Food Test - 1

Tapeworm animal eat food already digested by another animals.

All the minerals given in the option are important for our body.

Minerals are those elements on the earth and in foods that our bodies need to develop and function normally. Those essential for health include calcium, phosphorus, potassium, sodium, chloride, magnesium, iron, zinc, iodine, chromium, copper, fluoride, molybdenum, manganese, and selenium.

Hence, the correct option is (D).

Lactose is the sugar found in milk. Fat soluble vitamins are stored in the fat tissues of our body and used only when the body needs them, however water soluble vitamins are not stored in our body and need to be regularly supplied through food.

P is protein, Q is fat, R is carbohydrate and S is vitamin C. Deficiency of proteins causes kwashiorkor whereas marasmus is caused by deficiency of proteins along with carbohydrate. Marasmus occurs in children usually in infants below the age of 1 year and kwashiorkor occurs in children.

Pair of carnivores-

i. Snake

iii. Vulture

A seed contains a tiny embryo inside it that has a part called radicle which gives rise to roots and a part called plumule which gives rise to shoot system i.e. stem, leaves, etc. During sprouting, radicle comes out first. Hence, the white structures observed are roots because the seeds have sprouted. These sprouted seeds can be washed and eaten raw as a protein-rich snack.

According to the given dichotomous key P, Q, R and S could be glucose, cellulose, calcium and iron respectively. Goitre is caused by deficiency of iodine. Cellulose is complex carbohydrate occurs in the cell wall of plant cells and plant fibres.

A seed oil is a vegetable oil that is obtained from the seed of some plant. Most vegetable oils are seed oils. Some common examples are sunflower oil, canola oil, sesame oil, mustard oil, linseed oil, etc.

In coriander, Seeds, Stem and Leaves part of the plant is edible.

Statement 1 is correct- Plants are producers.

Statement 2 is incorrect- Honey is a plant product.

When we take raw egg white in a test tube and add copper sulphate solution and caustic soda to it, then after shaking, the solution in the test tube turns violet in colour. This experiment is done to test the presence of proteins in food items.

Sugarcane stores food in its stem.

X consists of sugar while Y consists of protein.

The edible portion is a rhizome (an underground stem) that is also a tuber. The "eyes" of the potato are lateral buds. Potatoes come in white, yellow, orange, or purple-colored varieties.

In most snakes, teeth are located on the dentary of the lower jaw, the maxilla, the palatine bone and the lateral pterygoid plate.

P-Broccoli; Q-Potato; R- Clove; S-Turnip

Calcium, Potassium and Sodium are macrominerals as they are needed by the body in larger amounts whereas Iodine is a trace mineral as it is needed by the body in very small amounts. Vitamins A, D and E are fat-soluble while vitamin B is water soluble. Oil is rich in unsaturated fats while cheese, butter and ghee are rich in saturated fats.

Hence, the correct option is (B).

Monkeys are omnivores. This means that they eat meat and plant-based foods. Most monkeys eat nuts, fruits, seeds and flowers. Some monkeys also eat meat in the form of bird's eggs, small lizards, insects and spiders.

Plants produce their food by the process of photosynthesis. The extra food material is stored in different parts of plants which become edible. For example, stem of potato and onion, leaves of coriander and cabbage, flower of cauliflower and broccoli and seeds of wheat and corn are the edible parts of the plant.

The banana leaves are not eaten but may be used for wrapping food in cooking. The banana foliage and pseudostems are used as cattle feed during dry periods in some banana producing areas. Layers of hard outer stem are peeled away and only the tender inner stem is used. It is very fibrous, so the thread fiber has to be cleaned. The stem is chopped into small bits and soaked in buttermilk or diluted yogurt for half hour. In Southern parts of India, it is cooked as a vegetable and eaten along with rice. The banana flower is rich in vitamins, flavonoids and proteins. The flower has been used in traditional medicine to treat bronchitis, constipation and ulcer problems. Banana fruit may be eaten raw or as a cooked vegetable. The fruit can also be processed for a number of food products.

Salt is included in our diet but it is neither a plant nor an animal product.

In the given Venn diagram X, Y and Z represent vitamin D, vitamin E and vitamin K, respectively. Deficiency of vitamin A causes night blindness and deficiency of vitamin C causes scurvy. Pellagra is caused by deficiency of vitamin B₃. Vitamin B is a group of several vitamins like B₁, B₂, B₃, B₆, B₁₂ and folic acid and is known as vitamin ; B complex.

Sprout is produced when the seeds begin to grow by developing tiny roots.

Edible oil seed crops are classified as conventional (rapeseed, mustard, sesame, groundnut), non-conventional (sunflower, safflower, soybean) and non-true oilseeds (cotton, maize and rice bran). 

Cod liver oil is a great source of omega-3 and vitamin A, both of which may protect against vision loss from inflammatory eye diseases like glaucoma and age-related macular degeneration (AMD).

In the given paragraph P, Q, R and S refer to vitamin A, vitamin D, magnesium and vitamin K, respectively. Cod liver oil is a rich source of vitamins A and D.

Kwashiorkor is caused by deficiency of protein while marasmus is caused by deficiency of protein, carbohydrate and fat.

Kwashiorkor is a deficiency disease caused by deficiency of protein in the diet. The child suffering from this disease becomes thin and weak. Skin becomes scaly and develops cracks, there is stunted growth and retarded mental development. Other symptoms of the disease include large pot like belly, swelling of feet and ankle, diarrhoea etc.

(i)- Vitamin A, (ii)- Scurvy

(iii)- Iodine, (iv)- Calcium

Wheat is the most important staple crop in temperate zones and is in increasing demand in countries undergoing urbanization and industrialization. In addition to being a major source of starch and energy, wheat also provides substantial amounts of a number of components which are essential or beneficial for health, notably protein, vitamins (notably B vitamins), dietary fiber, and phytochemicals.

All the nutrients are required by the body in specific quantities. People who do not get a balanced diet suffer from deficiency diseases. Protein deficiency causes marasmus and kwashiorkor. Deficiency of phosphorus causes weakening of bones, malfunctioning of nervous system, etc.

In Spinach plants, seed is not the edible part.

In the given flow chart, X, Y and Z refer to carbohydrate, vitamin and mineral, respectively.

Jackal is an example of a scavenger. Jackals are small canines that have adapted to hunting small mammals, birds and reptiles. Some species of jackal have even been known to eat poisonous snakes. Jackals are carnivorous mammals and jackals will often scavenge the remains of kills made by other larger predators.

We eat roots of radish, turnip, carrot and beetroot. We eat leaves of spinach, cabbage and coriander. We eat stems of potato, sugarcane and onion. However, fruit of mango and flower of broccoli are edible.

Fruits, Grasses and leaves of many plants are food substances.

Herbivores, Carnivores, Omnivores are the categories of animals divided on the basis of food habits.

'W is the modified fleshy tap root of turnip which stores the reserve food material. 'X' represents garlic i.e. an underground stem modification. In both garlic and onion, fleshy scales are edible. Y is tomato, which is a fruit but is eaten as a vegetable. 'Z' represents wheat grains, which are edible seeds but in potato stem is edible.
