Q:I have been looking over the internet and have yet to find the details I need. Such as the function and development of Pigments.: A pigment is essentially a substance that subtracts light to produce a variety of colors. In organisms, pigments are the colored matter (the substance in your cells that give your skin, tongue, hair, etc. their colors). In nonliving things such as painting, a pigment is the dry powder that is mixed with a fluid, creating a colored liquid which is then used to paint. As to how pigments work -- the pigment absorbs all light except the color you see. That color of light is reflected to your eyes. All kinds of substances can be pigments. I hope that was clear and answered your question!

Q:what is one reason why plants have accessory pigment molecules like chlorophyll b and carotenoids?: Chlorophyll actually speaking does'nt give the green color to the plant.It reflects the green wavelength and hence the green color.There are other pigments present in the leaf like chlorophyll a , chlorophyll b,c,d and e.Chlorophyll a is the primary pigment.It reflects the green,red and blue wavelength.It consitutes the reaction center in the chloroplasts which absorbs all the light incident on the leaf which in turn facilitates photosynthesis.Then there is Xanthophyll and carotene.Xanthophyll is orange yellow in color.Carotene is orange in color.Xanthophyll and Carotene are called as the accessory pigments present in the leaf.They reflect the blue, red and violet wavelength.I hope this info is sufficient.

Q:the absorption spectrum and the range of light reflected by each: three major pigments are 1.chlorophyll a 2.chlorophyll b 3.carotenoids chlorophyll a is the major pigment,chlorophyll b n carotenoid are the accessory pigments which help in absorption of the incident light of different wavelengths. another pigment xanthopyll-fucoxanthin is also present in some plants

Q:My wife went to the eye doctor to get new glasses (because she couldn't renew her driver's license with her glasses she had been using), and the doctor said that she wasquot;losing pigment&quot; in both of her eyes. He said not to worry, but he wants her to make an appointment every 6 months, instead of just once a year.What does it (her losing pigment in her eyes) mean? Is it really nothing to worry about?(My wife doesn't seem worried, she hates going to doctor's but she trusts them when she goes to them; she doesn't ask questions-- she feels that if she needed to know something the doctor would tell her.): Pigment is what gives your eyes color...meaning, if you have brown eyes, then you have pigment *if your eyes are blue, you lack pigment in your eyes*. It just means that color is disappearing from her eyes...have you noticed a slight color change? Keep an eye on it and her and see if anything else goes wrong. Best of luck to both of you.

Q:wut is the diff between those 2?: pigments are loose powder i believe. i like the eyeshadows better. there's a much better selection of those anyway.

Q:What is the role of pigment in photosynthesis photosynthesis ?: The pigment is known as chlrophyll, and plays a vital role in photosynthesis. It is a principal light-capturing pigment in most plants, algae and cyanobacteria. In plants and algae, chlorophyll is located in the thylakoid membranes of choroplasts. During the reaction of photosynthesis carbon dioxide and water produce energy using light energy trapped by the green pigment chlorophyll. This reactions primary products are ATP and NADPH, with oxygen being produced as a waste product. Photosynthesis takes place in the chloroplasts, where the green chlorophyll pigment is located.

Q:How can you extract pure pigments from a sample of leaves in a form that you could test the absorbency of the various pigments??I don't know how to extract enough pigment in order to fill a cuvette and measure the absorbance, please help!! :D: Separation of plant pigments using chromatography. Paper chromatography is a useful technique in the separation and identification of different plant pigments. In this technique, the mixture containing the pigments to be separated is first applied as a spot or a line to the paper about 1.5 cm from the bottom edge of the paper. The paper is then placed in a container with the tip of the paper touching the solvent. Solvent is absorbed by the chromatographic paper and moved up the paper by capillary action. As the solvent crosses the area containing plant pigment extract, the pigments dissolve in and move with the solvent. The solvent carries the dissolved pigments as it moves up the paper. The pigments are carried along at different rates because they are not equally soluble. Therefore, the less soluble pigments will move slower up the paper than the more soluble pigments. This is known as developing a chromatogram.

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.

Q:If you could explain it to me I would be very happy!: 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.
