  • Resources from Plants
    • food crops, cash crops, ornamental plants, medicinal plants, compost etc.

We can use vegetables that we grow for their leaves, fruits, stems, and roots. There are different types of plant resources. These include;

a. food crops
b. crops for textiles
c. cash crops
d. wood crops
e. medicinal plants.
f. ornamental plants
g. compost and Manure

a. Food Crops:

These are resources from the environment used mainly as food. They are categorized into:

1. Leafy vegetables: As you know, we eat these, either cooked or fresh, as salads. They provide us with minerals (including calcium and iron) and vitamins (particularly Vitamins A and C) which our bodies need. Examples include lettuce, Cabbage, Talinum, etc.

2. Fruits: Examples are peppers, tomatoes, okro, mangoes, bananas, pawpaws, dates, oranges, lemons, pineapples, etc. They provide the body with mineral salts and vitamins.
