During the light reaction, glucose is converted into fructose and glucose and fructose molecules from sucrose and starch molecules. These sucrose molecules are carried by the phloem to non-green parts of the body for use and storage. Photosynthesis is the process denoted by A in the question.

  2. The earth differs from all other planets in that it has an atmosphere in which living organisms can breathe molecular oxygen. This enables life on Earth to flourish. Plants also synthesise food, which traps solar energy as chemical energy. They use this chemical energy to convert carbon dioxide from the air into six simple sugars containing carbon. This sugar provides energy to all non-photosynthetic organisms. That is, the atmosphere is a source of carbon dioxide from green plants, which is required for food synthesis.

  3. Photosynthesis is the process by which green plants convert solar energy into chemical energy. The chlorophyll in the plant's leaves absorbs light energy. To convert carbon dioxide and water into glucose and oxygen, solar energy is required. The sunlight provides energy for green plants to produce food.

  4. Photosynthesis is indeed the process by which green plants produce their own food. Sunlight provides the energy needed to produce food. Green plants use photosynthesis to create food by absorbing water and nutrients from the soil, carbon dioxide from the air, and energy from the sun. Because plants can produce their own food, they are referred to as food producers or producers.

52. The seeds of X or Y are put in a vessel containing water and kept overnight. The seeds are then removed from water, wrapped in a piece of wet cloth and kept aside for one day. Water is sprinkled on the piece of cloth from time to time. On opening the wrap, it is found that the seeds are converted into Z having tiny white structures.

  1. What could the seeds X and Y be?

  2. What is the general name of Z?

  3. What are the tiny white structures in Z which grow out of the seeds?

  4. In what way Z is a more nutritious food than X and Y?

Ans: 

  1. There are some seeds that begin to germinate when kept in water. Tiny roots developed from the seeds are called sprouts. Chana and moong are converted into sprouts in our homes to make snacks. So, the seeds X and Y could be chana and moong.

  2. There are a few plants that store food in their seeds. Whenever these seeds are kept in water overnight and then in a wet cloth, tiny white structures have grown out of the seeds. Such seeds with tiny roots are called sprouts. So, the general name of Z is sprout.

  3. When the seeds germinate, they begin to develop roots. Germination takes place when seeds are kept in water or soil. There are a few seeds that germinate in water to form a nutritious structure called sprouts. The tiny white structures in Z that grow out of the seeds are roots.

  4. Sprouts have been formed when seeds begin to grow or germinate by developing white-coloured tiny roots on them. Sprouting is indeed the process of growing sprouts from seeds. More vitamins are found in sprout Z, which has tiny white structures. Z is more nutritious than X and Y in this case because it contains more vitamins A, B, and C.

53. A, B, C and D are all living organisms. A, B and C need ready made food whereas D can make its own food by a natural process E. The organism A can eat B as well as D. The organism B eats only D or its products whereas organism C eats only organisms like B.

  1. What is organism A? Give one example of A.

  2. Name the organism B. Give one example of B.

  3. What are organisms like C called? Give one example of C.

  4. What is the general name of organisms like D? Give one example of D.

  5. Name the process E.

Ans: 

  1. Organism A requires ready-to-eat food. It is capable of producing its own food. Other organisms can consume it as well. So, A is omnivorous. Man (Human being) is an example of an omnivore because he consumes both plant food (pulses, vegetables, and fruits) and animal meat (chicken, fish).

  2. Organism B requires ready-to-eat food. It cannot produce its own food. Other organisms can consume it as well. B is thus a herbivore. A goat is an example of a herbivore because it only eats plants or plant products such as grains for food.

  3. Organism C requires ready-to-eat food. It cannot produce its own food. It can also consume other organisms. C is thus a carnivore. The lion is an example of a carnivore because it only eats the flesh of other animals such as deer and rabbits.

  4. organism D does not require prepared food. It produces its own food through photosynthesis. It is also attained by other organisms. D is thus a producer. Food producers are plants that produce their own food through photosynthesis. 

  5. Photosynthesis is indeed the process by which green plants convert the sun's solar energy into chemical energy. The chlorophyll in the plant's leaves absorbs light energy. To convert carbon dioxide and water into glucose and oxygen, solar energy is required. Photosynthesis is the name given to the process E.

54. Food material X is a syrup-like, thick and sweet liquid which is made by a kind of insects by collecting nectar from flowers. On the other hand, food material Y is a thin liquid which can be converted into yogurt.

  1. What do you think is food X?

  2. Name the insects which make food X.

  3. Name the food Y.

  4. Name two animals which provide us food Y.

Ans: 

  1. Honeybees forage among the flowers, collecting nectar. This sweet secretion of a flower's nectar glands is converted into honey by an enzymatic reaction inside the bees' stomach. When they return to the honeycomb, they vomit this fluid into the wax-sealed compartments. Honey is mostly composed of water, carbohydrates, proteins, vitamins, and minerals. We eat honey, use it to sweeten food, and use it as medicine. Honey is the food X mentioned in the question.

  2. Honeybees are insects that produce honey. Honey is a combination of flower nectar, pollen, and enzymes. It has a high concentration of sucrose, fructose, vitamins, and minerals. Honeybees forage around flowers to collect nectar. Enzymatic reactions inside their stomach convert this nectar into honey. The food referred to as X is honey, which is produced by honeybees.

  3. Lactose, a disaccharide composed of glucose and galactose, is found in milk. Lactobacillus spp., lactic acid bacteria, convert it to lactic acid. This acid production curdles milk and yoghurt production. Yogurt contains a lot of vitamins, minerals, and proteins. Yogurt aids digestion by increasing the number of intestinal bacterial flora. Milk is the food mentioned in the given question as Y.

  4. New mothers secrete milk from their mammary glands. The sole purpose of this liquid is to nourish the newborn. As a result, milk contains all of the major food groups, including carbohydrates, proteins, fats, vitamins, and minerals. The two animals that provide us with food Y, milk, are the cow and the goat.

55. P and Q are two plants. The flowers of plant P are eaten as a vegetable whereas its fruit is a nutritious food. On the other hand the leaves of plant Q are eaten as a vegetable whereas its seeds provide an edible oil which is used as a cooking oil in the preparation of food. Name the plants P and Q.

Ans: The banana flower is consumed as a vegetable throughout India. Banana flower is used to make delectable curries and fritters. The banana's underground stem is also consumed as a vegetable. The banana fruit contains carbohydrates, proteins, vitamins, minerals, and other nutrients. It provides the body with instant energy. The mustard plant's leaves and young stems are eaten as a vegetable. It is used to make curries and fritters. P is a banana plant, and Q is a mustard plant.
