DISCUSSION |
1. What is carotene?
Carotene is an orange or red plant pigment found in carrots and many other plant structures. It is a terpenoid hydrocarbon with several isomers, of which one ( beta carotene ) is important in the diet as a precursor of vitamin A. 2. What is xanthophylls? Xanthophylls are the typical yellow pigments of leaves. These are oxygenated carotenoids that are synthesized within the plastids.Xanthophylls do not require light for synthesis, so that xanthophylls are present in all young leaves as well as in etiolated leaves. 3. What is Chlorophyll a? Chlorophyll a is a specific form of chlorophyll used in oxygenic photosynthesis. It absorbs most energy from wavelengths of violet-blue and orange-red light. It also reflects green/yellow light, and as such contributes to the observed green color of most plants. 4. What is Chlorophyll b? Chlorophyll b is a form of chlorophyll which helps in photosynthesis by absorbing light energy. It is more soluble than chlorophyll a in polarsolvents because of its carbonyl group. Its color is yellow, and it primarily absorbs blue light |
CONCLUSION |
There are 4 pigment present in leaf that is from the top of the chromatography paper start with Carotene, Xanthophyll, Chlorophyll a, Chlorophyll b. Hypothesis accepted.
