Temperature, light intensity, carbon dioxide levels, water, oxygen and chlorophyll. The rate of photosynthesis increases as the temperature increases. However, the rate declines after the temperature reaches an optimal level (usually around 35 C).
What will slow down rate of photosynthesis?
Three factors can limit the rate of photosynthesis: light intensity, carbon dioxide concentration and temperature.
What are the 4 factors that affect the rate of photosynthesis?
What factor most affects the rate of photosynthesis? The main variables which affect photosynthesis are light, water, CO2 concentration and temperature.
What makes a reaction go faster in photosynthesis?
Without enough light, a plant cannot photosynthesise very quickly – even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis , until some other factor – a limiting factor – becomes in short supply.
What are three factors that affect the rate at which photosynthesis occurs quizlet?
Among the most important factors that affect photosynthesis are temperature, light intensity, and the availability of water.
Which factor least influences the rate of photosynthesis?
The major limiting factors in this process are light intensity, temperature, and carbon dioxide levels. For both light intensity and temperature, if the level is too low or too high, the rate of photosynthesis declines rapidly.
What factors affect how quickly or slowly photosynthesis occurs?
The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.
What five factors affect photosynthesis and its rate?
The environmental factors which can affect the rate of photosynthesis are carbon dioxide, light, temperature, water, oxygen, minerals, pollutants and inhibitors.
Which factor can affect the rate of photosynthesis by denaturing enzymes in the plant?
As temperature increases the number of collisions increases, therefore the rate of photosynthesis increases. However, at high temperatures, enzymes are denatured and this will decrease the rate of photosynthesis.
Which is the major limiting factor for photosynthesis?
Light. As light intensity increases so too does the rate of photosynthesis until a certain point where the graph levels off. At lower light intensities, light is the limiting factor because an increase in light causes an increase in photosynthesis.
Why does the rate of photosynthesis decrease at higher temperatures?
Photosynthesis is an enzyme mediated process. We know that enzymes work in optimum range of temperature. When the temperature goes beyond this range, an enzyme cannot work. Due to this, the rate of photosynthesis decreases at higher temperature.
What are the factors affecting photosynthesis Class 10?
There are several factors that affect the rate of photosynthesis. Light intensity, water, soil pH, carbon dioxide concentration, temperature and other climatic conditions are the main factors affecting the rate of photosynthesis.
What is the rate of photosynthesis?
The rate of photosynthesis is a gross measure of the rate at which a plant captures radiant energy and fixes it in organic carbon compounds.
How light intensity affects the rate of photosynthesis?
As light intensity increases the rate of photosynthesis also increases. This is because photosynthesis is an energy requiring reaction, endothermic. More light energy will increase the rate at which oxygen is given off so more bubbles of oxygen will be produced per minute.
Why does increasing temperature increase the rate of photosynthesis?
Temperature – Increasing the temperature increases the rate of photosynthesis because more energy is provided. However, if the temperature is increased to above about 45°C, the enzymes that catalyse (speed-up) the reaction begin to denature (not work anymore).
How do abiotic factors affect the rate of photosynthesis?
The rate of photosynthesis in a plant can be determined by three external factors: temperature, light intensity, and available carbon dioxide concentration. In any given situation any one of these may become a limiting factor if they are below the optimal level (Alott and Mindorff).
