Why Would It Be Hard To Find The Ideal Light Intensity If The Temperature Were Very Hot?

if the temp were extremely hot or cold, then oxygen production would be near zero no matter what light intensity value you use. if the light intensity were very low, then the oxygen production would be near zero no matter what C02 level you use.

Why would it be hard to find the ideal light intensity if the temperature were very hot or cold gizmo answers?

It would be hard to find the ideal light intensity if the temperature were too hot or cold because the environmental conditions of the plant would prevent the reactions to be accurate.

How does temperature affect light intensity?

Light dependent reactions use light energy and so are not affected by changes in temperature. As light intensity is increased further, however, the rate of photosynthesis is eventually limited by some other factor. So the rate plateaus.

How does temperature affect photosynthesis?

Temperature. … 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 ideal conditions for photosynthesis light intensity?

canadensis has an optimal photosynthetic rate at light intensities of 6000 lux. At greater intensities oxygen inhibition begins to occur due to the ability of the enzyme ribulose phosphatase to act in both photosynthesis and cellular respiration.

What are the ideal conditions for photosynthesis gizmo?

Introduction: Photosynthesis requires light, water, and CO2 to work. When one of these factors is in short supply, it is called a limiting factor. Temperature can also be a limiting factor when it is too hot or too cold for photosynthesis to work well.

How does light intensity affect the rate of 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.

How does intensity change with temperature?

The intensity (or flux) at all wavelengths increases as the temperature of the blackbody increases. The total energy being radiated (the area under the curve) increases rapidly as the temperature increases (Stefan–Boltzmann Law).

How does temperature light intensity and wind affect transpiration?

Solution: Temperature: Transpiration is faster on hot summer days as compared to cold winters. Light intensity: The transpiration rate is increased due to the increase in light intensity. … Wind: Transpiration is more when the wind is blowing faster as water evaporates faster from the leaves.

Why does light intensity increase the rate of transpiration?

If the rate of transpiration increases, the rate of absorption of water by the root increases too.

Why is temperature necessary for photosynthesis?

Temperature. … 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 .

Does heat increase photosynthesis?

High Temperatures

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.

Does heat speed up 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.

Why is light intensity important for 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.

Why is light intensity a limiting factor of photosynthesis?

Light. As light intensity increases so too does the rate of photosynthesis until a certain point where the graph levels off. At lower light intensities, light is the limiting factor because an increase in light causes an increase in photosynthesis.

What are ideal conditions for photosynthesis?

To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.

What light intensity and co2level do you think will maximize the rate of photosynthesis?

In the Gizmo, what light intensity and CO2 level do you think will maximize the rate of photosynthesis? The highest light intensity and CO2 level will maximize the rate of photosynthesis.

How does light intensity affect oxygen production?

Oxygen production increased as the light intensity increased due the greater availability of light energy for photosynthesis.

What was the ideal light intensity for maximal oxygen production?

6000 lux. The effect of light intensity followed a Michealis-Menten curve where increases in light intensity corresponded to increases in oxygen production until a peak in oxygen production occurred at a light intensity of 6000 lux.

How does light intensity affect the rate of photosynthesis quizlet?

As light intensity increases (distance between lamp and plant decreases) the volume of oxygen (or the rate of bubble production) increases. This indicates that the rate of photosynthesis increases with light intensity.

How does light intensity affect plants?

Light intensity influences the manufacture of plant food, stem length, leaf color and flowering. Generally speaking, plants grown in low light tend to be spindly with light green leaves. A similar plant grown in very bright light tends to be shorter, better branches, and have larger, dark green leaves.

How does light intensity and the rate of photosynthesis relate to the position of the sun?

The rate of photosynthesis relies on light intensity because when sunlight is limited, so is photosynthesis. This means that in the winter (when there are less hours of sunlight) and at night (when there is no sunlight at all), there is less photosynthesis.

Is intensity of light proportional to temperature?

Wein’s law tells you that the wavelength where the largest energy density is emitted from a black body is inversely proportional to the temperature of the body. It states . We can use this to tell how hot stars are by looking at the wavelength of light they emit. E= n*h*ν.

What is the relationship between intensity of light and resistance?

Resistance of an LDR is inversely proportional to the intensity of light that falls on LDR’s surface. In other words, with an increase in light intensity, the resistance of photoresistor or LDR decreases.

How does the temperature affect the colors that are seen?

All objects that have temperature emit light. The hotter the object, the brighter and bluer the light emitted will be. … Objects also reflect light that hits them, which determines the color of the object. Lighter-colored objects emit more light, and darker colored objects absorb more light.

How does light intensity affect air temperature?

The environmental variables inside the canopy under a high light intensity were characterized by higher air temperature, higher vapor pressure, and lower CO2 concentration than those outside the canopy.

Why does temperature affect transpiration?

Higher temperatures cause the plant cells which control the openings (stoma) where water is released to the atmosphere to open, whereas colder temperatures cause the openings to close. … Wind and air movement: Increased movement of the air around a plant will result in a higher transpiration rate.

How does light intensity affect ecosystem?

The two most important climatic factors for ecosystems are sunlight and water. Sunlight is necessary for plants to grow, and to provide energy to warm the earth’s atmosphere. Light intensity controls plant growth. … At the other maximum, some plants and animals only survive by being submersed in water.

Why the rate of transpiration is more if the velocity of wind is more?

The rate of transpiration depends on various factors like humidity, temperature, sunlight, atmospheric pressure and wind speed. As the wind blows faster, the water released by transpiration is carried away faster. So, rate of transpiration increases with velocity of wind speed.

What would increase the rate of transpiration?

How does light intensity affect the opening of stomata?

High light intensity during growth increased the stomatal frequency but there were only small changes in the length of the stomatal pore. High-light leaves had more than twice as many stomata per unit area as low-light leaves.

How does temperature affect enzymes in photosynthesis?

The chemical reactions involved in photosynthesis are controlled by enzymes . 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 does temperature affect photosynthesis lab report?

Temperature has an effect on the photosynthetic rate of organisms as increasing temperature increases kinetic energy, which has been found to increase the rate of photophosphorylation (Lambers et al. … In our experiment, an increased rate of photophosphorylation was measured by an increase in oxygen production.

What happens to photosynthesis when temperature increases?

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).
