Practice question

Monocots comprise about quarter of angiosperm species defined by single cotyledon storage, parallel or arched leaf venation where major veins run longitudinally converging apically with minor transverse commissural veinlets interconnecting, scattered atactostele vascular arrangement, adventitious root system fibrous, trimerous floral whorls multiples three. Reticulate venation forms hierarchical network dominated by eudicots, two cotyledons storage, pentamerous or tetramerous perianth typical eudicots, not monocots. Secondary growth limited due to absence bifacial cambium, though anomalous secondary growth occurs in palms and agaves via monocot cambium. Parallel venation therefore reliable field diagnostic easily observed.
