Plant Food Sources:

We get vegetables from plants that we eat daily as a part of our normal diet. The term ‘vegetables’ commonly refers to all the plant parts that humans consume.

Vegetables:

The vegetables that we eat can be broadly divided into—

• Underground (edible) vegetables.
• Above the ground vegetative parts.
• Above the ground reproductive parts.

1. Underground Vegetables:

• • These include underground stems (tubers), underground bulbs (modified short stems), and roots.

• As the parts are underground, they are mostly earthy in colour and hard in nature.

Example: Tubers—Potato, sweet potato, ginger, artichokes; Bulbs— Garlic, onion; Roots— Beet, radish, carrot, turnip.

2.  Above the ground vegetative parts:

3. Above the ground reproductive parts:

 

Types of Spices:

• These are essentially the fruits, seeds, roots, barks, or any other plant parts or substances, which give flavour and colour to the food upon adding to the cooking.
• Spices are usually dried plant parts.

• Following is a list of some of the spices and their available forms for cooking.

 

Cereals and Pulses:

• The edible seeds of legumes are called pulses.

         Example: Peas, beans, and lentils.

• The food made from pulses like peas, beans, and lentils makes our body stronger and healthy.
• Cereals yield starchy grains that are consumed as food.

         Example: Rice, wheat, maize, jowar, barley, etc.

• Cereals are also used as animal food for domestic animals like poultry, cattle, etc.
• The food prepared from cereals provides energy to our bodies.
• Roti, bread, papad, bhakri, etc., are prepared using flours made from cereals.
• The combination of cereal and pulses is a complete meal in itself.

         Example: Rajma-chawal, khichdi, pongal, dosa and roti-dal.

 

 

Medicinal Plants and Their Uses:

• Leaves, stems, roots, flowers, etc., of many plants, have medicinal properties and are used to treat some common ailments.
• Many medicinal plants are easily available around our surroundings.

         Example: Lemon is good for stomach problems, and lemon with ginger is used to cure a common cold, cough, and sore throat also. Other medicinal plants are basil (Tulsi), clove, aloe vera, etc.

 

Food From Animals:

Plants are not the only source of food that we eat. We rear some animals for food, which is called animal husbandry.

Example: Hen, lambs, pigs, goats, fish, etc.

• People living in coastal areas and near rivers consume fish and other sea foods like prawns, crabs, and shellfish.
• Different animals are reared for their eggs, milk, meat, and other products like honey, wax, wool etc.

The following list shows the animals and what food is obtained from them -
