i. Monocotyledon and Dicotyledon plants

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

(i) List five crops that are monocotyledons and five crops that are dicotyledous.

Presentation

The topic is presented step by step

 

Step 1:

The class teacher revises the previous topics

 

Step 2.

He introduces the new topic

 

Step 3:

The class teacher also goes round to make sure that the notes are well copied or well written. He or she does the necessary corrections when the need arises.

 

Assignment :

Prepare for the next lesson by reading about

 

ASSIGNMENT

Each student to draw a germinating seedling of maize and cowpea to show hypogeal and epigeal germination.

WEEKEND ASSIGNMENT

Plant maize and groundnut seeds and observe them after germination and classify them into monocotyledons and dicotyledons.
