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

Difference between Dorsiventral and Isobilateral Leaf

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.

Dicot Leaf Cross Section (Dorsiventral Leaf)
(Anatomical Structure of a Dicot Leaf- Ixora, Mangifera, Hibiscus)

Ø  Leaves are structurally well adapted to perform the photosynthesis, transpiration and gaseous exchange.

Ø  A leaf composed of:

(1). Leaf blade: also called leaf lamina is the flattened expanded part of the leaf chiefly composed of mesophyll tissue and vascular bundles.

(2). Petiole: the stack of leaf

Ø  Based on the differentiation of mesophyll, two categories of leaves are present among Angiosperms

(1). Dorsiventral Leaf

(2). Isobilateral Leaf

(1). Dorsiventral Leaf:

Ø  Also called bifacial leaf.

Ø  They have anatomically different dorsal and ventral sides.

Ø  The mesophyll tissue is differentiated into upper palisade and lower spongy tissues.
