tell a activity to show that sunlight is nessecary for photosynthesis
Answers
Explanation:
Objective:
To show experimentally that light is essential for photosynthesis.
Apparatus and materials required:
A healthy potted plant, a petri dish, a beaker containing water, forceps, a water bath, a piece of wire gauze, a tripod, a burner, a box of matches, alcohol a strip of black paper, iodine solution and clips.
Theory:
Photosynthesis is a biochemical process by which green plants s5mthesize simple sugar in the presence of sunlight using carbon dioxide from the atmosphere and water from the soil. This simple sugar (glucose) is later converted to starch.
6CO2 + 12H2O ChlorophyII / Sunlight C6H12O6 + 6H2O + 6O2
The most important factor for photosynthesis is light. The rate of photosynthesis depends on the quantity and quality of light. The chlorophyll molecule in green leaves absorb light, get excited and emit electrons. The emitted electrons are used in the production of adenosine triphosphate (ATP). Finally the solar energy is converted into chemical energy and stored in the glucose produced.
