In dicot stems, the cells of cambium present between primary xylem and primary phloem are the intrafasicular cambium. Water must completely fill the pipeline. The lungs and airways. Secondary growth in trees is the result of cambial activity that produces both acropetal conducting xylem cells and basipetal conducting phloem cells (Larcher 2003).As dynamics of secondary growth are under the control of environmental factors (Agusti and Greb 2013), analysis at the cellular level is a proven tool to study their effects on tree growth (Griar 2012; Deslauriers et al.
