WebFeb 27, 2024 · Bulk flow across capillary walls is an active process that is driven by the hydrostatic pressure of the blood in the capillaries. This pressure forces the plasma and its dissolved substances, including small molecules, through the walls. This process is important for the movement of fluids and nutrients into the tissues from the blood. Webbulk flow in phloem is driven by (1) - osmosis dissolved substance in phloem cells (1) water potential or those cells which cause (2) to move into them -reduce - water increased (1) pressure then moves substance in phloem form (2) such as leaf to a (3) such as a developing fruit. - turgor -source - sink The plant shoot system absorbs carbon dioxide
