Three factors can limit the rate of photosynthesis: light intensity, carbon dioxide concentration and temperature .
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.
What are the 6 factors that affect photosynthesis?
- the rate of oxygen output.
- the rate of carbon dioxide uptake.
- the rate of carbohydrate (glucose) production.
Which of the following environmental factors would affect the rate of photosynthesis least?
“Three factors can limit the speed of photosynthesis: light intensity, carbon dioxide concentration and temperature . Light intensity Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide.
What are the environmental factors which affect rate of photosynthesis?
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 environmental factors?
Environmental factors include temperature, food, pollutants, population density, sound, light, and parasites . The diversity of environmental stresses that have been shown to cause an increase in asymmetry is probably not exclusive; many other kinds of stress might provide similar effects.
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 are the major factors affecting photosynthesis?
- 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 factors that affect photosynthesis Class 7?
Light intensity, water, soil pH, carbon dioxide concentration, temperature and other climatic conditions are the main factors affecting the rate of photosynthesis.
What are 3 factors needed for photosynthesis?
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight . for photosynthesis. Carbon dioxide enters through tiny holes in a plant's leaves, flowers, branches, stems, and roots. Plants also require water to make their food.
Which plants respond to higher temperature and show higher rate of photosynthesis?
It has long been recognized that C4 plant species have a higher temperature optimum for photosynthesis than C3 plants due to the operation of a CO 2 -concentrating system that inhibits Rubisco oxygenase activity (Berry and Björkman, 1980; Edwards and Walker, 1983).
Which of the following will not affect photosynthesis?
Photosynthesis uses maximum up to 1.5 % light in the process and so light is generally not a limiting factor at high intensity. However, the light becomes a limiting factor in low intensity because no matter how much water or CO2 is present, without light photosynthesis cannot occur.
What factors affect transpiration?
- temperature.
- humidity.
- wind speed.
- light intensity.
How do humans impact photosynthesis?
Ways of Human impact
Humans can also affect the water needed for photosynthesis by pollution through chemicals, factory emmissions, dumping , etc.
How carbon dioxide affects the rate of photosynthesis?
Carbon dioxide concentration
Carbon dioxide – with water – is one of the reactants in photosynthesis. If the concentration of carbon dioxide is increased , the rate of photosynthesis will therefore increase.
What are the six environmental factors?
When considering strategic business decisions, businesses analyze the six general environmental forces: political, economic, sociocultural, technology, environment and legal factors .
