Effects of different colors of light on the photosynthesis rate.

In this experiment we were told that we would be measuring the rate of photosynthesis.

Photosynthesis is the procedure all plants go through to make food.

A limiting factor is a factor that controls a process. Light intensity, temperature and carbon dioxide concentration are all factors which can control the rate of photosynthesis. Usually, only one of these factors will be the limiting factor in a plant at a certain time. This is the factor which is the furthest from its optimum level at a particular point in time. If we change the limiting factor the rate of photosynthesis will change but changes to the other factors will have no effect on the rate. If the levels of the limiting factor increase so that this factor is no longer the furthest from its optimum level, the limiting factor will change to the factor which is at that point in time, the furthest from its optimum level. For example, at night the limiting factor is likely to be the light intensity as this will be the furthest from its optimum level. During the day, the limiting factor is likely to switch to the temperature or the carbon dioxide concentration as the light intensity increases.

Photosynthesis need light to work, so light therefore should speed up the rate of photosynthesis.

Photosynthesis consists of two connected sets of reactions....

The result of two light reactions is a total of six oxygen molecules (6 O2) released into the air as byproducts and 12 NADPH2 (24 H) carried over to the dark reaction of photosynthesis....

How does light intensity and duration affect the rate of photosynthesis?


Rate of Photosynthesis in Pond-Weed :: Papers

There are four things that are required by the plant before it can carry out photosynthesis, they are light, chlorophyll, carbon dioxide and water ....

Effect of Light Wavelength on Rate of Photosynthesis

Farmers can use their knowledge of these limiting factors to increase crop growth in greenhouses. They may use artificial light so that photosynthesis can continue beyond daylight hours, or in a higher-than-normal light intensity. The use of paraffin lamps inside a greenhouse increases the rate of photosynthesis because the burning paraffin produces carbon dioxide, and heat too.

How temperature affects the rate of photosynthesis.

I think this because the plant may use up all of the carbon dioxide (Sodium hydro carbonate) and the plant can have as much light as it needs but if it does not have any carbon dioxide it will not be able to photosynthesise....

Home Effects Of Wavelength And Light Intensity On Photosynthetic ..

Four things are needed to make this process work and this gives two thing: the four things needed are light from the sun, carbon dioxide diffuses from the air, water from the soil and chlorophyll in the leaves....

Why the rate of Photosynthesis is higher in red light …

My graph shows that when the Elodea was 10cm away from the lamp
the rate of photosynthesis was high with there being around one bubble
produced per second The average amount of bubbles produced in 30
seconds was 58.

Investigating factors affecting the rate of photosynthesis

When the Elodea was 20cm away from the lamp the rate
of photosynthesis decreases by more half as much with the average
number of bubbles produced being only 24.
