The Role Of Pigments In Red Wandering Jews
Plant Pigment Lab
Question: What pigments are present in Red Wandering Jews?
Background: A leaf is filled with many pigments. The pigments are usually masked by the prevalence of the green chlorophyll. Anothocyanin(red or purple), carotene(orange), and xanthrophyll(yellow) are found in different proportions in different leaves. Leaf pigments can be separated by using paper chromatography. Paper chromatography is a technique that extracts pigments into a paper filter called chromatogram.
What are the pigments are in Red Wondering Jews?
Carotenoids
These pigments primarily absorb in the blue wavelengths, allowing the longer wavelengths to be scattered and producing the yellow color. In autumn foliage, the carotenoids are left over in the chloroplasts and revealed from the loss of chlorophyll. …show more content…
They are produced in chloroplasts in the photosynthetic tissues of the leaf. Chlorophyll is normally broken down towards the end of the leaf life span, and much of the nitrogen is reabsorbed by the plant.
Anthocyanins
These are responsible for the pink-red colors of most flower petals, of most red fruits (like apples) and almost all red leaves during the autumn. Anthocyanins absorb light in the blue-green wavelengths, allowing the red wavelengths to be scattered by the plant tissues to make these organs visible to us as red.
Hypothesis: If we test the Red Wandering Jew leaves for pigments then we will find anthocyanin in the leaves because there is purple in the leaves.
Control Variable:
