Effects of different colors of light on the photosynthesis rate.

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

Photosynthesis takes place in all plants that contain chlorophyll.



Repeat this Experiment:


In another experiment, Ingenhousz, placed a small green aquatic plant in a transparent container of water and exposed the container to bright sunlight.

[Again, no change will occur because no plant is present and photosynthesis is not occurring therefore the acidity of the solution remains the same.]

So by level of light you probably mean lightintensity which is something that can be measured.Light intensity is usually defined as theenergy hitting an area over some time period.So in the case of a plant, a higher lightintensity means more packets of light called“photons” are hitting the leaves. As you rise fromlow light intensity to higher light intensity, therate of photosynthesis will increase because thereis more light available to drive the reactions ofphotosynthesis. However, once the light intensitygets high enough, the rate won’t increase anymorebecause there will other factors that are limitingthe rate of photosynthesis. A limiting factorcould be the amount of chlorophyll molecules thatare absorbing the light. At a very high intensityof light, the rate of photosynthesis would dropquickly as the light starts to damage the plant.


For a simple experiment about photosynthesis, ..

When photosynthesis takes place, plants use the suns energy to combine carbon dioxide from the air with water from the soil to create glucose (a carbohydrate)....

What Is Photosynthesis? From Light Energy to Chemical …

With too little light, photosynthesis cannotoccur either and the plant suffers without theproduction of sugars. There are many complicatinginteractions between plants and light. I hope thatyou continue to investigate this as the story getsmore interesting and exciting the deeper you go.

Photosynthesis Science Fair Projects and Experiments

The chemical equation of photosynthesis is: [IMAGE]6CO2 + 6H20 C6 H12 O6 + 6O2 it has been proven many times that plants need light to be able to photosynthesize , so you can say that without light the plant would neither photosynthesize or survive....

The Effects of Elevated Carbon Dioxide Levels on the Transpiratoin Rates of Zonal Geranium PlantsHow Does the Introduction of NaF Affect the Rate of Photosynthesis in Isolated Chloroplasts?

One of the important factor required for photosynthesis is sunlight

Variables: The variables that might affect the rate of photosynthesis in this experiment are: Temperature: When the temperature rises so does the rate of photosynthesis; this is because as the temperature around the plant rises the enzymes controlling photosynthesis inside the chloroplasts heat up and start moving around faster, the fast moving molecules collide with other fast moving enzymes causing them to react....

Immediatelyafter exposure to 14CO2, the plant's photosynthetic tissue iskilled by immersing it in boiling alcohol, and all of the biochemical reactions cease.
