Starch is produced in the chloroplast during photosynthesis. Starch is first converted to glucose and then to sucrose. Sucrose is transported throughout the plant body. After being transported to different parts of the plant body, it is used in metabolism and stored for the future. During the day when glucose is high, water loss results in insoluble sediment. During the night, insoluble carbohydrates are converted to soluble glucose. Excess glucose is converted to white matter under the action of amylase enzyme. Chloride accumulates in plant roots, stems, leaves, flowers, fruits and seeds. It is useful in making amino acids, proteins, fats etc.
