- Q:Which of these is NOT a major photosynthetic pigment in plants?
- Chlorophylls are greenish pigments which contain a porphyrin ring. This is a stable ring-shaped molecule around which electrons are free to migrate. Because the electrons move freely, the ring has the potential to gain or lose electrons easily, and thus the potential to provide energized electrons to other molecules. This is the fundamental process by which chlorophyll captures the energy of sunlight. There are several kinds of chlorophyll, the most important being chlorophyll a. This is the molecule which makes photosynthesis possible, by passing its energized electrons on to molecules which will manufacture sugars. All plants, algae, and cyanobacteria which photosynthesize contain chlorophyll a. A second kind of chlorophyll is chlorophyll b, which occurs only in green algae and in the plants. A third form of chlorophyll which is common is (not surprisingly) called chlorophyll c, and is found only in the photosynthetic members of the Chromista as well as the dinoflagellates. The differences between the chlorophylls of these major groups was one of the first clues that they were not as closely related as previously thought. Carotenoids are usually red, orange, or yellow pigments, and include the familiar compound carotene, which gives carrots their color. These compounds are composed of two small six-carbon rings connected by a chain of carbon atoms. As a result, they do not dissolve in water, and must be attached to membranes within the cell. Carotenoids cannot transfer sunlight energy directly to the photosynthetic pathway, but must pass their absorbed energy to chlorophyll. For this reason, they are called accessory pigments. One very visible accessory pigment is fucoxanthin the brown pigment which colors kelps and other brown algae as well as the diatoms. From this I would say the answer is c.
- Q:What are the ingredients in MAC's pigments? (10pts)?
- Mac Pigment Ingredients
- Q:What are iridescent magnetic effect pigments?
- Iridescent okorder.com/... (really long explanation)
- Q:What is a pigment and their function in photosynthesis?
- Chlorophyll. These pigments convert sunlight into glucose and some more stuff . It also gives leaves their green colour
- 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 are the three major photosythetic pigments?
- 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:I want to do some work with native american indigenous pigments.?
- Pigments from the past came from rocks, minerals, plants, and other natural materials. Those things are all still available. You can take classes at some universities that teach how to make your own paints, or dry pigments. For native American pigments, you have to research which tribe used which colors. To be totally authentic you could visit the tribe of your choice and see if you can learn from them. Sticking to your own zip code will not net you much, usually.
- 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.

Triarylcarbonium Pigments. Quinophthalone Pigments
- 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: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.
