INVESTIGATE AN ISSUE AFFECTING THE
CHARGE OF THE NATURAL PHOTOSYNTHESIS.
Photosynthesis is actually a chemical reaction which takes place in the green crops (plants with chlorophyll, a pigment present in chloroplasts which in turn causes the colour with the plants and it is the main photosynthetic pigment) and light energy is definitely converted into chemical substance energy. Carbon dioxide, water and sunlight is transformed into glucose an air, which later on will be used because energy to get the plant. The chemical formula of photosynthesis is:
Photosynthesis occurs principally inside the leaves it will be divide into two phases: the sunshine dependent reactions and light 3rd party reactions. Whenever we talk about the rate of photosynthesis we refer of how quickly photosynthesis takes place. This rate can be affected by three primary factors: temperatures, the quantity of Carbon Dioxide or the lumination intensity. Study question: How can the light depth affect the charge of the natural photosynthesis? Hypothesis: while the light power increases the charge of the natural photosynthesis will increase considering that the light based mostly reactions can produce quicker, but at certain stage the rate can become stable, with out more increasing, because of various other limiting factors needed inside the reaction while temperature or CO_2. Variables:
Independent changing: light intensity.
Dependent changing: rate of photosynthesis.
Controlled variables: heat, Carbon Dioxide, volume of water inside the beakers, distance between the beakers and the mild each time, the size of the part of elodea.
Thin and long beaker and one more shorter (just a couple of centimetres) but wither.
Put the small beaker inside the greater beaker and full both of the beakers with water.
Put the ruler close to the bigger beaker make the light by 30 centimeter of the big beaker.
Create a piece of elodea (В±6 cm long) inside small beaker.
Begin the timer and depend how many...
