can you think of some plants that contain chlorophyll?

All plants have chlorophyll..........................

As per above, red and blue wavelengths are generally the most important because chlorophyll absorbs these colors to a greater extent.  Greens and yellows are often reflected, resulting in the colors of plants that we see.  When the color of light is red or blue, chlorophyll are more apt to absorb the light, thus engendering an increase in the rate of photosynthesis.

chlorophyll is needed in the process of photosynthesis. during the photosynthesis oxigen and glucose are produced. when glucose has to be transported from the leaves to the other parts of plants body it is changed into saccharose (sucrose).\nwhen it reaches for example roots and other parts it is transformed into starch. so it is obvious that in the soil there is no sunlight and in the roots there is no chlorophyll, but the process takes place. chlorophyll and sunlight are not needed.

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.

plants need minerals as their food through the process of photosynthesis as people need minerals, vitamins, carbohydrates, protein fats , oil, etc as food through the process of digestion and assimilation

Various plants have different accessory pigments in addition to chlorophyll.These various pigments are more efficient at using different wavelengths or under low or bright light conditions. For instance, many rain forest plants that live on the forest floor have a reddish undercoating to trap certain wavelengths of light. So, the various colors are adaptations to handle different growing conditions and allow the plant to grow adequately in areas where other plants cannot grow well.

No the plant could not produce starch without chlorophyll. They synthesize the sugar from water and carbon dioxide in a process called photosynthesis.

Chlorophyll only absorbs specific wavelengths of light. All other light is reflected. The reflected light is what allows us to perceive leaves as being green.

the colour of plants depend on various colouring agents called pigments. some pigments (cytochromes) found in the leaf include chlorophylla,b(green), carotenoids(yellow-orange), xanthophylls(yellow). the colour of the leaf depends on the proportion in which these pigments are present(as these pigments play an important role in photosynthesis, they are present in the chloroplasts present in the leaves). also chlorophyll a is called universal pigment as all plants contain it and other pigments are called accesory pigments.

Green plants have of course cell walls as do non-green ones. That is the characteristic feature of plants. They also have a nucleus, which is the same for many eukaryotic cells. I do not know what exactly you are referring to by non-green plants but the only plants that do not photosynthesise, in the strictest sense, are plant cells in cultures. This is because the media provide the necessary nutrients and resources and it is no use spending energy on synthesizing something that can be earned with no energy expenditure. These cells too have cells walls and nuclei. Animal cells do not have cells walls, also a distinguishing feature from plant cells. Several of them have nuclei, sometimes more than one, but in some speacialised mature cells such as red blood cells, there are no nuclei.\n\nPlants do not have centrioles where as animals do. Plants have chloroplasts (green plants), non-green ones do not, animals do not. Plants have a very dominant vacuole that sereves as a cenntre for turgor pressure regulator, hydrolytic enzymes container and pretty much function like lysosomes in animals, which are absent in plants.

Carotenoids.  Those are yellow and orange pigments that are found in many plants.  The best known of them is probably beta carotene (the most common isomer of carotene, which gives this category of pigments its name), found in carrots.

You can not have some other mineral that is black. Chlorophyll is a chelated metal compound. Such compounds derive their colour from the emission spectrum of the d shell electrons. \n\nEmmission spectra are quantised because electrons are quantised. There are only a finite number of transitions available, and each transition emits at a specific frequency. When the incident light is visible the d electrons can only emit in  one very specific part of the spectrum. That means that the colour of a pigment molecule like chlorophyll or haemoglobin can only have one very specific colour.\n\nIn order for a plant to be black it would need to emit (and hence absorb) across the entire spectrum. That is not possible with a single transition metal compound.\n\nIt is possible with 4 or more different compounds, but that would require the plant to waste resources building compounds that absorb less common, and hence less energetically favourable, wavelengths. Such a situation could never evolve because any such plant would be outcompeted by green plants.

Only plants have chloroplasts and cell walls.

just fyi i would have made this a biology question but anyway, chlorophyll a and b would be present in both leaves its not one or the other.  this sounds like homework don't you think that you should be figuring this out on your own.  i'll give you a couple hints.  you need a solute so that you can separate the pigments.  the pigments  will travel farther if the are less soluble.  Anyway thats all i'm giving you good luck.

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.

Plant cells contain chlorophyll. There are a few types of chlorophyll. Some are high energy and others lower energy.  Every species of plant has different ratios of these various chlorophyll molecules.\n\nAs light energy hits a plant leaf, you get conversion of energy. If more light hits the plant, then more energy up to a point. You will reach a couple of roadblocks. The first is the theoretical maximum the chlorophyll can produce. You have saturated it and it can do no more. I say theoretical as this level will often burn the plant before it is reached. The other roadblock is that as you increase the energy you may move or shif out of the optimal range for that species. So they may have lot of chlorophyll A and little Chlorphyll C and if you shifted to the energy wavelength of C total energy production would decrease even though you increased available source energy.\n\nSince this sounds like a school project, I will only point you in the proper directon.  Look up different types of chlorophyll. Look up the types found in tomato plants. Both are easily searched on Yahoo or Google. Then look up evergy levels of saturation on those types and then look up ebergy levels of light intensity. You could then make a simple chart showing at what level the prduction will shift and then decrease.

chloroplast contain membbranous structures which are pilled in stacks called grana\ngrana contain the light-trapping pigment chlorophyll. chlorophyll is the most abundant photosynthetic pigment in plants\ngrana are embedded in a gel-like matrix called stroma\nstroma is the site where the dark reaction occur and the enzyme responsible for the dark reaction of photosynthesis also found here\nstarch grains which act as a temporary storage for the products of photosynthesis are also found in the stroma\n\nfor more extra information try to find it at wikipedia
