How does oxygen production relate to the rate of photosynthesis quizlet?
how does oxygen production relate to the rate of photosynthesis? Greater flow of oxygen corresponds to a higher rate of photosynthesis. Why would it be hard to find the ideal light intensity if the temperature were very hot or cold.

How can oxygen production measure the rate of photosynthesis?
Measuring photosynthesis via the production of oxygen Oxygen can be measured by counting bubbles evolved from pondweed, or by using the Audus apparatus to measure the amount of gas evolved over a period of time.
How would an increase in oxygen affect the rate of photosynthesis?
The effect of oxygen on photosynthesis depends on plant species and on some internal and environmental conditions. Oxygen inhibits the photosynthesis of C3 plants at atmospheric CO2 concentration (Varburg effect). Inhibition of photosynthesis by oxygen is reduced by increase of the C02 concentration.
What does not affect the rate of photosynthesis?
Although the light dependent reactions of photosynthesis are not affected by changes in temperature, the light independent reactions of photosynthesis are dependent on temperature. They are reactions catalysed by enzymes. As the enzymes approach their optimum temperatures the overall rate increases.
What are the factors that affect the rate of photosynthesis and respiration?
Several factors can affect the rate of photosynthesis:light intensity.carbon dioxide concentration.temperature.
What are 3 factors that affect the rate at which photosynthesis occurs?
Three factors that affect the rate of photosynthesis are temperature, light intensity, and the availability of water.
What are the factors affecting photosynthesis process?
The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.
What temperature will result in the highest rate of photosynthesis?
At medium temperatures, between 50 and 68 degrees Fahrenheit, or 10 and 20 degrees Celsius, the photosynthetic enzymes work at their optimum levels, so photosynthesis rates gauge high. Depending on the particular plant in question, set the greenhouse thermostat to a temperature within this range for best results….
What is meant by the rate of photosynthesis?
The Rate of Photosynthesis Chlorophyll concentration – High chlorophyll concentration gives a high rate of photosynthesis. Carbon dioxide concentration – Increasing the carbon dioxide concentration increases the rate of photosynthesis because carbon dioxide is a reactant in photosynthesis.
What is the maximum rate of photosynthesis?
Photosynthetic capacity (Amax) is a measure of the maximum rate at which leaves are able to fix carbon during photosynthesis. It is typically measured as the amount of carbon dioxide that is fixed per metre squared per second, for example as μmol m−2 sec−1.
Who detected the maximum rate of photosynthesis?
What is the difference between photosynthesis rate and net photosynthesis rate?
Photosynthesis rate or gross photosynthesis rate is the total rate of fixation of carbon (reduction of CO2) without taking into consideration the amount of CO2 lost during respiration. Net photosynthesis rate is the rate of carbon fixation after subtracting the ate of CO2 lost during the respiration.
Why does more light increase the rate of photosynthesis?
As you rise from low light intensity to higher light intensity, the rate of photosynthesis will increase because there is more light available to drive the reactions of photosynthesis. At a very high intensity of light, the rate of photosynthesis would drop quickly as the light starts to damage the plant.
What light intensity will maximize the rate of photosynthesis?
The highest light intensity and CO2 level will maximize the rate of photosynthesis. Why would it be hard to find the ideal light intensity if the temperature were very hot or cold? If the temp were extremely hot or cold, then oxygen production would be near zero no matter what light intensity value you use.
What color of light will maximize the rate of photosynthesis?
How do greenhouses increase the rate of photosynthesis?
Increasing the carbon dioxide in the growing area will let the plant use the excess water and energy that is stored in the leaves . This explains that photosynthesis and growth rate can be increased by supply of additional light and carbon dioxide to the greenhouse.
How do you maximize the rate of photosynthesis?
When in short supply, light can be maximized by ensuring the greenhouse glazing is clean and by minimizing overhead obstructions such as hanging baskets. Sometimes that isn’t sufficient though, so growers provide high-intensity lighting to increase plant growth.
What is the process that can reduce the rate of photosynthesis?
There are several limiting factors which can reduce the rate of photosynthesis , eg temperature, light intensity and carbon dioxide concentration.

Why do plants grow better in a greenhouse?
Plants need moisture, warmth and light to grow. A greenhouse stabilises the growing environment by buffering the ambient temperature and protecting the plants from extreme cold. It supports your plants in a nurturing, caring environment and provides just the right conditions for plant growth….
