INTRODUCTION. The four major photosynthetic pigments have been separated by chromatography and identified. The color of the pigment comes from the wavelengths of light reflected (in other words, those not absorbed). They capture sunlight energy during photosynthesis, and are located in the membrane of thlyakoid. 5.2.1 Photosynthetic pigments Flashcards | Quizlet EXERCISE 4A: Plant Pigment Chromatography Paper chromatography is a useful techmque for separating and identifying pigments and other Leaves are green due to the presence of a green coloured pigment, called chlorophyll. a pigment that participates directly in the light reactions of photosynthesis Structure of chlorophyll a large molecule with a single magnesium atom in the head surrounded by alternating double and single bonds. Chlorophylls contain oxygen and nitrogen bonds, which hold more tightly to the paper; it does not make up as much as carotene, which does not form hydrogen bonds. This process of separation is called monodimensional ascending chromatography since the solution and pigments move upwards in one direction only. The substances visible … In this lesson we will explore what a pigment is and the role of chlorophyll in photosynthesis. The simple answer is that plants are green because they have green chloroplasts (organelles that carry out photosynthesis). The net result is that the internal CO 2 concentration in the leaf is very low, meaning that C 3 photosynthesis is not possible.
