Q: do all leaves extract contain the same pigments??why?
Absolutely not. Leaf pigments, just to name a few, may include chlorophyll, carotenes, lutein, anthocyanins. Not only will pigment content vary between plant species, but pigment content will vary in individual plants seasonally.
Q: What are MAC eyeshadow pigments? Are they just like regular eyeshadow.. are they used the same way? Has anyone tried them and liked them?
there just loose eyeshadows, yes they are like regular eyeshadow, i like them but they can be messy
Q: Please and thank you, it doesn't say so on the website.
Mac Pigment Ingredients
Q: like what's the definition relating to sunlight
Pigments are substances which are used familiarly to create pictures and printings. Pigments give an object a color when in a field of incident white light. Pigments themselves absorb a set of incident colors of light and reflect all others. When multiple pigments are mixed, their ability to absorb colors is added, such that their ability to reflect colors is subtracted.
Q: Does anyone know its chemical formula or constituents ?
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 are accessory pigments?
Accessory pigments are light-absorbing compounds, found in photosynthetic organisms, that work in conjunction with chlorophyll a. They include other forms of this pigment, such as chlorophyll b in green algal and higher plant , 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 chlorophyll. Some of these accessory pigments, particularly the carotenoids, also serve to absorb and dissipate excess light energy, or work as antioxidants. The different chlorophyll and non-chlorophyll pigments associated with the photosystems all have different absorption spectra, either because the spectra of the different chlorophyll pigments are modified by their local protein environment, or because the accessory pigments have intrinsic structural differences. The result is that, in vivo a composite absorption spectrum of all these pigments is broadened and flattened such that a wider range of visible and infrared radiation is absorbed by plants and algae. Most photosynthetic organisms do not absorb green light well, thus most remaining light under leaf canopies in forests or under water with abundant plankton is green, a spectral effect called the green window. Organisms such as some cyanobacteria and red algae contain accessory phycobiliproteins that absorb green light reaching these habitats.

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: what is the function of pigment molecules in photosynthesis?

Q: What happens to the yellow pigments in a leaf during the summer months?
in case you may surely ask a query like that, then it sounds to me such as you opt to have intercourse with one in all your instructors. enable me be the 1st to tell you that it will no longer take place! She's/he's have been given a husband/spouse to do each and all the grimy paintings for her/him! you're basically a pupil and that's a criminal offense in each and each state for a instructor to have something for a minor! Have had a weigh down on a instructor, definite that's a load of bull-****, yet that's the way life is and we the two might desire to provide up dreaming and locate ourselves a hoe which will please us in each way conceivable! that's effective to appreciate that somebody else has wandered that. % me as suited answer on account which you and that i've got lots in worry-loose!
