what causes some plant petels and leaves to change colour in coloured water?

It is actually the vascular system of the plant.

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.

Chlorophyll is a green pigment and this gives the color to the grass and other plants.

I think its due to the varying colours of wavelengths\nof light. Chlorophyll B might be responsive to green light which is \nmostly reflected off the leaf,(thats why the leave is seen as green), as such there is no need fos so much chlorophyll B, and\nresources (e.g magnesium) are used in manufacturing more \nchlorophyll A. I'm not too sure about what  colour A is but its definitelt a colour in the rainbow.

It is due to genetical action because all the characters are controlled by genes, therefore the different colour of flower is also control by genes. If in a same plant different colour of genes are located in the same loculie or overlaped with each other than we will find different colour of flower in the same plant.

Vegetation emits in the infrared wavelength.  On false-color infrared mosaics, vegetation appears in red instead of green. The "redness" indicates vegetation density, type and whether growing on dry land or in a swamp. Grasslands appear light red, deciduous trees and croplands appear red, and coniferous forests appear dark red or maroon. Desert areas appear white and urban areas appear bluish green. Lakes, rivers and oceans appear in various shades of blue, dark blue for deep water and light blue for shallow or turbid water

Draw your own. They are not hard. \nH2O\nrain falls, runs into the pond. Sun evaporates the water, cloud forms, rain again.\nCO2\npond plants take in CO2, hey make sugar by photosynthesis using the sun for energy. A byproduct is O2. Pond animals breath the O2 and breath out CO2 which the plants use again.

it has to do with wavelength of the light.  the reason why plants are green is because they don't absorb the green light, green litht has a shorter wavelenght.  on the other hand If the object absorbs  blue, green and yellow light it will appear red  so I guess it does have to do with the material\nhope it helps

The plant will want water that causes it to work the least.\nI'd say, then, that lukewarm (room temp.) is best.\nCold water must be warmed up, and hot water (damaging the plant, burning the roots...bad) must be cooled down.

Yes. It does. Since there is more sugar in the water outside of the plant than there is in the water in the plant, the sugar solution will be hypertonic (higher concentration of solutes). This will cause osmosis to occur, causing water to flow out of the plant and into the sugar water to equilize the content. This will drain the vacuoles in the plant cells, and cause them to shrivel up inside of the cell wall.

It sounds like you've got an algae problem.  You've also got the chemical balance all screwed up.  You'll probably need to take a water sample somewhere and have it tested or get a pool man in to correct the problems.

Plants cannot change color in and of themselves.  What could happen, though, is that one plant could be pollinated by a neighboring plant and it would produce seed that contained some of the characteristics of both plants.

This is called the Mpemba effect.  It occurs for other reasons than the temperature of the water,  Mostly because of the different characteristics of water at different temperatures.  This Site has a lot of information about it.

I'm not sure exactly what you're asking, but if you put a few drops of food coloring in the water with a white flower (like a carnation), it will absorb the dye and the color.

Water travels through a network of 'veins' through out the plant. The cells are re-hydrated which causes them to expand like a balloon. Once the cells are all filled to capacity, they rest on each other. The cell membranes contain cellulose that helps them stand erect when fully hydrated.

Light hits water droplets and gets divided into seperate colors like the prism effect.

If you put a flower in water that has food coloring in it, the flower will take up the water and change color to the color of the food coloring.  Florists actually do this sometimes.
