Investigating Factors Affecting the rate of photosynthesis.

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....

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

Introduction: "Photosynthesis is the conversion of light energy to chemical energy that is stored in glucose or other organic compounds; it occurs in plants, algae, and certain prokaryotes" (Campbell, G-16).

Factors Affecting Rate of Photosynthesis.

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

But a high increase in temperature slows down the rate of photosynthesis.

As the .Factors Affecting The Rate Of Photosynthesis Biology Essay.

Aim: We will be trying to see if light intensity has an effect on the rate of photosynthsis.

the rate begins to slow as the Farmers can use their knowledge of these limiting factors to increase crop . The line graph shows five years of data about a dog.

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.

If the amount of CO2 increases up to 0.1%, the rate of photosynthesis also increases.

Investigation into the Factors Affecting The Rate Of Photosynthesis.

Up until maximum fixation is reached and the reaction plateaus, an increase in CO2 would mean an increase in the rate of photosynthesis until a factor limits it or maximum fixation is reached.

WHS Bio 5 Factors that effect the Rate of Photosynthesis.

If solution-filled syringes with certain amounts of CO2 are tested to see how the increase of CO2 will affect the photosynthetic rate of spinach disks, then the more CO2, the faster the rate.


The rate of photosynthesis can vary depending.

If identical solution-filled syringes are tested to see how the color of the light source will affect the photosynthetic rate of spinach disks, then the syringe tested under the blue light would have the highest photosynthetic rate followed by red, regular colored, and finally green light.
All organisms are powered by energy.

what factors affect 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....

how does light intensity affect the rate of photosynthesis?

The energy, whether it'd come from burning coal, wood, plastic or even food all directly or indirectly come from sunlight in the process of photosynthesis (Raven & Johnson, 2002).

how does temperature affect the rate of photosynthesis?

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...
