chromatography works because the ink used contains several dyes (pigments) that when place on porous paper are dissolved in a solvent by capillary action. When the pigments (solutes) are dissolved in the solvent (water & alcohol mixture) they move through the paper at different rates depending on their solubility. The more soluble the pigments are the faster they will move through the paper. Paper chromatography is most commonly used to separate pigments‚ dyes and inks. In forensics‚ paper chromatography

Pigments includes both organic and nonorganic compounds and materials that are added to the other two substances to create a certain color. Binders provide support for the pigment‚ and the solvent dissolves these substances into liquid form. 3. What are polymers? Polymers are substances made up of atoms with the atoms arranged

Roots The root system of a flowering plant begins its development from the hypocotyl of the embryo of the seed which gives rise to the primary root. Roots generally grow downwards into the soil (positively geotropic) and upwards (negatively geotropic). Roots do not bear leaves and therefore no nodes are present.Two kinds of root systems can be distinguished in flowering plants: tap root systems and adventitious root systems. Usually dicotyledons posses tap root systems and monocotyledons adventitious
