Assertion and Reason: Components of Food | Class 6: Additional Practice PDF Download

The questions below consists of an assertion and a Reason. Use the key to choose the appropriate answer.

Q1: Assertion: Obesity occurs when one takes more food than requirement.
Reason: The extra food gets stored as fat and the person becomes too fat.
(a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true but R is not the correct explanation of A.
(c) A is true but R is false.
(d) A is false but R is true.
Ans: (a)
In this case, both the assertion and the reason are true, and the reason correctly explains why the assertion is true. Obesity occurs when a person consumes more calories through food than their body requires for energy expenditure. The excess calories that are not utilized for energy are stored in the body as fat, leading to weight gain and obesity. So, the reason provided does indeed explain why obesity occurs due to overeating.

Q2: Assertion: Foods containing proteins are called body building foods.
Reason: Paneer is a plant source of protein.
(a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true but R is not the correct explanation of A.
(c) A is true but R is false.
(d) A is false but R is true.
Ans: (c)
While assertion A is generally true, the reason provided (R) is incorrect. Paneer is not a plant source of protein; it is actually a dairy product derived from milk, making it an animal source of protein. Therefore, the reason is false and does not support the assertion.

Q3: Assertion: Deficiency of calcium causes rickets.
Reason: In our diet milk and milk products are the major source of calcium.
(a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true but R is not the correct explanation of A.
(c) A is true but R is false.
(d) A is false but R is true.
Ans: (b)
Both the assertion and the reason are true. However, the reason provided is not a correct explanation for the assertion. Rickets is a condition primarily caused by a deficiency of vitamin D and not solely by a deficiency of calcium. While calcium is essential for bone health, rickets results from inadequate vitamin D, which impairs calcium absorption and leads to improper bone formation. While milk and milk products are indeed a good source of calcium, they do not directly address the deficiency of vitamin D that causes rickets.

Q4: Assertion: Dried beans and eggs contain appreciable amounts of phosphorus.
Reason: Milk and dairy products are excellent sources of phosphorus.
(a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true but R is not the correct explanation of A.
(c) A is true but R is false.
(d) A is false but R is true.
Ans: (b)
Both the assertion and the reason are true. Dried beans and eggs do contain significant amounts of phosphorus. However, the reason is not a correct explanation for the assertion. While it is true that milk and dairy products are good sources of phosphorus, the assertion is not dependent on this fact. Dried beans and eggs containing phosphorus doesn't rely on milk and dairy being sources of phosphorus.

Q5: Assertion: Carbohydrates are important components of our food.
Reason: Carbohydrates provide energy to the body.
(a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true but R is not the correct explanation of A.
(c) A is true but R is false.
(d) A is false but R is true.
Ans: (a)
Carbohydrates are indeed a crucial component of our diet. They are the body's main source of energy, which is necessary for carrying out various bodily functions and physical activities.

Q6: Assertion: Proteins are the bodybuilding food.
Reason: They help in the growth and repair of body tissues.
(a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true but R is not the correct explanation of A.
(c) A is true but R is false.
(d) A is false but R is true.
Ans: (a)
Proteins are often referred to as bodybuilding foods because they are essential for growth, development, and repair of body tissues. They are the main dietary requirement for the growth of muscles, skin, hair, nails, and other body parts.

Q7: Assertion: Deficiency of vitamin D can lead to night blindness.
Reason: Vitamin D is necessary for maintaining healthy vision.
(a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true but R is not the correct explanation of A.
(c) A is true but R is false.
(d) A is false but R is true.
Ans: (d)
The assertion is incorrect because it is Vitamin A, not Vitamin D, whose deficiency can lead to night blindness. However, the reason is correct as vitamins, in general, play a crucial role in maintaining various body functions, including vision.

Q8: Assertion: Deficiency of dietary fiber in our food can lead to constipation.
Reason: Dietary fibers add bulk to the diet and help in the digestion process.
(a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true but R is not the correct explanation of A.
(c) A is true but R is false.
(d) A is false but R is true.
Ans: (a)
Dietary fibers are non-digestible parts of our diet derived from plants. They add bulk to our diet and aid in the digestion process, preventing digestive problems like constipation.

Q9: Assertion: Water is a micronutrient essential for our body.
Reason: Water helps in the transportation of nutrients and oxygen in the body.
(a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true but R is not the correct explanation of A.
(c) A is true but R is false.
(d) A is false but R is true.
Ans: (d)
The assertion is incorrect because water is not a micronutrient. Micronutrients are vitamins and minerals that are required by the body in small amounts. Water is, however, essential for our body as it helps in the transportation of nutrients and oxygen, among other functions.
