To show chlorophyll is essential for photosyntesis with diagram |
| Answer» o demonstrate that chlorophyll is essential for photosynthesis.Requirements : A potted plant with variegated leaves - for example, Croton or money plant (variegated leaves are partly green and partly white), rice paper, pencil, white paper sheath, beaker, test tube, 70% alcohol, KL solution, water bath.Method : Keep the potted plant with variegated leaves in dark for three days so that the leaves become free from starch. Then place the plant in bright sun light for about 6 hours. Take a variegated leaf of the potted plant kept in bright sunlight. Trace the outline of leaves and its variegated parts on the tracing paper (the variegated leaves show pale yellow spots in green leaves. These areas indicate the absence of chlorophyll). Dip the leaf in boiling water for a few minute. Now boil the leaf in 70% alcohol till it decolorizes. Now dip the leaf in boiled water to make the leaf soft. Take out the leaf and stain with iodine (KL) solution. Observe the change in colour.Observation : The blue colour appears only in those parts of leaf which were green in colour. The blue colour will not appear in variegated parts. This shows that starch formation takes place only in green (chlorophyll containing) parts of the leaf. Thus, the chlorophyll is essential for photosynthesis.Read more on Brainly.in - https://brainly.in/question/9142768#readmore | |

Whah is redox reaction |
|
Answer» Redox reaction is the combination of oxidation and reduction A reaction in which one reactant undergoes oxidation whereas the other gets reduced during the course of reaction are termed as oxidation-reduction reactions or redox reactions. Oxidation refers to the loss of electrons or increase in oxidation state by a molecule, atom, or ion. Reduction refers to the gain of electrons or decrease in oxidation state by a molecule, atom, or ion.Consider the following redox reaction.\tBurning sugars, such as glucose (C6H12O6) and the fatty acids in the fats we eat.\tC6H12O6(aq) + 6 O2(g) --> 6 CO2(g) + 6 H2O(l)\t These reactions involve the oxidation and reduction reaction is called redox reaction |

If peepal tree only enhale and exhale oxygen so what is it\'s machanisim for making it\'s food??? |
| Answer» The process of photosynthesis takes place in the green leaves of a plant. The carbon dioxide gas required for making food is taken by the plant leaves from the air which enters the leaves through tiny pores called stomata. Water required for making food is taken from the soil which is transported to the leaves from the soil through the roots and the stem. The sunlight provides energy required to carry out the chemical reactions involved in the preparation of food. The green pigment called chlorophyll absorbs sunlight energy.\xa0 | |

Explain formation of biogas in detail |
| Answer» Biogas is a mixture of methane, carbon dioxide, hydrogen and hydrogen sulphide. The major constituent of biogas is methane.Biogas is produced by the anaerobic degradation of animal wastes like cow-dung or plant wastes in the presence of water.The biogas plant has a dome-like structure built with bricks. A slurry of cow-dung and water is made in the mixing tank from where it is fed into the digester. The digester is a sealed chamber in which there is no oxygen. Anaerobic micro-organisms that do not require oxygen decompose or break down complexcompounds of the cow-dung slurry. It takes a few days for the decomposition process to be complete and generate gases. The biogas is stored in the gas tank above the digester from which they are drawn through pipes for use. | |
