Temperature, light intensity and carbon dioxide levels vary at different times of the day and have an effect on each other, hence the photosynthesis rate.
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 . 1. Effect of Carbon dioxide: Being one of the raw materials, carbon dioxide concentration has great effect on the rate of photosynthesis.
What are three factors that affect the rate at which photosynthesis occurs?
- Light intensity. Without enough light, a plant cannot photosynthesise very quickly – even if there is plenty of water and carbon dioxide. ...
- Carbon dioxide concentration. ...
- Temperature.
What are the 3 process of photosynthesis?
The three events that occur during the process of photosynthesis are: (i) Absorption of light energy by chlorophyll. (ii) Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen . (iii) Reduction of carbon dioxide to carbohydrates.
What are the three abiotic factors that affect 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).
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.
Does photosynthesis continues to increase with temperature?
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 .
Which process 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 .
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.
What is the most important limiting factor in photosynthesis?
Carbon dioxide concentration is therefore an important limiting factor for photosynthesis.
Do plants take in oxygen?
Most folks have learned that plants take up carbon dioxide from the air (to be used in photosynthesis) and produce oxygen (as a by-product of that process), but less well known is that plants also need oxygen . ... So plants need to breathe — to exchange these gases between the outside and the inside of the organism.
What is the first stage of photosynthesis called?
Photosynthesis occurs in two stages. In the first stage, light-dependent reactions or light reactions capture the energy of light and use it to make the energy-storage molecules ATP and NADPH. During the second stage, the light-independent reactions use these products to capture and reduce carbon dioxide.
What is the first step of photosynthesis called?
The first step of photosynthesis is the absorption of light energy and the loss of electrons from chlorophyll . Photosynthesis is a process by the plant to produce food by absorbing light of a certain wavelength and used to convert water and carbon dioxide and minerals into oxygen-rich and energy-rich organic compounds.
What are 4 examples of abiotic factors?
Examples of abiotic factors are water, air, soil, sunlight, and minerals . Biotic factors are living or once-living organisms in the ecosystem.
What are the 7 abiotic factors?
In biology, abiotic factors can include water, light, radiation, temperature, humidity, atmosphere, acidity, and soil .
Is pH abiotic or biotic?
Abiotic factors are the physical and chemical conditions of an environment. For example : heat, salinity, pressure, light, wind, pH ... Biotic factors are all the biological conditions of an environment for a specie/taxa.
