How do temperatures affect photosynthesis?
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.
How does high temperature affect the rate of photosynthesis?
The higher the temperature then typically the greater the rate of photosynthesis, photosynthesis is a chemical reaction and the rate of most chemical reactions increases with temperature. However, for photosynthesis at temperatures above 40°C the rate slows down.
How does temperature impact photosynthesis and rate of production?
Temperature and rate of photosynthesis It approximately doubles for every 10 °C increase in temperature. Above the optimum temperature the rate begins to decrease, as enzymes are denatured, until it stops.
What affects oxygen production in photosynthesis?
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
How does temperature affect photosynthesis and cellular respiration?
The increase in temperature enhances the rate of cellular respiration. It is due to the heat speeds up the reactions, means the kinetic energy is higher. It means reactions speed up and rate of cellular respiration increases. When temperature decreases, in order to conserve energy, cellular processes slow.
Why is temperature a limiting factor of photosynthesis?
At temperatures above 68 degrees Fahrenheit, or 20 degrees Celsius, the rate of photosynthesis decreases because the enzymes do not work as efficiently at this temperature.
Does temperature affect oxygen production?
How does temperature affect oxygen production? production of oxygen decreases. How does CO2 level affect oxygen production?
Why is temperature important in photosynthesis?
At temperatures above 68 degrees Fahrenheit, or 20 degrees Celsius, the rate of photosynthesis decreases because the enzymes do not work as efficiently at this temperature. This is despite the increase of carbon dioxide diffusion into leaves.
How does sunlight affect oxygen production?
The higher the intensity of light, the more will be the production of oxygen in the form of bubbles by the plants under the process of photosynthesis. Therefore, when you reduce the distance between the light and the plant, there are more oxygen bubbles produced by the plants.
What are the factors affect photosynthesis?
Photosynthesis is affected by light, temperature, water, and CO2. Stomata affect the process of transpiration and do not affect photosynthesis.
How does temperature affect oxygen consumption in cellular respiration?
Explanation: The increase in temperature enhances the rate of cellular respiration. It is due to the heat speeds up the reactions, means the kinetic energy is higher. It means reactions speed up and rate of cellular respiration increases.
How does cold temperature affect photosynthesis?
Low Temperature At low temperatures, between 32 and 50 degrees Fahrenheit – 0 and 10 degrees Celsius – the enzymes that carry out photosynthesis do not work efficiently, and this decreases the photosynthetic rate. This leads to a decrease in glucose production and will result in stunted growth.
How does temperature affect oxygen production quizlet?
If the light intensity is high and the CO2 level is high then more oxygen is created. How does temperature affect oxygen production? production of oxygen decreases.
How is oxygen related to temperature?
First, the solubility of oxygen decreases as temperature increases ¹. This means that warmer surface water requires less dissolved oxygen to reach 100% air saturation than does deeper, cooler water.
How does light and temperature affect photosynthesis?
(ii) Temperature: Temperature combined with other environmental conditions affects photosynthesis is low because the enzymes are affected adversely. At high temperature also the enzymes get denatured and the rate of photosynthesis declines. The optimum range of temperature for photosynthesis is 20oC -35oC.
How does temperature affect oxygen concentration?
Cold water can hold more dissolved oxygen than warm water. In winter and early spring, when the water temperature is low, the dissolved oxygen concentration is high. In summer and fall, when the water temperature is high, the dissolved-oxygen concentration is often lower.
What are the effects of light intensity on the rate of photosynthesis and oxygen production in plants?
As the light levels are increased there is an increase in oxygen (bubble) production from photosynthesis of the plant. This increase slows down progressively at higher light levels.
How do each of the following factors affect the productivity in the process of photosynthesis temperature water carbon dioxide?
Hey…
- The rate ofphotosynthesis increases with increase intemperature.
- The rate ofphotosynthesisdecreases if the availability of water is less. photosynthesismay stop also if water is not available at all.
- The rate ofphotosynthesis increases with increase in carbon dioxide.

How does temperature affect cellular respiration in plants?
The cellular respiration in plants decreases with a decrease in temperature until the point– when a further decrease in temperature will lead to the freezing of the tissues and plants. The rate of reaction is directly proportional to the change in temperature.
Why does photosynthesis decrease during high temperatures?
Photosynthesis is an enzyme mediated process. We know that enzymes work in optimum range of temperature. When the temperature goes beyond this range, an enzyme cannot work. Due to this, the rate of photosynthesis decreases at higher temperature.
What is the ideal temperature for photosynthesis?
The optimum temperature range for photosynthesis is 35–40ºC.
Does temperature affect oxygen?
Air and Water Temperature Increases Lower levels of dissolved oxygen due to the inverse relationship that exists between dissolved oxygen and temperature. As the temperature of the water increases, dissolved oxygen levels decrease.
Does oxygen content change with temperature?
Show activity on this post. Below 90.19 K there is definitely an effect of temperature on the % oxygen in air, as it condensates out. So as general as the question is stated in the header, the answer is 'yes'.
Does oxygen consumption increase with temperature?
In general, the rate of oxygen consumption and ammonia excretion was found to enhance with increasing temperature.
Why does oxygen production increase as light intensity increases?
Oxygen production increased as the light intensity increased due the greater availability of light energy for photosynthesis.
How does light intensity affect oxygen production hypothesis?
As the light levels are increased there is an increase in oxygen (bubble) production from photosynthesis of the plant. This increase slows down progressively at higher light levels. This result suggests that my hypothesis was correct. intensity increases.
Does temperature play a role in cellular respiration?
A change in temperature affects the- rate of cellular respiration significantly. An increase in temperature results in the absorption of heat, thus making the reaction endothermic.
Does higher temperature increase photosynthesis?
Apparent photosynthesis decreased with increasing temperature, from 20 to 40° and its rate was affected by both light intensity and oxygen concentration.
Why does temperature affect the dissolved oxygen concentration?
Cold water holds more oxygen molecule than hot water because water molecules are closer together in cold water which makes it harder oxygen molecule to escape. At higher temperature, the oxygen molecule have greater amount of kinetic energy.
Why is oxygen production lower in cold temperatures?
Low temperatures cause your blood vessels to narrow which restricts blood flow and reduces oxygen levels. In order to circulate blood properly through the constricted vessels, your heart must pump much harder than usual.
