| Monocots have parallel venation | Smilax, Alocasia, Colocasia have reticulate venation | Monocots in Araceae/Liliaceae-related families |
| Dicots have reticulate venation | Calophyllum (Clusiaceae) has parallel venation | Few dicot exceptions exist |
| Fabaceae has diadelphous stamens | Cassia (Caesalpinioideae) has free (polyandrous) stamens | Cassia tested in NEET 2016 |
| Fabaceae has vexillary aestivation | Cassia has imbricate aestivation | Cassia NOT papilionaceous |
| Monocots cannot undergo secondary growth | Dracaena, Yucca undergo anomalous secondary growth | Via primary thickening meristem — not true vascular cambium |
| Xylem parenchyma is the only living xylem element | In some plants, parenchyma may be found transfusion tissue in gymnosperm leaves | Specifically in gymnosperm needle anatomy |
| Companion cells are paired with sieve tubes | Gymnosperms have albuminous cells (not companion cells) instead | Albuminous cells are functionally analogous |
| Asteraceae has inferior ovary | Most Asteraceae have inferior, but some have semi-inferior | Generally considered inferior in NEET |
| Stomata absent in submerged aquatic plants | Vallisneria (submerged) has stomata in some parts | Complex exception |
| Root hairs are from root epidermal cells | In orchids, aerial roots have velamen (multilayered absorptive epidermis) | Velamen absorbs moisture from air |
