Internal Structure of Dorsivental Leaf (mango leaf)

Dorsiventral leaves are found in dicots. The vertical section of a dorsiventral leaf contains three distinct parts: Epidermis, Mesophyll and Vascular system.

The epidermis is present on both upper surface (adaxial epidermis) and lower surface (abaxial epidermis) of the leaf has a conspicuous cuticle. Mesophyll tissue of the leaf present between the adaxial and abaxial epidermises. Vascular system includes vascular bundles, which can be seen in the veins and the midrib.

Major Internal Structure of Dorsivental Leaf are pointed below:

(i) It is green, compressed with wide lamina

(ii) Leaf blade is enriched with reticulate venation

(iii) Mesophyll tissue is present and is composed of palisade parenchyma and spongy parenchyma

(iv) Vascular bundles are conjoint and closed; i.e. cambium is absent in the vascular bundle. Vascular bundle are surrounded by one layered cells known as bundle sheath

(v) Stomata are present on the lower epidermis

(vi) Palisade parenchyma is present towards the upper epidermis, while spongy parenchyma is present towards the lower epidermis.
