Monocot

Supplement
Examples of monocotyledonous plants are the palms, grasses, orchids, and lilies.
The angiosperms (the flowering plants) can either be a monocotyledon (or monocot) or a dicotyledon (or dicot) according to the number of cotyledons in their seeds.
Apart from the number of cotyledons, other identifying characteristics are as follows:

  • the number of flower parts – monocot flowers are trimerous (in multiples of three)
  • the number of pores in pollen – monocots have one
  • arrangement of vascular bundles in the stem – in monocots, the vascular bundles are scattered
  • the roots – monocot roots are adventitious roots
  • the arrangement of major leaf veins – in monocots, the leaves have parallel venation.

Word origin: From mono- (“one”) + cot- abbreviated form of cotyledon (“embryonic leaf”).
