transpiration pull is –as a result of loss of water from mesophyll cell the diffusion pressure deficit increases .due to which these cell absorbs water from adjoining cell ultimately the water is absorbed from xylem elements of vascular bundle of leaf.since the xylem elements are filled with continous water column a tension or pull develop at the top of column.this is known as trans piration pull.
