which pigment are present in potato ? ..are th pigments located in chloroplast, chromoplast, or vacules?

The actual potato you eat is in the ground so it does not have chloroplasts or chromoplasts, and the vacules never have pigment. the part of the spud that has pigment is the above ground part and the pigment is in the chloroplasts.

plant cells have vacuoles and chloroplasts while animal cells dont. plant cells synthesize their own foods while animal cells dont.\n\nribosomes are the organelles that synthesize proteins using RNA from the nucleus.\n\nI just cant seem to remember what the answer of the third question was.

The mesophyll is the leaf tissue where most of the chloroplasts are found and photosynthesis takes place. The mesophyll is differentiated into the palaside mesophyll and teh spongy mesophyll. \n\nThe palaside mesophyll is made up of one or more layers of narrow, elongated parenchyma cells; these cells have a higher concentration of chloroplasts, and therefore these are the cells in which most of the photosynthesis takes place. \n\n----\nOf course - photosynthesis takes place in *all* the cells which have chloroplasts. But I don't think that is what this question is about.

The pigments belong to a group of chemicals called flavonoids.\nPlants make all the things they need from carbon dioxide in the air and water from the soil (this is photosynthesis) plus minerals (e.g. nitrates, sulphates, phosphates, etc.)from the soil.\nThe pigment you mention and any other colour you see in plants is made by the plant.\nPlants make themselves.

chloroplast of course!\nPHOTOSYNTHESIS!!

This question has been asked numerous times.  Theses are User estee06's words.  I put a link below.\n \n\nApples and other produce (e.g., pears, bananas, peaches, potatoes) contain an enzyme (called polyphenol oxidase or tyrosinase) that reacts with oxygen and iron-containing phenols that are also found in the apple. The oxidation reaction basically forms a sort of rust on the surface of the fruit. \n\nYou see the browning when the fruit is cut or bruised because these actions damage the cells in the fruit, allowing oxygen in the air to react with the enzyme and other chemicals

Chlorophyll comes in multiple colors, the pigment itself is irrelevent. The the only thing that matters is that the chlorophyll is present.

a chloroplast contains chlorophyll which is needed for the plant to photosynthesise, or make food. the chloroplasts are only found in plants, as we do not need to make any food... we take our food from the surroundings.

I will split your question in to two parts viz. 1) Photosynthesis and 2) Stomata; so that you can easily understand it.\n 1) PHOTOSYNTHESIS-: for this function entire middle portion of a leaf contributes, it is called MESOPHYLL in botanical language.(Meso = middle or in between; Phyll = refers to leaf). It is located in between the upper and the lower skin or the epidermis of a leaf (Plural epidermes).\n In most of the leaves the MESOPHYLL is again distinguished it to Upper PALISDE tissue and the Lower SPONGY LAYER.\n Both of them are full of chloroplast and do the function of photosynthesis; but there is a difference.\n The palisade cells are located near the upper epidermis,they are elongated,test tube like in appearence and are placed at right angle to the upper epidermis like upright test tubes.( try to see the meaning of palisade in a good dictionary, it is interesting.). These palisade cells are very closely packed with very little space in between and each of them is literally packed with chloroplasts. That is why a leaf appears greener on its upper surface.Thus, they are ideally located to receive maximum sun light and do maximum photosynthesis.\n\nThe Spongy layer , on the other hand , is located near the lower epidermis of a leaf. The cells are spherical or potato shaped and with lots of intercellular spaces between them. Each cell of this layer contains (comparitively) less or far less number of chloroplasts than the palisade of the same leaf.That is why the same leaf appears pale green on its lower surface.\n This Spongy layer does the function of photosynthesis no doubt ; but it is less in quantity than that of Palisade of the same leaf. This is because it is located rather away from the light source and its main function is to help the leaf in gaseous exchange, that is why there are so many intercellular spaces.( here Photosynthesis is over)... \n\n2) STOMATA (singular stoma) -: These breathing pores are neither IN the palisade layer nor IN the spongy layer. They are a PART of the the two epidermes( upper and lower ).\n If one compares the quantity and the distribution of these stomata of one and the same leaf then they are more on the lower epidermis to help the spongy tissue in gaseous exchange during photosynthesis/respiration.\n On the upper epidermis they are far less in number to reduce or prevent exessive water loss due to transpiration.\nIn many desert plants they are either totally absent from the upper epidermis or located in sunken pits for the same reason.\nI hope you got what you sought. Bye.

what exactly is your question? \nYour potato is growing in the dark because it is what potatoes do if you give them time and water/moisture. If potatoes wouldn't do that there wouldn't be any potatoes around, they would have long ago gone extinct. \nIt is albino because light is needed to induce the syntesis of chlorophyll. It will also grow taller and only have tiny leaf-like structures because under normal circumstances a growing potato experiences permanent darkness is under the ground in the soil. It's only way to develop into a normal potato plant is grow like crazy upwards so it gets out of the ground and gets some sunlight. It is pointless to put energy at this stage in developing leaves. \nIf you never give it light it will grow until all the energy stored in the potato is used up and then it dies.

Not sure what you mean by "affect", but potatoes contain catalase which breaks down hydrogen peroxide to water and oxygen. Apple and yeast probably have similar enzymes.

Short answer yes it is true\n\nlong answer\n\nhttp://en.wikipedia.org/wiki/Calvin_cycle\n\nre previous answer\n\nChloroplasts are flat discs usually 2-10 micrometer in diameter and 1 micrometer thick. The chloroplast has a two membrane envelope termed the Inner & Outer membrane respectively. Between these two layers is the intermembrane space.\n\nThe fluid within the chloroplast is called the stroma, corresponding to the cytoplasm of the bacterium, and contains tiny circular DNA and ribosomes, though most of their proteins are encoded by genes contained in the cell nucleus, with the protein products transported to the chloroplast.\n\nWithin the stroma are stacks of thylakoids, the sub-organelles where photosynthesis actually takes place. A stack of thylakoids is called a granum (plural: grana). A thylakoid looks like a flattened disk, and inside is an empty area called the thylakoid space or lumen. The photosynthesis reaction takes place on the membrane of the thylakoid, and, as is also the case with mitochondria, involves the coupling of cross-membrane fluxes with biosynthesis.

Good question\nFlower colors of red, pink, blue and purple come mainly from the pigments called anthocyanins. Anthocyanins are water soluble pigments in the class of \nchemicals called flavanoids, which are phenolics. Anthocyanins are found in the \ncell vacuoles and are glucosides meaning they contain a sugar molecule. \n\nA classic experiment uses the anthocyanins in red cabbage as a pH indicator \nbecause anthocyanins change color depending on the pH. You could do the same \nthing with flower petals. An easy way is to crush a red rose petal on a white \nplate with the back of a spoon and add either vinegar (acid) or baking soda \n(base) and note the color change. A college lab manual has an experiment on \nchromatography of flower anthocyanins (Witham et al. 1971).\n\nFlowers may also contain another class of pigments called carotenoids, which \nare responsible for red in tomato and orange in carrot root. Carotenoids are \nred, yellow and orange in color. They do not reside in the vacuole but in \norganelles called plastids, either in green chloroplasts or in nongreen \nchromoplasts

Probably a contribution of two things:\n\n1. oxidisation of the oxygen in the air\n2. the potato absorbing water from the air.

Tissues of vascular plant leaves: Leaves are cloaked by a single layer of cells called the epidermis. It protects the leaf from physical damage and pathogens. A transparent, waxy, colorless cuticle coats the epidermis. The stomata ( small holes) are located on the lower epidermis of the leaf. The stomata allow gases and water vapor into and out of the leaf. Each stoma is controlled by two bean shaped guard cells. The palisade mesophyll is a layer of elongated cells containing chloroplasts found just under the upper epidermis. The majority of photosynthesis takes place within this area. Just below the palisade mesophyll is an area of loosely packed parenchyma called the spongy mesophyll. The spongy mesophyll contains air spaces in which gases circulate. The petiole of the leaf connects the blade with the stem. The vascular tissues pass through with the xylem positioned in the top section of the vein while the phloem occupies the lower section.

Green. Carotene sends the light it absorbs on to it's old friend, chlorophyll. Ever see the leaves of carrots?
