Respiration in plants
why not xylem???
The phytohormones that are involved in the vascular cambial activity are auxins, ethylene, gibberellins, cytokinins, abscisic acid and probably more to be discovered. Each one of these plant hormones are vital for regulation of cambial activity. Combination of different concentrations of these hormones is very important in plant metabolism
@ankita-maurya you can apply logic that xylem mostly consists of dead cells and water conducted passively but in cambium extensive growth occurs and more metabolism occurs
