Monocots and dicots are the two broad groups of flowering plants (Division Magnoliophyta). While it is generally easy to distinguish most dicots and monocots from one another, the basis for the split in classification is a characteristic of the developing embryo, a feature that is no longer observable on the adult plant unless one can access the internal structure of a seed. Therefore, the following characteristics can be applied in the absence of knowledge about the cotyledon. However, be mindful that no 'single' characteristic will absolutely distinguish a dicot from a monocot, other than by definition monocots have one cotyledon and dicots have two. In general, monocots are simpler in structure than dicots, although monocots evolved from dicots.

The process of growing monocts and dicots alternatively is called intercropping.

Intercropping is the cultivation of two or more crops simultaneously on the same field. It also means the growing of two or more crops on the same field with the planting of the second crop after the first one has completed its development. The rationale behind intercropping is that the different crops planted are unlikely to share the same insect pests and diseased-causing pathogens and to conserve the soil.

Advantages
Reduces the insect or mite pest populations because of the diversity of the crops grown. When other crops are present in the field the insect or mite pests are confused and they need more time to look for their favorite plants.
Reduces the plant diseases. The distance between plants of the same species is increased because other crops (belonging to a different family group) are planted in between.
Reduces hillside erosion and protects topsoil especially the contour strip cropping.
Attracts more beneficial insects especially when flowering crops are included the the cropping system
Minimizes labor cost on the control of weeds. A mixture of various crops gives often a better coverage of the soil leaving less space for the development of weeds.
Utilizes the farm area more efficiently.
Results in potential increase for total production and farm profitability than when the same crops are grown separately.
Provides 2 or more different food crops for the farm family in one cropping season.
