The surface that faces the stem upwardly is designated as upper surface or adaxial surface whereas the other surface is the lower or abaxial surface. Anatomically a leaf comprises the usual three [...]
The upcoming discussion will update you about the difference between vascular bundle of monocot stem and vascular bundle of dicot stem. Difference # Vascular Bundle of Monocot Stem: 1. The vascular bundles are scattered in the ground tissue. 2. They are of different sizes, the smaller being restricted to peripheral sides. 3. They appear to be embedded in ground tissue. [...]
