STEP 1: Food and water enters phloem of the stem through diffusion and osmosis. . STEP 2: Water from xylem is transferred to the phloem to help break down/dissolve food in the phloem. The water pressure is kept at low. . Done by : Annabel Diong . A plant body. . Introduction . This slideshow presentation . will explain in detail about how the xylem in the plant works and how it transports water, how a desert plant absorbs water, the structure of both desert and regular plant, and the xylems significance. It will also contain many images showing what the xylem is and finally how the xylems affects the photosynthesis. . (3060 - Part . II). Soil Water. Precipitation and Evaporation.
