What Three Factors Affect Photosynthesis


Does water affect photosynthesis?

Water affects the rate of photosynthesis indirectly. Water stress causes the stomata to close thus reducing the availability of CO2. It also causes the leaves to wilt reducing the surface area for photosynthesis.

  • 3) Temperature.

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 internal factors of photosynthesis how do they affect photosynthesis?

Answer: Many external and internal factors affect the rate of photosynthesis. The external or environmental factors at:A light intensity carbon dioxide concentration and temperature. The internal factor influencing the photosynthesis is chlorophyll content of the leaves and protoplasmic factors.

What happens during photosynthesis 4th grade?

When plant cells have water carbon dioxide and sunlight the chemical process of photosynthesis occurs. When this happens the water carbon dioxide and sunlight join together to form a sugar called glucose plus water and oxygen.

Why does CO2 concentration affect photosynthesis?

Carbon dioxide and rate of photosynthesis An increase in the carbon dioxide concentration increases the rate at which carbon is incorporated into carbohydrate in the light-independent reaction and so the rate of photosynthesis generally increases until limited by another factor.

What are the factors that affect 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 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.

Does temperature affect 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 .

Which of the following will not affect photosynthesis?

Oxygen is not a limiting factor in photosynthesis.

What are the 3 limiting factors in plants?

There are three main factors which limit the rate of photosynthesis:

  • Temperature.
  • Light intensity.
  • Carbon dioxide concentration.

How does light affect photosynthesis?

As you rise from low light intensity to higher light intensity the rate of photosynthesis will increase because there is more light available to drive the reactions of photosynthesis. … At a very high intensity of light the rate of photosynthesis would drop quickly as the light starts to damage the plant.

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.

GCSE Biology: Factors Affecting Photosynthesis

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 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). The rate of photosynthesis increases as light intensity increases.

What are the 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 is photosynthesis 5th grade?

Photosynthesis is the big name for the process by which plants convert energy from sunlight into energy for food. This process also requires water and carbon dioxide. … In this form the plants can use the glucose and water for food and release the oxygen back into the air for consumption by animals including humans.

What is the three limiting factors?

Some examples of limiting factors are biotic like food mates and competition with other organisms for resources. Others are abiotic like space temperature altitude and amount of sunlight available in an environment. Limiting factors are usually expressed as a lack of a particular resource.

How do oxygen levels affect photosynthesis?

The effect of oxygen on photosynthesis depends on plant species and on some internal and environmental conditions. Oxygen inhibits the photosynthesis of C3 plants at atmospheric CO2 concentration (Varburg effect). … Inhibition of photosynthesis by oxygen is reduced by increase of the C02 concentration.

Factors affecting the rate of Photosynthesis – GCSE Biology (9-1)

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.

Factors That Affect the Rate of Photosynthesis | Biology for All | FuseSchool

What is photosynthesis 4th grade?

Photosynthesis​is a process by which plants make their own food in their​ ​leaves​ ​and give off oxygen and water that they are not using.

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 are four limiting resources for plants?

In the natural world limiting factors like the availability of food water shelter and space can change animal and plant populations.

How do plants increase photosynthesis?

A high day temperature can increase photosynthesis especially when light and CO2 are not limiting. However respiration also increases with temperature because plants need more energy to support the increased rate of cell division and expansion.

What Three Factors Affect 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.

How do limiting factors affect photosynthesis?

Interaction of factors limiting the rate of photosynthesis -…

  • the rate of photosynthesis increases until factors becoming limiting.
  • if carbon dioxide concentration is increased the rate increases further and then another factor becomes limiting.
  • the rate can be increased further if the temperature is increased.

What are the three factors required 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 3 factors that affect the rate of photosynthesis quizlet?

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

What factor affects the growth of plants in relation to photosynthesis?

Photosynthesis is the process by which green plants manufacture food mainly sugars from carbon dioxide and water in the presence of chlorophyll (a green pigment) utilizing light energy and releasing oxygen and water. Together the quality quantity and duration of light influences plant growth.
