In a dorsiventral leaf, location of palisade tissue and phloem is respectively on the ______ and ________ surfaces.

A

adaxial and abaxial

B

adaxial and adaxial

C

abaxial and adaxial

D

abaxial and abaxial

Text Solution

Verified by Experts

The correct Answer is:
A
Dorsiventral (bifacial) leaves are commonly horiozntal in orientation with distinct upper (adaxial) and lower (abaxial) surface. Mesophyll is distinguishable into palisade and spongy tissues with palisade usually restricted to the upper (adaxial) side. VAscular bundles are conjoint and collateral i.e.,they possess both xylem and phoem which lie on the same radius. Xylem lies towards the upper (Adaxial) side of leaf while phloem lies towards the lower (abaxial) side of leaf. most of the dicotyledonous leaves are dorsiventral.
