). Yellow - issues bearing on the concepts (like possibly you have have been given a attempt to earnings for) or psychological suggestion. easy eco-friendly - prosperity darkish eco-friendly - therapeutic easy Blue - peace, tranquility darkish Blue - desires, on occasion suggestion pink - issues coping with the religious White - purification and can be a stand in for extremely just about something Black - liberating negativity, banishing purple - love, friendship, kin i do no longer think there is any colour that would desire to be prevented. yet I often use a diverse affiliation than what i've got listed. And my institutions are in user-friendly terms valid for yet somebody else in the event that they make experience to them. i exploit white candles maximum many times as I continually have them handy and that they might continually be spiced up with diverse oils this is something I do very often.
Q:What is the role of pigment in photosynthesis photosynthesis ?
Photosynthesis can't happen without the pigment chlorophyll (which is green and is why leaves and stuff are green). Chlorophyll is found in chloroplasts, an organelle in plant cells. Chlorophyll harnesses the sunlight's energy in order to split water (into hydrogen pairs and oxygen) so it can be used in the photosynthesis process (ie. in order to make glucose, the food source for plants). Hope this helps! :D
