IODINE TEST FOR STARCH The Iodine test is used to test for the presence of starch. Iodine solution — iodine dissolved in an aqueous solution of potassium iodide — reacts with the starch producing a purple black color. The colour can be detected visually with concentrations of iodine as low as 0.00002M at 20°C. However the intensity of the colour decreases with increasing temperature and with the presence of water-miscible‚ organic solvents such as ethanol. Also the test cannot be done at very low

Microscopes were invented in the 1600s. Robert Hooke first looked at a thin slice of cork in 1665; he saw "a lot of little boxes." These little boxes first reminded of the little rooms monks lived in‚ so he called them cells. Hooke observed the same pattern in the stems and roots of carrots and other plants. What Hooke still did not know‚ however‚ was that cells are the basic units of living things. Ten years later‚ the Dutch scientist Anton van Leeuwenhoek focused a microscope on what seemed to
