Question: How abiotic factors affect the rate of photosynthesis?

Abiotic factors include: Light intensity: limited light will limit photosynthesis. This will affect the distribution of plants, and therefore the distribution of animals that eat plants. … Temperature: temperature is a limiting factor for photosynthesis – and low temperature therefore limits growth of plants.

What abiotic factors could affect the rate of photosynthesis in a plant?

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 4 main abiotic factors that affect photosynthesis?

The main variables which affect photosynthesis are light, water, CO2 concentration and temperature.

What abiotic factors affect the rate of photosynthesis quizlet?

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 abiotic factors are needed for photosynthesis?

Sunlight is the main source of energy on Earth, which makes it an extremely important abiotic factor. Sunlight is necessary for photosynthesis, the process where plants use carbon dioxide (CO2) and water to make sugar – food for the plants that later becomes food for animals.

How might abiotic and abiotic factors in the environment affect the rate of photosynthesis?

Abiotic factors include: Light intensity: limited light will limit photosynthesis. This will affect the distribution of plants, and therefore the distribution of animals that eat plants. … Temperature: temperature is a limiting factor for photosynthesis – and low temperature therefore limits growth of plants.

How does abiotic factors affect plant growth?

Temperature and moisture are important influences on plant production (primary productivity) and the amount of organic matter available as food (net primary productivity). Primary production is the synthesis of organic compounds from atmospheric or aqueous carbon dioxide.

What five factors affect photosynthesis and its rate?

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 effects of abiotic factors?

Abiotic factors make up much of the variation seen between different ecosystems. By determining the availability of essential resources such as sunlight, water, oxygen, and minerals, abiotic factors influence which organisms can survive in a given place.

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.

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

During the light-independent reactions, ATP and NADPH from the light dependent reactions are used to produce high-energy sugars. What factors affect photosynthesis? Among the most important factors that affect photosynthesis are temperature, light intensity, and the availability of water.

Which is not a factor affecting the rate of photosynthesis?

Although the light dependent reactions of photosynthesis are not affected by changes in temperature, the light independent reactions of photosynthesis are dependent on temperature. They are reactions catalysed by enzymes. As the enzymes approach their optimum temperatures the overall rate increases.

Which of the following might increase the rate of photosynthesis?

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.
