- Three factors can limit the speed of photosynthesis - light intensity, carbon dioxide concentration and temperature. Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide. Increasing the light intensity will boost the speed of photosynthesis.

- At high light in-. tensities, however, an increase in temperature or CO. 2. concentration greatly accelerated photosynthesis. Black-. man concluded that photosynthesis consists of an initial. set of what he called “light” reactions, that are largely in-. dependent of temperature, and a second set of “dark” re-.

- Gradually the rate falls of and at a certain light intensity the rate of photosynthesis stay constant (from point B to C on the graph). 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.

General Chemistry/Print version with light, less sun= less photosynthesis, more sun= more photosynthesis. This …is because there is a 'light dependant reaction' as part of photosynthesis, and therefore photosynthesis can only happen when there is enough light. CO2 is needed for photosynthesis. The more co2, the faster the rate of photosynthesis. Increasing the Temperature increases the rate. This is because there are enzymes in the process of photosynthesis, and with enzymes, the rate increases with temperature (up to a point, when it is too hot for the enzymes to work).

- This is because an increase in light intensity results in an increase of rate of photosynthesis. Photosynthesis requires gaseous exchange and the stomata is the pore in which gaseous exchange takes place. Therefore an increase in photosynthesis results in an increase in stomata opening (increased gaseous exchange) .

Experiment to investigate the effect of Carbon Dioxide on the Rate of Photosynthesis Light 6H2O + 6CO2 C6H12O6 + 6O2 Water + carbon chlorophyll glucose + oxygen dioxide It can be seen from the equation that water and carbon dioxide are very important in photosynthesis as without the process cannot take place.arbon dioxide provides carbon atoms in the reaction to form glucose. It can be seen that there are many factors which photosynthesis depends on and they will affect the plant. The following factors are the four main factors, which affect the rate of photosynthesis (how quickly photosynthesis takes place).

Experiment to investigate the effect of Carbon Dioxide on the Rate of Photosynthesis Introduction. Experiment to investigate the effect of Carbon Dioxide on the Rate of Photosynthesis Aim: To find out whether the increase in carbon dioxide affects the rate at which oxygen is released (this will effectively measure the rate of photosynthesis) from a Canadian pondweed, elodea.arbon dioxide provides carbon atoms in the reaction to form glucose. It can be seen that there are many factors which photosynthesis depends on and they will affect the plant. The following factors are the four main factors, which affect the rate of photosynthesis (how quickly photosynthesis takes place).

Factors that Affect the Chemical Reaction Rate Factors that influence the rate of a chemical reaction include temperature, state of matter of reactants, concentration, presence of catalysts, and pressure. PM Images, Getty Images. Anne Marie Helmenstine, Ph.D.or solids, the shape and size of the reactants makes a big difference in the reaction rate. Presence of Catalysts and Competitors. Catalysts (e.g., enzymes) lower the activation energy of a chemical reaction and increase the rate of a chemical reaction without being consumed in the process.

- Any change in the level of a limiting factor will affect the rate of. reaction. For example, the amount of light will affect the rate of photosynthesis. If there is no light, there will. be no photosynthesis. As light intensity increases, the rate of photosynthesis will increase as long. as other factors are in adequate supply. As the rate increases, eventually another factor will come. into short supply.

#44 Limiting factors in photosynthesis 1 In photosynthesis CO2 is a key limiting factor. 2  The usual atmospheric level of CO2 is 0.03%. 3  In perfect conditions of water availability, light and temperature this low CO2 level holds back the photosynthetic potential.

What factors affect the rate of diffusion? Some of the factors that affect the rate at which particles diffuse include: the particle's molecular weight, temperature, concentration difference, diffusion distance, permeability and surface area. Pressure is also known to affect the rate of diffusion since it increases the speed of molecules.

- At a particular light intensity, the so-called light saturation point, the rate of O2 evolution levels off. Any further increase in the amount of light striking the leaf does not cause an increase in the rate of photosynthesis--the amount of light is said to be 'saturating' for the photosynthetic process.

#44 Limiting factors in photosynthesis Limiting factor is something present in the environment in such short supply that it restricts life processes. Three factors can limit the speed of photosynthesis-light intensity, carbon dioxide concentration and temperature.

What is the effect of temperature on photosynthesis? The higher the temperature then typically the greater the rate of photosynthesis, photosynthesis is a chemical reaction and the rate of most chemical reactions increases with temperature. However, for photosynthesis at temperatures above 40°C the rate slows down.

- Plants regulate the rate of transpiration by opening and closing of stomata (Figure Figure 1). There are, however, a number of external factors that affect the rate of transpiration, namely: temperature, light intensity, humidity, and wind.

How does a greenhouse speed up the rate of photosynthesis? A greenhouse dosn't speed up the rate of photosynthesis. what a greenhouse does, is it uses solar energy to keep the air inside the greenhouse at a higher temperature, so in colder locations, the plants inside will be in a more tropical environment, so they will be more efficient.

Overall Process of Photosynthesis Overall Process of Photosynthesis. The best‐understood reaction for the synthesis of glucose, and probably the most important quantitatively, is photosynthesis. Photosynthesis converts carbon from carbon dioxide to glucose with reducing equivalents supplied from water and energy supplied from light. The energy in light is dependent on its wavelength, and is given by the following relationship. The Greek letter nu, ν, stands for the frequency of the light, h is a constant called Planck’s constant, c is the speed of light, and λ is the wavelength. In other words, the energy of light is inversely proportional to its wavelength. The longer the wavelength, the less energy it contains.

- She disappeared with the kitten, returning soon back up to the ship. A little later, here she came again with another kitten, down the gangplank. This was repeated until all the kittens were off the ship and the cat and kittens disappeared. Jim, got the message, collected his things and also left the ship.

Factors Affecting Photosynthesis Factors Affecting Photosynthesis. Low light intensity lowers the rate of photosynthesis. As the intensity is increased the rate also increases. However, after reaching an intensity of 10,000 lux (lux is the unit for measuring light intensity) there is no effect on the rate.

Factors Affecting Photosynthesis Water is an essential factor in photosynthesis. The effect of water can be understood by studying the yield of crops which is the direct result of photosynthetic activity. It is found that even slight deficiency of water results in significant reduction in the crop yield.

- For example, the amount of light will affect the rate of photosynthesis. If there is no light, there will be no photosynthesis. As light intensity increases, the rate of photosynthesis will increase as long as other factors are in adequate supply.As the rate increases, eventually another factor will come into short supply. The graph below shows the effect of low carbon dioxide concentration. Temperature and rate of photosynthesis Although the light dependent reactions of photosynthesis are not affected by changes in temperature, the light in dependent reactions of photosynthesis are dependent on temperature. They are reactions catalysed by enzymes.
