what are the three factors that affect photosynthesis

This topic is especially important to scientist and farmers. For example, less light, insects that chew on leaves, less water can make plants such as tomato plant suffer and produce less yield. The green cells produce starch in variegated leaves. If I had turned the security lights on my house on, the plants in my garden might possibly have photosynthesised faster. Let's talk about those in more detail.

Factors Affecting The Rate Of Photosynthesis

what are the three factors that affect photosynthesis

The limiting factors which affect photosynthesis are: 1. This means that a cell lacking nutrients has a lower respiration rate than a cell that has access to all the nutrients it requires, states the Journal of Experimental Botany. And then as it gets colder, the enzymes move around more slowly and hence the rate of reaction drops. The curve is very shallow and levels off towards a light intensity of 350 - 400. There is an initial increase in the rate of photosynthesis at this temperature. Now if the carbon dioxide concentration is gradually increased, the rate of photosynthesis will also increase correspondingly until the assimilation rate of 5 mg carbon dioxide per hour has been reached.

Extracts of this project must not be included in any projects that you submit for marking. This experiment could be improved in a number of ways. It reduces the rate of photosynthesis. Arnon 1954 has demonstrated that cell free chloroplasts are capable of carrying out photosynthesis. But this is soon followed by a decline. Scientifically, this does not adequately address the true range of spectral color. There is a point in light intensity where there is no gaseous exchange in photosynthesis.

This is true of a lot of chemical reactions, especially biological ones. It becomes maximum at bright daylight. Chloroplasts mostly found in the mesophyll layer contain a green substance called chlorophyll. Therefore, neurons have a higher cellular respiration rate than lipid cells. Too cold and their productivity slows down to zero.

The remaining distances are 0. The increase in the amount of carbon dioxide increases the photosynthesis. The higher the temperature is, the higher the cellular respiration rate is. Those animals can, in turn, be eaten by other animals carnivores and omnivores , passing energy along the food chain. If the temperatures are above or below this range, the enzymes may be affected, slowing down the rate of photosynthesis.

Here a rise in light intensity has no affect on the rate of photosynthesis as the other factors such as temperature and carbon dioxide become limiting. By understanding the factors that affect the rate of photosynthesis they can do work to try and increase the rate of photosynthesis to increase the yield of a crop. Near the end of the line it looks as if the rate of reaction is hit by another limiting factor. Distilled Water With the distilled water the rate of reaction went up from 0. Experiments of Engelmann proved that maximum photosynthesis occurs in the red and blue part of the spectrum.

The rate rises to 1. Not picking up animal waste products.

Thus the chloroplasts are the complete photosynthetic units. Chlorophyll is needed for photosynthesis. It starts after some time.

Optimum or saturation intensities may vary with different plant species e. There are two types of photoreceptors: cones which are sensitive to color and rods which are more sensitive to intensity. To explain the meaning of his principle Blackman cited the following example. But the water content of the leaf often acts as a limiting factor indirectly. There are two reasons of this. Rate of the process varies with the light intensity, temperature, and concentration of carbon dioxide in the plant's atmosphere.
