Cross-section of the leaf stained with Alcian blue-safranin
and observed with the objective of 10x. We can discern the
upper and lower
epidermis,
the mesophyll (showing the
spongy
and
palisade parenchyma),
and the central
vascular bundle
of the leaf with a ramification cut longitudinally (on the
left). Under the vascular bundle are placed numerous
sclereids (yellow)
cut tranverselly and a zone of
collenchyma
