When you are done with your readings dispose of the EtOH and the pigment extract in the
“waste ethanol” container.

Part 1 – Mastering Biology (36 points):
The novel setup integrates analysis of photosynthesis and morphology on a three dimensional level and thus enables a new way of multifactorial plant phenotyping.
High-class research fluorometer offering a variety of measuring and actinic light colors.
This is the reason leaves change color in the fall.
The colors of the carotenoids are familiar as the fall colors of leaves. As the leaves lose their chlorophyll, the more persistent carotenoids give the pleasant reds, yellows and oranges of the autumn foliage. is the most important of the carotenoids. , the color of tomatoes, is also a carotenoid.

Chlorophylla-a is the primary for in plants. Its structure is shown at left. It has the composition C55H72O5N4Mg. It exhibits a grass-green visual color and absorption peaks at 430nm and 662nm. It occurs in all photosynthetic organisms except photosynthetic bacteria.

Chlorophyll is a green pigment that is responsible for a plant'sÂ .Chlorophyll is the green pigment used for photosynthesis Minor What is the green pigment needed for photosynthesis?
What color of light is least effective in driving photosynthesis
Photosynthesis can only happen in the presence of light
energy and chlorophyll.
We often think of
sunlight as a single
“white” wavelength, but
in reality it is a continuum
of wavelengths – each
wavelength representing a
different color of light.
The Effect of Green Light on Plants The Color Spectrum
Energy is inversely proportional to wavelength,
so that long wavelengths, such as radio waves carry less energy than short
wavelengths such as gamma rays.

pigments that absorb light energy for use in photosynthesis.

Consequently, green is the color generally associated with plants.
The carotenoids (Figure 4) form a family of pigments that absorb light in the blue range
giving this class of pigments color which ranges from pale yellow to orange to red.
