Vedclass · Answer

(A) Secondary growth is the growth that results from cell division in the cambia or lateral meristems and that causes the stems and roots to thicken. In dicotyledonous plants,secondary growth is a normal phenomenon. $Cucurbita$ is a dicotyledonous plant,and therefore,it exhibits secondary growth. $Helianthus$ (sunflower) is also a dicot,but in the context of typical textbook examples for secondary growth in stems,$Cucurbita$ is frequently cited. $Hordeum$ (barley) is a monocot and does not show normal secondary growth. $Dracaena$ is a monocot that shows anomalous secondary growth,but $Cucurbita$ is the most standard answer for typical secondary growth in dicots.
