Frequent question: What are two environmental factors that affect photosynthesis?

What are 2 factors that affect photosynthesis and explain why?

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 the four 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.

What is the environmental impact of photosynthesis?

It provides the source of energy that drives all their metabolic functions and the oxygen required for respiration. Photosynthesis can be critical to mitigating the climate changing effects of atmospheric greenhouse gasses and the restoration of soil organic matter promoting regeneration.

What are the two factors necessary for photosynthesis?

Carbon dioxide, sunlight, and water are essential factors for photosynthesis in plants.

IMPORTANT:  How is the climate along the coast?

What factors affect photosynthesis quizlet?

Among the most important factors that affect photosynthesis are temperature, light intensity, and the availability of water.

Does temperature affect photosynthesis?

Temperature. … As with any other enzyme-controlled reaction, the rate of photosynthesis is affected by temperature. At low temperatures, the rate of photosynthesis is limited by the number of molecular collisions between enzymes and substrates. At high temperatures, enzymes are denatured .

What are some environmental factors that affect the rate of photosynthesis and how?

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 affects photosynthesis the most?

The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.

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.

How does the greenhouse effect affect photosynthesis?

Plants consume carbon dioxide—a significant greenhouse gas—in the process of photosynthesis. The reduction of carbon dioxide in the atmosphere has an indirect cooling effect. Plants also cool the atmosphere because they release water vapor when they get hot, a process similar to sweating.

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.

IMPORTANT:  What are the 3 major types of physical and biological evidence for climate change?

How can the environment affect plants?

In some cases, poor environmental conditions (e.g., too little water) damage a plant directly. In other cases, environmental stress weakens a plant and makes it more susceptible to disease or insect attack. Environmental factors that affect plant growth include light, temperature, water, humidity, and nutrition.

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

  • Temperature.
  • Intensity and wavelength of sunlight.
  • Carbon dioxide concentration.
  • Water.

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 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.
