  3. Pressure Flow Hypothesis

  4. 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. STEP 1: Food and water enters phloem of the stem through diffusion and osmosis. STEP 3: Water is being transferred in the xylem (going up) to keep balanced pressure. STEP 4: water is being transferred from the phloem – to maintain pressure in the phloem due to excess water from xylem from step 2. STEP 5: food is stored in the sink cell.
