Identify the incorrect comparison between monocots and dicots in general:
| Character | Monocots | Dicots | |
| 1. | Leaves | Parallel venation | Reticulate venation |
| 2. | Roots | Primary root of short duration, replaced by adventitial roots forming fibrous or fleshy root systems | Develops from the radicle. Primary root often persists forming strong tap roots and secondary roots |
| 3. | Plant stem: Vascular bundles | Ring of primary bundles with cambium, differentiated into cortex and stele | Numerous scattered bundles in ground parenchyma, cambium mostly absent, no differentiation between cortical and stelar regions |
| 4. | Flowers | Parts in threes (trimerous) or multiples of three | Fours (tetramerous) or fives (pentamerous) |
Subtopic: Anatomy of Root | Dicot Stem | Monocot Stem | Dicot Leaf | Monocot Leaf | Activity of Vascular Cambium (OLD NCERT) |
