Aside from cotyledon number, other broad differences have been noted between monocots and dicots, although these have proven to be differences primarily between monocots and eudicots. Many early-diverging dicot groups have monocot characteristics such as scattered vascular bundles, trimerous flowers, and non-tricolpate pollen. [5] In addition ...
The eudicots or eudicotyledons are flowering plants that have two seed leaves (cotyledons) upon germination. [1] The term derives from dicotyledon (etymologically, eu = true; di = two; cotyledon = seed leaf). Historically, authors have used the terms tricolpates or non-magnoliid dicots.
Magnoliids, Magnoliidae or Magnolianae are a clade of flowering plants.With more than 10,000 species, including magnolias, nutmeg, bay laurel, cinnamon, avocado, black pepper, tulip tree and many others, it is the third-largest group of angiosperms after the eudicots and monocots. [3]
The traditionally listed differences between monocots and dicots are as follows. This is a broad sketch only, not invariably applicable, as there are a number of exceptions. The differences indicated are more true for monocots versus eudicots .

The visible part of the monocot plant (left) is actually the first true leaf produced from the meristem; the cotyledon itself remains within the seed Schematic of epigeal vs hypogeal germination Peanut seeds split in half, showing the embryos with cotyledons and primordial root Two ...
The term gymnosperm was, from then-on, applied to seed plants with naked ovules, and the term angiosperm to seed plants with enclosed ovules. However, for many years after Brown's discovery, the primary division of the seed plants was seen as between monocots and dicots, with gymnosperms as a small subset of the dicots. [4]
As long as a non-native plant is not invasive, some can also help pollinators by providing nectar and pollen throughout the season, often filling in the gaps for the native plants.
The fruit is dry and dehiscent, when it is a capsule it shows loculicidal dehiscence. Regarding the interaction between pollen and pistil, pentapetalous plants have a gametophytic incompatibility system based on the RNAase system. [2] [8] Another anatomical characteristic of Pentapetalae is the presence of a closed root apical meristem.
