The dicots are thought to be older group of plants from which the monocots have evolved. Thus, monocots are thought to be evolved later than dicots.

The simpler anatomy of the monocots is thought to be more efficient in utilising the solar energy and grow rapidly.

The monocots have the higher ability to withstand damage due to grazing, burning and disease than most of the dicots.

The monocots have only one cotyledon while as dicots have two cotyledons. Thus, monocot embryo gets everything from a single source i.e one cotyledon. The dicot embryo uses more resources to create second cotyledon, thus making it less efficient than the monocot.

Monocots are considered more advanced than dicots because they have some special features that help them grow better in different environments. For example:

1. Fibrous roots – Monocots have fibrous root systems which spread out wide and help them absorb more water and nutrients from the soil quickly.

2. Parallel venation – Their leaves have parallel veins which make them strong and better at handling sunlight.

3. Adaptability – Most grasses, like rice, wheat, and corn (which are monocots), grow faster and can survive in different climates, making them more useful for humans.

4. Efficient seed structure – Monocot seeds have one cotyledon, and they store food in a different way (endosperm), which helps them germinate faster.
