What are the five environmental factors that affect 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 3 environmental factors that can affect photosynthesis and explain their effects?
We learned that light intensity, carbon dioxide concentration, and temperature are the three main factors that impact photosynthesis. Greater light intensity leads to higher photosynthesis rates, as does increased carbon dioxide concentration.
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 three environmental 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.
What are the three environmental factors?
Environmental factors include temperature, food, pollutants, population density, sound, light, and parasites.
What environmental factors can affect photosynthetic rate and how?
Three factors can limit the rate 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. …
- Carbon dioxide concentration. …
What are the factors affecting 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 the factors affecting photosynthesis Class 10?
The factors affecting rate of photosynthesis are: Temperature Intensity and wavelength of sunlight Carbon dioxide concentration Water
- Intensity and wavelength of sunlight.
- Carbon dioxide concentration.
Which environmental factors does not affect the rate of photosynthesis?
Light and rate of photosynthesis
Light dependent reactions use light energy and so are not affected by changes in temperature. As light intensity is increased further, however, the rate of photosynthesis is eventually limited by some other factor. So the rate plateaus.
What are the factors affecting photosynthesis Class 11?
The plant factors include the number, size, age and orientation of leaves, mesophyll cells and chloroplasts, internal CO2 concentration and the amount of chlorophyll. The external factors would include the availability of sunlight, temperature, CO2 concentration and water.
What is the major limiting factor for photosynthesis?
As carbon dioxide concentrations increase, so too does the rate of photosynthesis until a certain point where the graph levels off. At lower carbon dioxide concentrations carbon dioxide is the limiting factor because an increase in carbon dioxide causes an increase in photosynthesis.
What factors affect photosynthesis lab?
1) the variables of light intensity, temperature, carbon dioxide, light quality all influence the rate of photosynthesis.
What are the 5 requirements for photosynthesis?
In order to carry out photosynthesis, green plants need several ingredients.
- Chlorophyll. Chlorophyll, the pigment in plants that makes them green, is essential to the photosynthetic process. …
- Sunlight. The process cannot work without an energy input, and this comes from the sun. …
- Water. …
- Carbon Dioxide.
How does global warming affect photosynthesis?
Climate change affects plants in many different ways. Increasing CO(2) concentration can increase photosynthetic rates. … With increasing temperature, vapour pressure deficits of the air may increase, with a concomitant increase in the transpiration rate from plant canopies.
What factors affect photosynthesis and cellular respiration?
the intensity of the light being absorbed by the chloroplasts. the concentration and availability of CO2 (Carbon Dioxide) the temperature.
