Question: What environmental variables affect the rate of photosynthesis?

Three factors can limit the rate of photosynthesis: light intensity, carbon dioxide concentration and temperature.

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 the 4 factors that affect the rate of photosynthesis?

What factor most affects the rate of photosynthesis? The main variables which affect photosynthesis are light, water, CO2 concentration and temperature.

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.

IMPORTANT:  How can we manage environmental health issues?

What affects photosynthesis the most?

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

What are the factors that affect the rate of photosynthesis which is considered the most important?

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.

Why does temperature affect the rate of photosynthesis?

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 four environmental factors that affect transpiration?

The rate of transpiration is affected by several factors, including:

  • temperature.
  • humidity.
  • wind speed.
  • light intensity.

What features or variables of the plant leaves might affect the net rate of photosynthesis?

the amount of light, the amount of carbon dioxide, and the temperature the plant is exposed to. these factors will affect the process of photosynthesis because photons of light energy are needed to excite the electrons in the thylakoid membrane.

What environmental factors might impact the rate at which the Calvin cycle occurs?

Factors Affecting the Calvin Cycle

The amount of carbon dioxide that the plant can access affects the Calvin cycle. A higher concentration of carbon dioxide means that the rate of the photosynthesis process can increase. In addition, the temperature affects the cycle.

What are the factors that affect the rate of photosynthesis and respiration?

Several factors can affect the rate of photosynthesis:

  • light intensity.
  • carbon dioxide concentration.
  • temperature.
IMPORTANT:  Best answer: How can you help maintain ecological balance?

How do greenhouse gases 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.

What factors speed up or slow down the rate of photosynthesis?

The environmental factors that speed up or slow down the rate of photosynthesis are temperature and the availability of sunlight and carbon dioxide. …

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.
