What are two ways to increase photosynthesis?
Photosynthesis can be increased by raising the carbon dioxide concentration surrounding Rubisco, either by CO2-concentrating mechanisms used by C4 plants, cyanobacteria, and algae, or by enriching the atmosphere, which is happening as a result of the human use of fossil fuels.
What are the 4 factors that affect photosynthesis?
Photosynthesis is affected by light, temperature, water, and CO2. Stomata affect the process of transpiration and do not affect photosynthesis.
Why does the rate of photosynthesis increase with light intensity?
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.
How does water affect the rate of photosynthesis?
Water affects the rate of photosynthesis indirectly. When the water supply is limited then stomatal closure affects the rate of photosynthesis. Water stress causes the stomata to close and thereby reduces carbon dioxide availability.

What are 3 factors that affect photosynthesis?
The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.
What is photosynthesis and what factors affect it?
Factors affecting photosynthesis are: Carbon dioxide – increase in the concentration of carbon dioxide can enhance the rate of photosynthesis. The intensity and quality of light affects the rate of photosynthesis. Photosynthesis is affected by temperature.
What are the factors needed for photosynthesis?
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.
Why is the rate of photosynthesis affected by temperature?
The rate of photosynthesis is also affected by temperature because the reactions of photosynthesis are controlled by specific enzymes. At low temperatures photosynthesis happens more slowly. A limiting factor is a factor that can limit the rate of photosynthesis if it is in short supply.
Why do paraffin lamps increase photosynthesis?
The use of paraffin lamps inside a greenhouse increases the rate of photosynthesis because the burning paraffin produces carbon dioxide as well as heat. previous. 1. 2. Page 2 of 2. next. up. down.
Why do we need a greenhouse?
A greenhouse can be used to overcome the limiting factors of photosynthesis. This allows plants to grow faster as they are making more food.
How does the rate of photosynthesis increase?
As with other chemical reactions, the rate of photosynthesis increases as the temperature rises. Photosynthesis is controlled by enzymes, which become denatured if the temperature is too high. As a result, the rate of photosynthesis reaches its maximum at an optimum temperature, then decreases. The maximum rate is determined by ...
What are the factors that affect the rate of photosynthesis?
There are several limiting factors which can reduce the rate of photosynthesis, eg temperature, light intensity and carbon dioxide concentration.
How does light intensity affect photosynthesis?
Light provides the energy needed for photosynthesis. Increasing the light intensity increases the rate of photosynthesis, provided plenty of carbon dioxide and water are available . The maximum rate is determined by the other factors involved.
Why is carbon dioxide needed for photosynthesis?
Carbon dioxide is needed for photosynthesis. Increasing the carbon dioxide concentration increases the rate of photosynthesis, provided the plant is warm enough, and has plenty of light and water. The maximum rate is determined by the other factors involved.
