Educational worksheet on food components featuring multiple choice, fill-in-the-blank, and true/false questions.

Here are the solutions to the worksheet problems, broken down step by step.

Multiple Choice Questions

1. The substance which are essential for maintaining life and growth, called _______.
* Reasoning: Our bodies need specific substances from food to stay alive, grow, and repair themselves. These substances include carbohydrates, proteins, fats, vitamins, and minerals. Collectively, these are known as nutrients. Vitamins and proteins are just types of nutrients, but "Nutrients" is the general term for all essential substances.
* Answer: (a) Nutrients

2. Which of the following is not a nutrient?
* Reasoning: Carbohydrates, fats, and vitamins are all chemical substances that provide energy or help body functions; they are nutrients. Water is essential for life, but in the context of basic nutrition classification in school science, it is often distinguished from "nutrients" because it does not provide energy (calories) or building blocks like the others do, although modern science classifies it as a nutrient. However, looking at standard curriculum options, usually, the question implies "which provides energy/builds tissue". Let's re-evaluate based on common textbook definitions. Actually, most textbooks list 6 major nutrients: Carbohydrates, Fats, Proteins, Vitamins, Minerals, and Water. Is there a trick? Let's look closer. Wait, usually, roughage (fiber) is considered non-nutritive in older texts, but it's not an option here. Let's look at the options again: (a) Carbohydrates, (b) Fats, (c) Water, (d) Vitamins. In many primary science contexts, water is sometimes treated separately from "food components" that give energy or build body parts. However, strictly speaking, all are nutrients. Let's look for a better interpretation. Perhaps the question is flawed or relies on a specific definition where water is a "medium" rather than a nutrient. *Correction*: In many elementary science books, the main "components of food" listed are Carbohydrates, Fats, Proteins, Vitamins, Minerals, Roughage, and Water. Among the choices, Carbohydrates, Fats, and Vitamins are complex organic compounds. Water is inorganic. Often, questions like this might consider Water as the outlier because it doesn't provide energy or build tissue in the same way. Let's stick with (c) Water as the likely intended answer in this specific educational context, as it is distinct from the organic energy-providing or regulatory nutrients.

*Self-Correction/Refinement:* Actually, let's look at Question 3 and 4. They are straightforward. Question 2 is tricky. Let's assume the standard definition: Nutrients provide energy or help growth. Water helps transport but doesn't provide energy. So (c) is the best fit among the choices for "not a nutrient" in the sense of "energy-giving or body-building substance".

* Answer: (c) Water

3. Ghee and butter are also called _______.
* Reasoning: Ghee and butter are made from milk, which comes from animals (cows, buffaloes, etc.). Fats obtained from animals are called animal fats. Vegetable fats come from plants (like oilseeds).
* Answer: (b) Animal fat

4. Which of the following are good sources of plant proteins?
* Reasoning: Fish, Milk, and Eggs are all products that come from animals. Nuts (like almonds, walnuts, peanuts) grow on trees or plants and are rich in protein. Therefore, nuts are the source of plant protein here.
* Answer: (a) Nuts

5. Which of the following nutrients helps us to fight diseases?
* Reasoning: Carbohydrates and proteins provide energy and build the body. Roughage helps digestion. Vitamins and minerals protect our body against various diseases and keep us healthy. For example, Vitamin C helps fight infections.
* Answer: (c) Vitamins

Fill in the Blanks

1. Mango contains _______ carbohydrate.
* Reasoning: Fruits like mangoes contain natural sugars. Sugar is a simple type of carbohydrate.
* Answer: sugar

2. Minerals are extracted from the _______.
* Reasoning: Plants absorb minerals from the soil through their roots. When we eat plants, we get those minerals.
* Answer: soil

3. For proper _______ and _______ of our body, we need adequate food.
* Reasoning: Food is needed for two main reasons: to help the body grow (increase in size/height) and to maintain health/repair tissues. The standard phrase is "growth and maintenance" or "growth and development". Given the context of "maintaining life" in Q1, "maintenance" fits well. Another common pair is "growth and health". Let's go with the most scientific standard for this level: growth and development (or maintenance). Let's use growth and maintenance as it pairs with the first question's logic.
* Answer: growth, maintenance

True or False

1. An oily patch on paper shows that food item contains fat.
* Reasoning: This is a standard test for fat. If you rub a food item on paper and it leaves a translucent (shiny/oily) spot that doesn't dry up quickly, it indicates the presence of fat.
* Answer: True

2. Foods containing proteins are often called energy-giving foods.
* Reasoning: This is false. Carbohydrates and fats are primarily called "energy-giving foods" because they provide fuel for the body. Proteins are called "body-building foods" because they help in growth and repair of tissues. While proteins *can* provide energy, their main label in school science is body-building.
* Answer: False
