Monocots & Dicots

  • Monocots consist of seeds that are a single piece-an example of which is corn, while Dicot seeds can be split into two, like in the case of peas.
Monocots:
  • Embryo with single cotyledon
  • Pollen with single furrow or pore
  • Flower parts in multiples of three
  • Major leaf veins parallel
  • Stem vascular bundles scattered
  • Roots and adventitious
  • Secondary growth absence

Examples of Monocots:

  • grass
  • cattails
  • lilies
  • onions
  • orchids

Dicots:

  • Embryo with two cotyledons
  • Pollen with three furrows or pores
  • Flower parts in multiples of four or five
  • Major leaf reticulated
  • Stem vascular bundles in a ring
  • Roots develop from radical
  • Secondary growth often present

 Examples of Dicots:

  • bean seeds
  •  peanuts
  • geranium
  • snapdragon
  • citrus

 Evolving Into Another:

Monocots(monocotyledons) where evolved within dicots(dicotyledons). Throughout the years, the evolutions of monocots have increased in size and shape which are now known as dicots.  

According to research on the evolution on DNA between monocot and dicots, the monocots evolved from dicotyledonous stock, not from the base of the tree, and monocots originated after several groups of dicotyledons had already evolved.
