(d) False Download Formulae Handbook For ICSE Class 9 and 10, Selina ICSE Solutions for Class 10 Biology Chapter 6 Photosynthesis: Provider of Food for All, Solution A.1. Dark reaction of photosynthesis occurs simultaneously with light reaction. This rise occurs up to the optimum temperature of 35oC (maximum suitable temperature when the photosynthesis occurs best) after which falls and stops above 40 Co. (c) If you immerse a leaf intact on the plant in ice cold water, it will continue to photosynthesize in bright sunshine. ICSE Solutions Selina ICSE Solutions ML Aggarwal Solutions. ICSE Biology Previous year Question Paper 2019 Solved for Class 10 ICSE 2019 Biology Board Question Paper Solved. The light energy is then converted into chemical energy in the form of glucose using carbon dioxide (CO2) from the atmosphere, and water (H2O) from the soil. Carbon dioxide is absorbed by producers to make glucose in photosynthesis. The leaves will not show the presence of starch. We know that the oxygen is consumed during respiration in plants hence it cannot be demonstrated at the daytime, as plants carry out respiration at night. The appearance of a blue-black colour on the leaf is indicative of the presence of starch. In a sense, even this oxygen is not a waste, because all organisms require it for their existence including the plants which require it at night. Food chain Water is taken up by the roots from the soil, sent up through the stem and finally brought to the leaves (site of photosynthesis) through the xylem tissue. (a) Dip the leaf in boiling water for a minute to kill the cells. Photosynthesis in green plants is directly and indirectly dependent on so many plant structures. (ii) Name the membrane that connects thylakoid of one granum With the other granum. Oxygen is used up and carbon dioxide is released. (e) The organisms that can be called “natural purifiers” of the air. Chloroplasts are mainly contained in the mesophyll cells. (c) Then place it again in hot water to soften it. 6. If a green plant is kept in bright light, it tends to use up all the CO2 produced during respiration, for photosynthesis. During this period, all the starch will be removed from the leaves and stored in the storage organs. (e) Draw a neat diagram of a chloroplast and label its parts. “Oxygen is a waste product of photosynthesis.” Comment. Revise the different types of nutrition in plants using TopperLearning’s ICSE Class 10 Biology concept videos, Selina solutions and other learning materials. Nervous System. 3. All plants and animals, respire by oxidizing carbohydrates in their cells to produce energy and give out carbon dioxide into the atmosphere. To register Biology Tuitions on Vedantu.com to clear your doubts. As mentioned in the above answer, the plant in test tube B has more concentration of CO2 available because the snail releases CO2 during respiration. He took a potted plant and kept in the dark for over 24 hours. Solution:-, (e) Green plants are consumers. Phloem is the tissue that transports manufactured type of starch from leaves to all parts of the plants. (c) Mesophyll cells Short Questions. 1 for their survival. d. Before starting the experiment, it is necessary to destarch the leaves of the plant by keeping the plant in complete darkness for 48 hours. Destarching is carried out so that all the starch from the leaves will be sent to the storage organs. (a) Guard cells: They regulate the opening and closing of stomata and thus regulate the entry of carbon dioxide through the stomata. Solution:-. a) continue to live, but will not be able to store food, Solution A.6. Green plants (producers) use carbon dioxide of the air to produce carbohydrates and release oxygen to the atmosphere. Which one chemical reaction occurs during photosynthesis? (a) False. (g) Photosynthesis stops at a temperature of about 35oC. Solution:-.

(g) Photosynthesis is considered as a process supporting all life on earth. A single vascular bundle, no matter how large or small, always contains both xylem and phloem tissues. (d) Calvin cycle (b) Invert a test-tube full of water over the stem of the funnel. This matter comes from dead animals and plants. One would easily think that the rate of photosynthesis will increase with light intensity. b. The glucose is converted into insoluble starch and later into soluble sugar i.e. Chlorophyll is the green colouring matter found in plants. Enumerate the steps involved in testing a green leaf for the presence of starch. they depend directly or indirectly on the producers for their food. Given below is a schematic diagram to illustrate some aspects of photosynthesis. c. Destarching ensures that any starch present after the experiment has been formed under experimental conditions. Structure Of Chlorophyll. Which four of the following are needed for photosyn-thesis in a leaf: (i) Carbon dioxide: (ii) Oxygen: … These are also found in the guard cells of stomata and in the outer layers of young green stems. b) glucose formed in photosynthesis soon gets converted into starch, Solution A.5. To demonstrate the importance of carbon dioxide in photosynthesis We know that temperature is an important factor for the rate of photosynthesis. It takes place in the presence of light. A plant used for an experiment on photosynthesis should initially be placed in the dark for 24 to 48 hours to distarch the leaves.
