    Tittle: Separation of leaves pigment. Introduction The photosynthetic pigment is used to absorb light during the process of photosynthesis. There are five pigments usually found in spinach leaves: Carotene (yellow)‚ Phaeophytin (yellow-grey)‚ Xanthophyll (yellow-brown)‚ Chlorophyll a (blue-green)‚ Chlorophyll b(green). Photosynthetic pigment is located in the chloroplast of the leaf. The function of chlorophyll a and chlorophyll b is to trap red and blue violet light when they carry out photosynthesis

    use the process of chromatography to separate plant pigments. To compare the plant pigments found in spinach and red leaf lettuce leaves. Hypotheses: I believe the spinach leaf in the acetone will have a higher pigment of chlorophyll a and the red leaf lettuce will have a higher pigment of anthocyanin. I believe the spinach leaf in distilled water will have a higher pigment of chlorophyll a and the red leaf lettuce will have a higher pigment of anthocyanin. Discussion Questions: 1. Describe

    INTRODUCTION Plant pigments consist of four main chemicals. These are Chlorophylls‚ The carotenoids‚ Anthocyanin and Betacaine. The aims of this experiment is to separate the plant pigment into different colours using solvents and column chromatography. The hypothesis of this experiment is that this plant pigment from spinach will contain the chlorophyll pigment or may contain the others too. Chlorophyll: Chlorophyll a is the main component of the plant pigments. This is used for the most

    Experiment 5 Analysis of Plant Pigment Purpose: Chromatography is used for separation. In this case the separation of plant pigments. After placing the plant sample in the column the separation will be easy to see and the samples will be analyzed using VIS spectrophotometry. This is used to isolate and identify the different lipids causing the different pigmentations. Introduction: Lipids are chemically diverse substances found in cells. Lipids are water-insoluble‚ structural components

    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 elodea plants are able to grow and photosynthesise the best. This experiment was consisted of 4 different colours of light‚ Blue‚ Green‚ Red and Purple. Hypothesis: I predict that the plant under blue and purple light will have a higher photosynthetic rate because according to the colour spectrum‚ they are of shorter wavelength thus they have a higher energy. The red light and green light will have lower
