What does chromatography show about photosynthesis?
During photosynthesis, molecules referred to as pigments (due to the wavelength, thus color, they reflect) are used to capture light energy. Four primary pigments of green plants can easily be separated and identified using a technique called paper chromatography.
What are the 4 pigments in photosynthesis?
The plant pigments are found in chloroplasts on the thylakoids.
- 4 Plant Pigments.
- Chlorophyll a: Light to medium green. Main photosynthetic pigment.
- Chlorophyll b: Blue-green. Accessory Pigment.
- Carotene: Orange. Accessory Pigment.
- Xanthophyll: Yellow. Accessory Pigment.
What is the relationship between photosynthesis and pigments?
Photosynthetic cells contain special pigments that absorb light energy. Different pigments respond to different wavelengths of visible light. Chlorophyll, the primary pigment used in photosynthesis, reflects green light and absorbs red and blue light most strongly.
What is the conclusion of chromatography experiment?
Conclusion. Initially chromatographic techniques were used to separate substances based on their color as was the case with herbal pigments. With time its application area was extended considerably. Nowadays, chromatography is accepted as an extremely sensitive, and effective separation method.
What is the main photosynthetic pigment give evidence from the experiment?
Chlorophyll a is the most important photosynthetic pigment because it is directly involved in the conversion of light energy (photons) to chemical energy….

Why do some pigments travel further in chromatography?
The pigments are carried at different rates because they are not equally soluble. A pigment that is the most soluble will travel the greatest distance and a pigment that is less soluble will move a shorter distance.
How do different pigments affect the photosynthesis rate of plants?
Each pigment has a characteristic absorption spectrum describing how it absorbs or reflects different wavelengths of light. Wavelengths absorbed by chlorophyll and other photosynthetic pigments generate electrons to power photosynthesis.
What are the 3 main photosynthetic pigments?
In the diagram below, you can see the absorption spectra of three key pigments in photosynthesis: chlorophyll a, chlorophyll b, and β-carotene. The set of wavelengths that a pigment doesn’t absorb are reflected, and the reflected light is what we see as color.
What is the most important role of pigments in photosynthesis?
The importance of pigment in photosynthesis is that it helps absorb the energy from light. The free electrons at the molecular level in the chemical structure of these photosynthetic pigments revolve at certain energy levels.
What is chromatography report?
Chromatography. Chromatography’ is an analytical technique commonly used for separating a mixture of. chemical substances into its individual components, so that the individual components can be. thoroughly analyzed.
