What is the Difference Between Eudicots and Monocots?

🆚 Go to Comparative Table 🆚

The main difference between eudicots and monocots lies in the number of seed leaves (cotyledons) in their seeds. Monocots, also known as "monocotyledons," produce seeds with a single cotyledon, while eudicots, also known as "eudicotyledons" or "dicots," produce seeds with two cotyledons. Some other differences between these two groups include:

  • Flower parts: Monocots have floral parts in multiples of three (3-merous), while eudicots have floral parts in multiples of four or five (4-merous or 5-merous).
  • Leaf venation: Monocots have parallel venation in their leaves, while eudicots have netted venation.
  • Vascular bundles: Monocots have vascular bundles dispersed throughout the stem in concentric circles, while eudicots have a ring of vascular bundles in their stems.
  • Secondary growth: Monocots do not have true secondary growth, although some, such as bamboo, form tough, woody stems. Eudicots, on the other hand, can have true secondary growth.

Monocots include plants such as grasses, palms, orchids, yams, sweet potatoes, lilies, onion, asparagus, bananas, and bamboo. Eudicots include plants such as roses, sunflowers, tomatoes, peas, soybeans, oaks, and petunias.

Comparative Table: Eudicots vs Monocots

Eudicots and monocots are two major groups of flowering plants, each exhibiting unique characteristics. Here is a table highlighting the key differences between them:

Characteristic Monocots Eudicots
Number of cotyledons 1 2
Floral parts symmetry 3-merous 4-merous or 5-merous
Leaf venation Parallel Net-like or reticulate
Vascular tissue Scattered Ring-like
Pollen structure Monosulcate Trisulcate or triporate

Monocots, such as grasses, rice, and corn, typically have only one cotyledon and floral parts in sets of three. Their leaf venation is parallel, and their vascular tissue is scattered in the stem. Monocots produce monosulcate pollen.

Eudicots, also known as true dicots, have two cotyledons and floral parts that come in four, five, or many whorls. Their leaf veins form a network, and vascular tissue forms a ring in the stem. Eudicots produce trisulcate or triporate pollen, with three furrows or pores. This group comprises about two-thirds of all flowering plants and includes a wide variety of species, such as roses, sunflowers, and oaks.
