Question Discussion & Solution

The correct answer is Sesamum.

Key Points

• Seasame is a Rabi crop in South India.
• It is a flowering plant in the genus Sesamum and in India, it is smaller in numbers.
• Another species of Sesamum is S. Indicum.
• Sesamum is also known as Benne.
• The mustard plant is a plant species in the genera Brassica and Sinapis in the family Brassicaceae.​

Additional Information

• Finger millet (Ragi)
  • Millet is a collective term referring to a number of small-seeded annual grasses that are cultivated as grain crops, primarily on marginal lands in dry areas in temperate, subtropical, and tropical regions.
  • Some of the common millets available in India are Ragi (Finger millet), Jowar (Sorghum), Sama (Little millet), Bajra (Pearl millet), and Variga (Proso millet).
• Barley
  • Barley is cultivated as a rabi season crop in Rajasthan.
  • It is sown in October-December and harvested from March to May.
• Wheat
  • It is a Rabi crop generally sown between October & November harvested between April & May.

Concept:

• Food comprises constituents like proteins, carbohydrates, fats and supplementary substances such as minerals, vitamins and water that are vital for life.
• These constituents are known as nutrients. For proper functioning of our body, we need to consume bodybuilding foods (e.g. milk, meat, poultry, fish, eggs, pulses, groundnuts); energy-giving foods (e.g. cereals, sugar, roots, fats and oils); and protective foods (e.g. vegetables, fruits).

Explanation:

• Carbohydrates are the main source of energy for our body.
• Carbohydrates are of two types – simple and complex.
• Simple carbohydrates - These are quick-energy foods, e.g. sugar. Sources of simple carbohydrates are natural fruits, milk and milk products, and vegetables including potatoes and carrots.
• Complex carbohydrates - These are better sources of energy than sugar since they are released slowly. Sources of complex carbohydrates are bread, cereals (rice, wheat, bajra, corn, barley, ragi, sorghum, millets etc.),

Gram is not a source of carbohydrate, it is a source of protein.

Additional Information

Proteins:

• proteins are obtained from the animal as well as vegetable sources. Proteins of animal origin are found in milk, eggs, cheese, fish and meat.
• Proteins from these sources contain all the essential amino acids (EAA) in adequate amounts.
• Vegetable proteins are found in pulses (legumes), cereals, beans, nuts, oilseeds, etc

The correct answer is Cell.

Key Points

• Cell:
  • A cell is the smallest unit capable of independent existence which can reproduce itself. Hence, Option 3 is correct.
  • All living organisms, except for viruses, are composed of one or more cells.
  • Single-cell organisms; such as, bacteria, protozoa, and other micro-organisms are termed unicellular, while plants and animals that contain many cells are termed multicellular.
  • Highly complex organisms; such as, human beings consist of billions of cells, all of which are adapted to carry out specific functions; for example, groups of these specialized cells are organized into tissue and bodily organs.
  • Although cells may differ widely in size, appearance, and function, their essential features are similar.

​

Important Points

• Almost all cells perform biochemical processes, generate and process energy, and store genetic information to be passed down to future generations of cells.
• Advanced single-celled and multicelled organisms have nuclei that carry the DNA, primitive cells; such as, bacteria, have no nucleus and carry their DNA loosely in coils throughout the cells
• The number of cells in an organism varies; for example, bacteria are single-celled organisms; the average adult human body has about one hundred trillion cells.
• Cells are the structural unit of all organisms and come in a range of sizes and shapes.
• Animal cells contain only an outside cell membrane.
• In most fungi, bacteria, and plants; there is a rigid cell wall outside the membrane.
• Each cell is composed of a mass of jelly-like substance called the cytoplasm, surrounded by a membrane.
