Questions Based on High Order Thinking Skills (HOTS)
51. The green plants make their own food by the process A by combining water (and nutrients like nitrogen), carbon dioxide gas and energy.
What is the name of process A?
From where do the green plants get carbon dioxide for making food?
From where do green plants get energy for making food?
What name is given to green plants which make their own food?
The atmospheric carbon dioxide molecules are fixed in the dark reaction during photosynthesis, and glucose molecules are produced. Water and oxygen are byproducts of photosynthesis. During photosynthesis, chlorophyll molecules trap sunlight and convert it into chemical energy. 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.
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.
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.
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.
What could the seeds X and Y be?
What is the general name of Z?
What are the tiny white structures in Z which grow out of the seeds?
In what way Z is a more nutritious food than X and Y?
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.
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.
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.
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.
What is organism A? Give one example of A.
Name the organism B. Give one example of B.
What are organisms like C called? Give one example of C.
What is the general name of organisms like D? Give one example of D.
Name the process E.
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).
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.
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.
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.
