Q:pigments??
Photons are the packets of energy that light delivers. Different colors of light have different amounts of energy in each of the light's photons. So, green light's photons have different amounts of energy from red light's photons. Different materials absorb different amounts of energy via photons very selectively. It has to do with the energy states of the molecules, and the electrons that are in the outer shell.
Q:do all leaves extract contain the same pigments??why?
Absolutely not. Leaf pigments, just to name a few, may include chlorophyll, carotenes, lutein, anthocyanins. Not only will pigment content vary between plant species, but pigment content will vary in individual plants seasonally.

Q:complete the table below to organize your thoughts about plant pigments?
pigment: .... reflected color to eyes .. what color of light it absorbs Chl a reflects green spectra between the blue and red absorption peaks. Some is absorbed at blue 450nm but most absorbed at red 680 - 700nm. Chl b reflects green spectra between the blue and red absorption peaks with a difference in which peak is stronger. Most is absorbed at blue 470 but also some at blue 430 and red 640 nm. Cartenoids reflect yellow, orange, or red and absorbs blue to blue-green light spectra. Xanthophyll absorbs well at 400-530 nm. Xanthophylls are a common sub class of the carotenoid pigment group. Beta-carotene absorbs most strongly between 400-500 nm.
