How the plants changes their colors?

it is the change in pigment colour.All plant cells have organells called plastids .Depending on the colour theyare divided in to3 groups\nGreen colour plastids are called chloroplasts they have chlorophyll pigment\nColored other then green(yellow ,red) plastids are called chromoplasts.They have xanthopyll and carotenois pigments\n\nColour less plastids are called leucoplasts\nThe main charactr of plastids is they can change from chloroplast to chromoplast or to lecucoplast or vice versa\n\nTha t is the reason we can see green bell peppers red and yellow ones\nEven th e leaf colour change in fall is also depends onthe same character

You can test growing different types of plants in different types of light or kinds/amounts of fertilizer.\n\nOne science project I saw that was visually interesting was done by a student who put white roses in different saturations of colored water (the white flower will turn colors.)\n\nOr could try growing mold on different kinds of food in different containers...putting eggs in different amounts of vinegar...\n\nGood luck.

WHY IS THE SUNSET RED?\nAs the sun begins to set, the light must travel farther through the atmosphere before it gets to you. More of the light is reflected and scattered. As less reaches you directly, the sun appears less bright. The color of the sun itself appears to change, first to orange and then to red. This is because even more of the short wavelength blues and greens are now scattered. Only the longer wavelengths are left in the direct beam that reaches your eyes.

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

Flowers which change color often do so based upon the acid or base content of the soil.\n\nThis might be the situation in your case.

In pigments (like paint) yellow and blue make green.\n\nIn lights, if you mix red and green lights, you get yellow light. If you add in blue light, you get white light, so for lights, yellow and blue make white.

Deciduous trees (i.e., trees that lose their leaves) undergo the process of abscission (falling off).  In the process of falling off, leaves change color.

It's the chlorophyll that makes them green.

The color of the plant leaves is what part of light it does not use.\n\nso a green leave uses all of the sun light but not the green wavelength, so it is reflected to your eyes. \nSo a green plant will not grow in green light.\n\nOf course, some plants are not green, but the same idea applies.

Sunflowers track the sun through changes in turgor pressure. Potassium ions get pumped into the underside of the flower on its shady side (the side where the cells aren't sensing as much blue light), which increases the turgor pressure, which causes the nearby motor cells to get longer and bend. As the sun moves across the sky, the pressure changes so that the head of the flower follows the sun. At night, when there isn't any sun, the pressure subsides, the motor cells go back to their normal size, and the flowers just kinda do whatever until the next morning. A plant's movement in response to light is called phototropism in general, but this kind of movement in particular is called heliotropism--it's diurnal, quicker, and reversible, as opposed to phototropism, which is...not.

The fall colors are the "natural" color of the leaves.  The same leaves look green during the spring and summer, because they are filled with chlorophyll, which is itself green.  When the tree stops growing in the cooler months, it stops producing chorophyll, which dies off, leaving the reds, oranges and yellows that we see.\n\nHope this helps.  Good luck!!

plants use the sunlight to turn nutrients into sugars to feed the plant they also take the toxins away from the plant when they go brown and drop off. Carbon dioxide and oxygen are released from them.

The photosynthetic pigments on the chloroplasts (more specifically, the thylakoid membranes) work by absorbing light.\n\nThe most abundant photosynthetic pigment is chlorophyll A and B, which like to absorb every color except green, which is reflected :)\n\nBecause there's a lot of green-reflecting chlorophyll, the chloroplasts appear green. Of course there are also pigments that reflect other colors (e.g. carotene reflects orange), but there are far fewer of those so we still see green.

When flowers drink colored water, they take in some chemicals that they are not supposed to. If you keep feeding the plants colored water, they will eventually die of lack of minerals that they are supposed to have.

leaves on house plants change colors if they arent properly cared for as well, I've never figured out why this is.\n\nI would check the species of the trees first.  Maybe you can clip a leaf thats green and put it in the fridge to see what color it turns, then try the freezer and see if it changes again.

because of chlorophyll content. after some time, the chlorophyll is removed from the fruit and other color pigments are created in the cells which gives fruits their colors.
