What are the factors that affect the rate of 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 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 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.

Which of the following would have affect the rate of photosynthesis?

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

What is photosynthesis rate?

The rate of photosynthesis is a gross measure of the rate at which a plant captures radiant energy and fixes it in organic carbon compounds. … The compensation point is the intensity of PAR at which the gain from gross photosynthesis exactly balances the respiratory and other losses.

What factors affect photosynthesis lab?

1) the variables of light intensity temperature carbon dioxide light quality all influence the rate of photosynthesis.

What makes photosynthesis happen faster?

Increasing the light intensity will make photosynthesis faster. … Carbon dioxide level – Photosynthesis can be limited by the level of carbon dioxide. Even if there is plenty of light a plant cannot photosynthesise if it has run out of carbon dioxide.

What is class 3 photosynthesis?

Photosynthesis is a process in which green plants use energy from the sun to transform water carbon dioxide and minerals into oxygen. Photosynthesis gives us most of the oxygen we need in order to breathe.

How does temperature affect the rate of photosynthesis Class 10?

The rate of photosynthesis is influenced by temperature. Higher the temperature greater the rate of photosynthesis. This is because photosynthesis is a chemical reaction and most of the chemical reactions are accelerated with temperature. … At higher temperatures the enzymes simply do not operate and get denatured.

How does light affect photosynthesis What are the various factors affecting photosynthesis Class 10?

Various factors influence/affect the photosynthesis process. … Light Intensity: More the light the more will be the rate of photosynthesis. Similarly low light will lead to a low rate of photosynthesis. The Concentration of CO₂: A higher CO₂ concentration rate in a plant also accelerates the photosynthesis process.

What are the internal factors that affect the rate of photosynthesis?

Some of the internal factors which affect the rate of photosynthesis include the chlorophyll content of leaves protoplasmic factor accumulation of by-products leaf anatomy age of the leaf and hormones. The rate of photosynthesis is not proportional to the quantity of chlorophyll present in leaves.

Which factor can affect the rate of photosynthesis by denaturing enzymes in the plant?

temperature

As temperature increases the number of collisions increases therefore the rate of photosynthesis increases. However at high temperatures enzymes are denatured and this will decrease the rate of photosynthesis.

How do 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 are the 6 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.

Does water affect the rate of photosynthesis?

Water affects the rate of photosynthesis indirectly. Water stress causes the stomata to close and thereby reduces carbon dioxide availability. … Water stress also results in wilting of leaves and therefore reduces metabolic activity performed by leaves.

Which of the following will not affect photosynthesis?

Oxygen is not a limiting factor in photosynthesis.

How external factors affect the rate of photosynthesis?

Factors affecting photosynthesis are: Carbon dioxide – increase in the concentration of carbon dioxide can enhance the rate of photosynthesis. The intensity and quality of light affects the rate of photosynthesis. … Photosynthesis is sensitive to higher temperatures as high temperatures cause the inactivity of enzymes.

How do the factors required for photosynthesis affect the rate of photosynthesis?

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.

What are the five external factors that could increase the rate of photosynthesis?

Photosynthesis could be enhanced by increasing the concentration of CO2.

Compensation Point or Threshold Value. …
2) Irradiance or Light Intensity. …
High light intensity. …
Photo-inhibition. …
Photo-oxidation. …
Wavelength of light. …
Duration of light. …
3) Temperature.

What are the 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.

How does water affect the rate of photosynthesis in plants Class 10?

Answer: Water controls the opening and closing of stomata. The deficiency of water causes stomata to open very little or it may even remain closed. Therefore G02 (required as a raw material for photosynthesis) cannot enter into the leaves and thus lack of water slows down the rate of photosynthesis.

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 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 factors affect the rate of cellular respiration?

We’ll first review what cellular respiration is and then explore how three factors affect it: temperature glucose availability and oxygen concentration.

How light intensity affects the rate of photosynthesis experiment?

More oxygen bubbles are produced when the light is closer to the beaker. So a greater light intensity gives a greater rate of photosynthesis.

How does photosynthesis rate affect plant growth?

Increasing photosynthesis increases carbon availability for plants. Whether or to what extent that translates into increased growth depends on the nature of colimiting factors especially nutrient availability.

How do you determine the rate of photosynthesis?

Where does the rate of photosynthesis do not depend?

The rate of photosynthesis does not depend upon light duration. Explanation: Photosynthesis is the process of producing food with the help of light. In this method the light energy is converted into chemical energy.
