The main function of the flower stock is transporting food in the form of water and nutrients to different parts of the plant with the help of xylem and phloem. Xylem helps in transporting cells that help in carrying water and minerals from the roots while phloem transports food in the form of sugar to all parts of the plant. The stock also helps in keeping the the flower steady above the plant folliage. This directly helps in the process of pollination of the plant. The flower that is held steady above the folliage attracts bees and other insects through which it continues the process of pollination.
