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) |
Select the correct pair.
1. Cells of medullary rays that form part of a cambial ring - Interfascicular cambium
2. Loose parenchyma cells rupturing the epidermis and forming a lens-shaped opening in the bark - Spongy parenchyma
3. Large colorless empty cells in the epidermis of grass leaves - Subsidiary cells
4. In dicot leaves, vascular bundles are surrounded by large thick-walled cells - Conjunctive tissue
