What are three 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 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.

What are five factors that affect the rate of photosynthesis?

Temperature light intensity carbon dioxide levels water oxygen and chlorophyll. The rate of photosynthesis increases as the temperature increases.

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.

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

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

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.

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.

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

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 factors affect photosynthesis and cellular respiration?

Explanation:

• the intensity of the light being absorbed by the chloroplasts.
• the concentration and availability of CO2 (Carbon Dioxide)
• the temperature.

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 the 3 types of photosynthesis?

The three main types of photosynthesis are C3 C4 and CAM (crassulacean acid metabolism). In college I had to memorize some of their pathways and mechanisms but I will highlight what gives one an advantage over another and what types of crops forages and weeds have specialized C3 and C4 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?

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. …

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.

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 is the effect of photosynthesis?

photosynthesis the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants light energy is captured and used to convert water carbon dioxide and minerals into oxygen and energy-rich organic compounds.

What factors affect respiration in plants?

For most plant species temperature acidity salt concentration and the amount of moisture carbon dioxide and oxygen are some of the additional important factors which affect respiration.

What are the factors that affect the respiration rate of yeast?

The rate of respiration is influenced by different ​factors​(e.g. temperature pH nutrient availability). The effect of each of these factors can be determined by changing ​one variable only​ and observing its effect on the rate of reaction.

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 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.

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.

Which of the following will not affect photosynthesis?

Answer: The absence of oxygen will have no effect on the process of photosynthesis. This is because the photosynthetic process utilises water and carbon dioxide to produce oxygen and carbohydrate in the presence of chlorophyll and sunlight.

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

Temperature: It increases up to a point (because of increased molecular collisions) until it hits a certain temperature and then the enzymes denature and it stops working. Light intensity: As light intensity increases so does the rate of photosynthesis. This is only until a certain point.

How does increased co2 affect photosynthesis?

Studies have shown that higher concentrations of atmospheric carbon dioxide affect crops in two important ways: they boost crop yields by increasing the rate of photosynthesis which spurs growth and they reduce the amount of water crops lose through transpiration. … During that process they release water vapor.

How 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.

What three abiotic factors affect photosynthesis?

The rate of photosynthesis in a plant can be determined by three external factors: temperature light intensity and available carbon dioxide concentration.

What are some environmental factors 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 is the cause of photosynthesis?
