6 life processes

Flashcards. RBCs are produced at the foetal stage by the liver. (d) None of these, 5. (c) pseudopodia These are only found in the mammals. What is A.T.P.? (b) whale, dolphin, turtle Answer: RBCs present in blood have haemoglobin which bind with O2 and form oxyhaemoglobin. When temperature decreases, decrease in transpiration takes place. Let us learn about all of these briefly. (d) Chloroplast, 15. Modes … Answer: The duodenum, receives secretions of two glands, i.e., liver and pancreas. Answer: It mixes with saliva and the enzyme amylase (found in saliva) breaks down starch into sugars. (a) Cytoplasm Intercostal muscles are found in between the ribs. (iii) Absorption: Now, the food enters from duodenum into ileum part of small intesntine where millions of finger-like projections known as villi are present which absorb the food. Save my name, email, and website in this browser for the next time I comment. The blood has ………. Answer: Question 11. Animals, on the other hand, need energy for different activities like movement or search of food. In which mode of nutrition an organism de-rives its food from the body of another living organism without killing it? (b) transpiration Question 44. Answer: Now, the partially digested food enters from stomach into the small intestine’s wider part which is known as duodenum and the remaining part of the small intestine is termed as ileum. These valves are attached with fine cords with the papillary muscles of the ventricular wall. Explain the mechanism of gaseous exchange between tissues and blood. Name the correct substrates for the following enzymes: Question 17. The release of water vapours in the atmosphere through the pores present on plant leaves, i.e., stomata, is called transpiration. Its opening is also guarded by a valve, having 3 semilunar flaps. LIFE PROCESSES 93 CHAPTER 6 In Glycolysis, glucose (a simple carbohydrate) is split into two molecules of pyruvic acid. Therefore, it (required as a raw material for photosynthesis) cannot enter into the leaves and thus lack of water slows down the rate of photosynthesis. (See Fast Track Revision): Out of these lights of different wavelengths, chlorophyll absorbs mainly blue, violet, red and orange lights but does not absorb the green light. Show them with the help of a labelled diagrams. (b) mitochondria Question 27. Question 14. Question 37. Answer: Liver. Nutrients: Those substances which supply nourishment to living organisms from its surroundings and use it as an energy source or for biosynthesis of body constituents. (c) Kidney → ureter → urethra → urinary bladder (b) filtration Answer: (a) food vacuole Usually, in oesophagus there is no digestion of food. (i) Humidity: There is an increase in transpiration when atmospheric humidity decreases, while transpiration decreases with increase in humidity. The valve separating left atrium from left ventricle is called left atrio-ventricular valve or mitral valve, formed of two flaps. Question 20. For respiration, in older roots, where root hair is not present, the exchange of gases takes place through lenticels (tiny openings in the protective layer) by the process of diffusion. i) Nutrition:– is the process of taking food by an organism and its utilization by the body for life processes. The ammonia is produced as a result of metabolism of amino acids. 7. platelet (b) RBC (i) Ingestion: Amoeba ingests food with the help of its finger-like extensions, called pseudopodia. Question 8. Answer: Life Processes Class 10 Notes Biology . (c) starch Each living thing can Move, Reproduce itself and is Sensitive to the world around it. The breakdown of pyruvate to give carbon di-oxide, water and energy takes place in (a) Glycolysis: The conversion of glucose into pyruvate (or pyruvic acid) is called glycolysis. (ii) CO2 moves out of the blood? Life Processes Class 10 Extra Questions with Answers Science Chapter 6 October 15, 2020 September 24, 2020 by Laxmi In this page, you can find CBSE Class 10 Science Chapter 6 Extra Questions and Answers Life Processes Pdf free download, NCERT Extra Questions for Class 10 Science will make your practice complete. Question 43. The blood reaching the tissues has higher concentration of oxygen than in the cells so it gets diffused into the cells. Answer: Question and Answer forum for K12 Students. . Question 24. Twinkl's selection of resources about Life Processes and Living Things can help you to teach KS2 children about the lives of plants and animals. A → Stomatal pore (i) Describe aerobic respiration. (a) fats (c) Xylem (d) simple proteins, 11. This type of respiration occurs in microscopic organisms like yeast, etc. (a) Urethra Question 38. “All plants give out oxygen during day and carbon dioxide during night”. The swelling of guard cells due to absorption of water causes opening of stomatal pores while shrinking of guard cells closes the pores. Difference between Respiration and Combustion. Name the energy currency in the living organisms. (d) Fats breaking down into fatty acids and glycerol. → All living things perform certain life processes like growth, excretion, respiration, circulation etc. In this chapter we introduce the methods by which chemical tracers have been used to determine biological fluxes. Plant kept in continuous light will live longer. The ammonia combines with CO. The exit of unabsorbed food material is regu-lated by Thus, due to transpiration water is pulled upward which creates an upward suction force called ‘transpiration pull’. (d) Collenchyma, 19. Salivary amylase. (i) The respiration which needs oxygen or occurs in the presence of oxygen is called aerobic respiration. It is a type of nutrition in which inorganic materials such as carbon-dioxide, is used up to synthesize organic food by a process known as photosynthesis. Question 29. Question 4. Small intestine Green plants and some bacteria. (iv) Assimilation: The blood carries the digested and dissolved food to all parts of the body, where it is assimilated into the cells which is used for obtaining energy as well as for growth and repair of the body.
