Photosynthesis Investigation I would like to have a look at what may speed up the rate of photosynthesis in plants. The items that I think will speed up photosynthesis are as follows:

Photosynthesis Investigation Hypothesis A plant needs to use photosynthesis to survive just like we need to use reparation to survive. Us mammals inhaling oxygen and exhaling mainly carbon dioxide but for plants it's the opposite way around, they inhale carbon dioxide in there leafs and exhales oxygen. The idea of producing oxygen from the use of sunlight and carbon dioxide may sound strange but it is true. To produce oxygen a plant goes through an ever-lasting cycle, which is shown below: Carbon Dioxide + Water Oxygen + Sugar / Glucose (Gas) (Liquid) (Gas) (Solid) This cycle is ever lasting until the plant dies, this process may go fast or may go slow it all depends on the size and the age of the plant and also the amount of sunlight in the area. A plant needs the following for good health and to receive the requirements it needs to accomplish PHOTOSYNTHESIS. These are: * Carbon Dioxide * Light * Minerals * Water * Chlorophyll * Heat (some plants) ...read more.


I think light is the most important because with out light plants cannot grow, never mined accomplishing the cycle of photosynthesis. Given a plant an overdose doesn't sound good but I think it will do some good. Given the plant a larger amount of sunlight than it usually receives may shock it but will I think force the plant to inhale more carbon dioxide and exhale a lot more oxygen. This will also I think speed the cycle of photosynthesis quickly and will finally even out at a high output point. Fair test To keep this test fair I will be doing the following: * Keep the heat of the water the same * Use the same pond weed each time * Use the same amount of water each time * Use the same sized beaker * Use the same light * Do this in an area, which will not increase in light, heat or carbon dioxide amount. Plan The equipment I will be using for this experiment is as follows: * 500ml beaker * A lot of warm carbonated water * A lamp * A ...read more.


After a steady drop around 80 or 90cm's away the line levelled off. It started to level off because the plant was no longer receiving surfactant light from the 60-watt bulb, but from the surrounding light sours. Most of the graph shows this line of best fit with some anomalous results. Directly proportion Distance from lamp In all these experiments the plant was never performing to its full potential. This was because we only used a 60-watt bulb; there is even 200-watt bulb. With a 200-watt bulb I would expect the bubble output to be greater. Evaluation At the end I was pleased to find out nearly everything in my experiments worked out apart for the one or two anomalous results which never fitted in to my line of best fit but I over come that by redoing the experiment. I think I could have done these experiments more reliable if I had more time to do the experiments in and I had better measuring tools. If I redone this experiment I will defiantly do more tests and used more reliable tools. ...read more.

    This helps slow down the diffusion of water out of the leaf. 3. Bigger stomata and lots of stomata mean more water loss. In hot climates plants have fewer, smaller stomata on the underside of the leaf and no stomata on the upper epidermis.

  2. How temperature affects the rate of photosynthesis.

    Therefore from the dark stage the maximum amount of carbon dioxide is being fixed by Rubisco and the maximum amount of the unstable intermediate and eventually glucose is being formed. In the light stage the maximum amount of oxygen is being released by the enzyme controlling the photolysis of water

    Rate of photosynthesis

    The chlorophyll uses light energy to perform photosynthesis. It can only do it as fast as the light energy is arriving. 1) As the light level is raised, the rate of photosynthesis increases steadily but only up to a certain level.

  1. What is Photosynthesis?

    for the plant. It is only when the rate of photosynthesis is greater than the rate of respiration that CO2 will be taken in and excess O2 given out. ie. In darkness O2 is taken in and CO2 is given out - there is no p/s; in dim light the

  2. Rate of Photosynthesis

    Light intensity can be calculated using inverse square law, which states that if you double the distance you quarter the light intensity. The equation for light intensity is 1/d2 where d=distance. We now know that photosynthesis has three main limiting factors and one final factor related to the plant and not the surroundings.
