Sign In Question: Monocot flowers and dicot flowers differ in
🔑Key Points:
Perfect flowers (those that contain both male and female reproductive structures) in the plant world fall into one of two categories: monocots or dicots.
Number of Cotyledons: The fundamental difference between monocot and dicot flowers concerns the number of cotyledons (seed leaves) in the plant embryo: monocots have one, while dicots have two.
Floral Parts: Monocots typically have flower parts in multiples of three (3, 6, 9, and so on), while dicots usually have flower parts in multiples of four or five.
Nectaries:Â Monocot flowers often lack nectaries, the structures that produce nectar in many flowering plants. This is not always the case, however – certain monocots do have nectaries.
Vascular Tissue:Â Vascular tissue in monocot stems is scattered randomly, while in dicots it is organized in a ring.
Root System:Â Monocots usually possess a fibrous root system, whereas dicots typically have a singular main root known as a taproot with many minor lateral roots branching off from it.
Leaf Venation:Â Monocot leaves usually show parallel venation (the veins run alongside each other from the base to the leaf apex), while dicots exhibit net or reticulate venation (the veins branch and rebranch within the blade).
Pollen Grains:Â The pollen grains of monocots have one furrow or pore, so they are monosulcate. On the other hand, the pollen grains of dicots mostly have three pores or furrows and are thus tricolpate.
