     ii. Difference between monocotyledon and Dicotyledon plants
Sub – Topic 1: Monocotyledon and Dicotyledonous.
Monocotyledons plants: These are plants with one seed leaf or Cotyledons e.g. maize, rice, oil palm, coconut, wheat, millet, banana etc.
Dicotyledonous plants: These are plants with two seed leaves or cotyledons e.g. cowpea, mango, citrus, cashew groundnuts, tomatoes, kola, mango etc.
EVALUATION
