Photosynthesis in Plants

Aim: To investigate the effect of divers(prenominal) light intensities on the rank of photosynthesis (conventional method) Introduction: Photosynthesis is the main process by which plants elevate food. There argon a few conditions required for photosynthesis to withdraw place. They are: Chlorophyll, Light, vitamin C paper Dioxide and Water. Each of these factors has a different effect on the browse of photosynthesis. In plants, the chlorophyll pitch in the chloroplasts, converts the light heartiness from the sun and converts it into chemical energy. It to a fault traps the suns light energy. Hence, the light is obtained from the sun, but an artificial source, e.g.: light medulla can be used. When carbon dioxide and water system react in the presence of chlorophyll and light, photosynthesis in plants takes place to give glucose and oxygen. The reply is: Light energy 6CO2 + 6H2O C6H12O6 + 6O2 The carbon dioxide is taken in by the plants during the da y when the stomata are open and water is confined by the roots of the plants from the soil. To measure the rate of photosynthesis, all the preceding(prenominal) factors mentioned are necessary. up to now if one of them is absent, then photosynthesis will non take place. Hypothesis: As the light intensity increases, the rate of aglitter(p) will increase as well Apparatus: * Water plant (e.g.: Cabomba, hydrilla or Elodea) * Dilute sodium hydrogen carbonate solution * digital Thermometer * Test Tube * Beaker * 2 Retort Stands * Bulb (60 W) * metre Rule Method: * abbreviate a piece of water plant about 5cm long * fix up the apparatus as seen in the figure beneath with the cut abolish of the plant facing upwards. You might read to tie a small weight, e.g.: stone to the plant to abide by it submerged in the water * Place a bulb of 60...
