Materials: a leaf, a 100 mL beaker, 10 mL ethanol, a hot plate, a power outlet to plug the hot plate into, a Petri dish, goggles, supervision (if you're a kid)
Suppose you're working with a spinach leaf. Put it into a 100 mL beaker. Add 10 mL of ethanol to it. Place the beaker with ethanol on a hot plate and set the heat to 2 or 3. Do not crush the leaf or boil the ethanol, which will turn green as chlorophyll gets extracted. Turn off the heat when the ethanol is nicely green. Let the solution cool, put the leaf in a Petri dish or discard it, and pour the chlorophyll extract someplace where you can observe it better. That's the extracted chlorophyll! You can use this method with any leaf, really. Spinach was just an example.

Why does spinach extract turn red in bright light?
I don't know the source of your "bright light". If it's sunlight, which of course has some UV in it, or if you take the extract into a dark room and shine a "black light" on it, you will see fluorescence. The source of the red color is chlorophyll. When in place in the leaf, the electrons of chlorophyll absorb solar energy. These excited electrons then fall into an electron transport chain that will strip them of the added energy, using that energy to form ATP and NADPH. The red color you see when you illuminate chlorophyll in a spinach extract with UV is the fall of those "excited state electrons" back into their "ground state". In falling, they shed their energy in the form of red light.
Why do spinach look green papaya yellow and edible part of watermillon red?
Spinach has chlorophyll (green). Watermelon has carotene(red) inside it.

What stores food or contains pigment in cells?
chlorophyll is the green pigmentation in plants. Photosynthesis is the method used by plants to utilise carbon dioxide and the suns energy to form glucose to use as food other than the minerals it is able to extract from the earth.

Does red cabbage have more chlorophyll than spinach?
Chlorophyll is substance that is found in GREEN LEAFY VEGETABLES and not in red-coloured vegetables as chlorophyll is the major cause for the colour green in vegetables

chlorophyll
What types of pigment are usually found in all leaves extract?
chlorophyll
What are the types of pigments that are usually found in all leaves?
Depends upon solvent used . Alcohlic extract have chlorophyll .
What is the liquid that destroys chlorophyll?
Organic solvents like alchohol, acetone, ether etc destroy chlorophyll. some of these solvents are used to extract chlorophyll from plant leaves.
Can you extract chlorophyll froma green light?
ye you can do it. but it is happening better in blue light.
