How does temperature affect the rate of photosynthesis in Elodea?
When the temperature rises the rate of photosynthesis rises also. There is an optimum temperature at which the rate of photosynthesis is maximum. Beyond this temperature, the reaction quickly comes to a halt. Place a pond weed Elodea upside in a test tube containing water at 25°C.
How does temperature affect the rate of photosynthesis lab?
As with other chemical reactions, the rate of photosynthesis increases as the temperature rises. Photosynthesis is controlled by enzymes , which become denatured if the temperature is too high. As a result, the rate of photosynthesis reaches its maximum at an optimum temperature, then decreases.
At what temperature did Elodea photosynthesize the best?
The ideal temperature for elodea ranges from 65 to 75 degrees F (18 to 24 degrees C), but it is able to survive much colder temperatures.
When temperature increases the rate of photosynthesis?
Temperature – Increasing the temperature increases the rate of photosynthesis because more energy is provided. However, if the temperature is increased to above about 45°C, the enzymes that catalyse (speed-up) the reaction begin to denature (not work anymore).
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 the rate of photosynthesis Brainly?
Answer: 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 affect the rate of reaction?
An increase in temperature causes a rise in the energy levels of the molecules involved in the reaction, so the rate of the reaction increases. Similarly, the rate of reaction will decrease with a decrease in temperature.
What temperature will result in the highest rate of photosynthesis?
At medium temperatures, between 50 and 68 degrees Fahrenheit, or 10 and 20 degrees Celsius, the photosynthetic enzymes work at their optimum levels, so photosynthesis rates gauge high. Depending on the particular plant in question, set the greenhouse thermostat to a temperature within this range for best results.
Which factor that affects the rate of photosynthesis?
light intensity
Three factors can limit the rate of photosynthesis: light intensity, carbon dioxide concentration and temperature.
How does temperature affect the photosynthesis rate of Elodea?
The effect of temperature on photosynthetic rate of Elodea (pondweed). We investigated in which temperature plants will produce the biggest amount of oxygen. So then on nwe planet people will have the amount of oxygen needed to live. In this experiment, the relationship between the photosynthesis rate and temperature on Elodea is investigated.
How does light affect the rate of photosynthesis?
Furthermore the amount of oxygen generated indicated the rate of which photosynthesis reactions were occurring. In plants where the light source was of closer proximity more oxygen products were found to be produced. The closer the light was to the plant, the greater light intensity it provided.
How is the rate of photosynthesis of an underwater plant measured?
The plants tested in this experiment were underwater plants (Elodea) and the rate of photosynthesis was measured by the amount of oxygen produced by the plant through photosynthesis. The amount of oxygen produced was measured by counting of the number of bubbles that formed and floated to the surface from the submerged plant.
What should the room temperature be for photosynthesis?
Maintain the room temperature at 20°C. Count the number of oxygen bubbles given off by the plant in a one -minute period. This is the rate of photosynthesis at that particular temperature. The gas should be checked to prove that it is indeed oxygen – relights a glowing splint.
