Saps chromatography plant pigments
WebbThe primary photosynthetic pigment is chlorophyll which uses energy from light to excite electrons. The carotenoids are accessory pigments that “channel” more captured light energy to the chlorophyll.

Webb11 maj 2009 · Thin-layer chromatography has been used for the rapid separation of microgram amounts of pigments of marine phytoplankton, both from cultures and from the sea. The separation is carried out on plates coated with silica gel; the chromatogram is developed with a solvent consisting of petroleum ether (b.p. 60–80°), ethyl acetate and … WebbTY - JOUR T1 - Diversity in a Polymicrobial Community Revealed by Analysis of Viromes, Endolysins and CRISPR Spacers.

WebbThe aim is to extract photosynthetic pigments from leaves and to separate them using thin layer chromatography in order to see multiple different pigments from a single extract and to allow the identification of the pigments through the calculation of their Rf values and observations of their colour. WebbThe photosynthetic pigments in green plants absorb light energy and convert it to chemical energy. This energy is transferred to and trapped inside chemicals such as glucose and starch. Several different pigments are involved in the absorption of light.

Is it possible to have an Rf value greater than 1? Why or why not? In order to have an Rf value greater than 1 the pigment would have to move further than the solvent.

Chlorophylls tend to mask most other pigments in plants, so to see these other pigments, we need to separate them. farming system development approach
