Anatomical Difference between Dicot (Dorsiventral) Leaf and Monocot (Isobilateral) Leaf – Comparison Table

Dicot Leaf vs Monocot Leaf
(Difference between Dorsiventral and Isobilateral Leaf)

Dicot leaves are also called as dorsiventral leaves because they possess distinct dorsal and ventral sides. Monocot leaves are called isobilateral leaves since both the sides of monocot leaves are more or less similar. Dicot and monocot leaves show considerable differences both in their morphological and anatomical characteristics.

The present post discusses the Difference between Dicot and Monocot Leaf with a Comparison Table.
