What would most directly affect the photosynthetic activity of the plant cells?
Factors that influence the rate of photosynthesis The amount of light, the carbon dioxide supply, temperature, water supply, and the availability of minerals are the most important environmental factors that affect the rate of photosynthesis in land plants.
Which of the following changes would be most likely to affect the rate of photosynthesis?
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 factors can affect photosynthesis?
Several factors can affect the rate of photosynthesis:
- light intensity.
- carbon dioxide concentration.
- temperature.
Which of the following environmental changes would most likely increase the rate of photosynthesis in plants?
Light intensity 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.
How does wavelength affect photosynthesis?
Special pigments in chloroplasts of plant cells absorb the energy of certain wavelengths of light, causing a molecular chain reaction known as the light-dependent reactions of photosynthesis. The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm).
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 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 three factors affect the rate of photosynthesis?
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.
- Temperature.
What are 5 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 factors had the largest effect on photosynthetic rate?
The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.
What affects the rate of photosynthesis and why?
Three factors can limit the rate of photosynthesis: light intensity, carbon dioxide concentration and temperature.
How does wavelength affect plant growth?
The color or wavelength of light does affect photosynthesis, which is how plants can basically create their own food. Essentially, the reason why plants are green is they are absorbing the other wavelengths of light but reflecting back the green.
What are the factors that affect the rate of photosynthesis?
Several factors can affect the rate of photosynthesis: light intensity. carbon dioxide concentration. temperature. The amount of chlorophyll also affects the rate of photosynthesis: plants in lighting conditions unfavourable for photosynthesis may synthesise more chlorophyll, to absorb the light required.
How does carbon dioxide uptake affect photosynthesis?
So the carbon dioxide uptake increases. After a specific point, further increases in light intensity give ever smaller increases in photosynthesis. This results in the rate of carbon dioxide uptake slowing (point E on the graph). A similar graph will be obtained if oxygen production is plotted against light intensity.
Where does photosynthesis take place in plants and algae?
In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle—the chloroplast. Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP, are used by the photosynthetic cells to produce many organic molecules.
Which is better able to absorb light for photosynthesis?
Leaves with more chlorophyll are better able to absorb the light required for photosynthesis. These graphs have been plotted with rate of photosynthesis against the factor under investigation. If oxygen production or carbon dioxide uptake is used as a measure of photosynthetic rate, the graphs are slightly different.
