1. Monocot leaves typically exhibit a parallel venation pattern, whereas dicot leaves display a reticulate venation pattern.
2. Monocot leaves are generally smaller in size and thickness than dicot leaves.
3. Dicot leaves usually have sheathing leaf bases, unlike monocot leaves.
4. Monocot leaves possess multiple main veins that originate from the same point at the base.

Two leaf cross-sections A and B are examined. Section A shows distinct palisade parenchyma on the adaxial surface and spongy parenchyma on the abaxial surface with stomata mostly on the lower surface.
Section B shows uniform mesophyll without differentiation and stomata on both surfaces. Based on this information:
1. Both are dicot leaves showing variation
2. A is a dicot leaf (dorsiventral) and B is a monocot leaf (isobilateral)
3. Both are monocot leaves showing variation
4. A is a monocot leaf and B is a dicot leaf

One important difference between the anatomy of roots and the anatomy of leaves is that
1. only leaves have phloem and only roots have xylem.
2. root cells have cell walls and leaf cells do not.
3. a waxy cuticle covers leaves but is absent from roots.
4. vascular tissue is found in roots but is absent from leaves
