Carbon Dioxide and the rate of photosynthesis worksheet
Three factors can limit the speed of photosynthesis: light intensity, carbon dioxide concentration and temperature.
Carbon Dioxide and the rate of photosynthesis worksheet
If a plant does not receive adequate light it will attempt to
reach the light by growing taller.
This is why in rainforests, trees are in a constant battle to grew taller to absorb the sunlight better.
How Carbon Dioxide Concentration affects photosynthesis
The reason why carbon dioxide affects photosynthesis is because it is needed for the reaction of photosynthesis to occur:
Interestingly, if Carbon Dioxide is the limiting factor at a current point, speaking to the plant (for several hours, admittedly) will boost the rate of reaction, because carbon dioxide is produced by human speech.
In general, carbon dioxide is found in low concentration in the atmosphere, and so atmospheric carbon dioxide levels may be a major limiting factor on photosynthesis when at low levels.
They found that elevated CO2 increased rates of net photosynthesis in about 85% of the reported studies, while reducing stomatal conductances and rates of transpiration in approximately 75% of the cases analyzed....
Limiting factors of Photosynthesis.
The amount of CO2 is linear to that of the rate of photosynthesis, while blue light is the best light to grow plants in (next to sunlight, of course).
Just like a cake needs certain ingredients in order to turn out into a cake, in order for a plant to photosynthesize, it must have these "certain ingredients" in which this case is carbon dioxide and water, adequate light, and the proper temperature.
6CO2 + 6H2O ----------> (light energy) C6H12O6 + 6O2.
We can see from the equation of photosynthesis that certain factors are required for the process to occur.
The chlorophyll is present in the plants' chloroplasts.
The factors of photosynthesis all occur simultaneously.
How does the color of the light source affect the rate of photosynthesis?
Along with CO2 and water, in order for plants to photosynthesize, light is required.
As seen in the chart, these pigments favor the violet-blue light, so it can be deduced that plants under this light source will have a faster photosynthetic rate and green will prevent the process.
Spinacia oleracea (spinach)
fluorescent light bulbs (60-100watt) in blue, red, green, and regular colors.
paper towels (for clean up)
beakers for the solutions (500 mL is sufficient)
If it gets too cold, the rate of photosynthesis will decrease.
what factors affect the rate of photosynthesis?
If it gets too cold, the rate of photosynthesis will decrease. Plants cannot photosynthesise if it gets too hot.
how does light intensity affect the rate of photosynthesis?
Worksheet with data to draw and analyse graph related to effects of limiting factors on photosynthesis in agriculture.
how does temperature affect the rate of photosynthesis?
I am trying to find out if the distance of the pond-weed from a lamp will change the rate of photosynthesis.
Low light intensity lowers the rate of photosynthesis
Carbon dioxide and water are required to start photosynthesis and as long as maximum fixation is not reached and there are no limiting factors, the more CO2, the faster the reaction.
Photosynthesis Limiting Factors by bobfrazzle - …
Light is a very important factor in the rate of photosynthesis, in my project I am going to test that plants do need light in order to photosynthesise.
BBC - GCSE Bitesize: Factors limiting photosynthesis
Part I & II.
Rate of photosynthesis
Conclusion to Hypothesis I
The hypothesis was correct and accepted.
Experiments to show factors required by Photosynthesis
Furthermore, I predict that if the light intensity increases, the rate of photosynthesis will increase at a proportional rate and more oxygen will be produced and therefore the oxygen levels will increase.
Free rate of photosynthesis Essays and Papers
Farmers use methods such as burning methane/oil-fired heaters in greenhouses to increase levels of CO2 because enhanced levels of CO2 will increase the rate of photosynthesis, provided that no other factor is limiting the process.

It will be very interesting to see how light will influence the rate of photosynthesis in plants and what will happen if they do not get the required light in order to produce starch .
Factors of photosynthesis ANS 3 - YouTube
This process is also affected by the temperature surrounding the plant (the species of plant we experimented with, pond weed, photosynthesised best at around 20 degrees centigrade.) Light, temperature & CO2 are known as limiting factors, and each is as important as the next in photosynthes...
