Cut a transverse section of young stem of a plant from your school garden and observe it under the microscope. How would you as certain whether it is a monocot stem or a dicot stem. Give reasons.
If you see scattered, several vascular bundles with sclerenchymatous bundle sheath, undifferentiated ground tissue and no pith is there, then the transverse section is of a monocot stem.
If the section has vascular bundles arranged in a ring, differentiated ground tissue into cortex, endodermis, pericycle and pith, then the section is of dicots stem.
